UNDERSTANDING OUR DATA MODEL

TGS Longbow™ operates in the cloud – meaning that you, the user, can access our nationwide database

of Well Performance Data in lightning fast speeds.

Longbow™ uses cutting edge technology to source all well performance data made digitally available in

the continental U.S., as well as in Alaska, Canada and the Gulf of Mexico.

Our talented team of Production Data Analysts imports the data from these sources and runs it through

a series of quality checks before it is exported to the cloud. We strive not to alter the original data in any

fashion, though we do check for outliers and blatant errors, and use the original data to calculate and

store many value-added attributes used by clients to make better business decisions.

Additionally, our application manages a host of calculated performance cums, permit data and integrates

with other TGS products and Log-Line Plus! ™. Our database is updated twice a month data – permit data

updated daily.

Longbow™ Reporting Level Definitions

Lease Level - Well information and production data that is reported as an entire lease. A total

monthly cumulative is reported for the entire lease life but by using one of three allocations, each

lease can be broke down to the well level.

Well – Production data that is reported from the regulatory agencies down to the well level,

where each well is individually accounted for and recorded.

Well Formation – Production data that is reported from the regulatory agencies down to the

formation level. If a single well produces from multiple formations, the individual formation

production streams for the well will be reported. The Well formation level is similar to the well

reporting level.

Group – Production data that is reported from the regulatory agencies at the group level, which

are grouped and represented as a batch of wells from the same field.

3

A WORD ON ALLOCATIONS AND CALCULATED VALUES

Since production is reported at a lease level for many states, breaking that data down to the well level is

important for any well-level analysis. Longbow contains three Lease-to-Well allocation algorithms which

are run against the database every month. To develop allocation percentages for each well, certain

information is required about the wells that may or may not be public. Completion dates, first production

dates, plug dates and well tests are generally available from each state, but shut-in dates, temporarily

abandoned dates and convert to injection dates may not be available. By not having dates when the wells

stopped/started producing (from shut-in or TA status for example) the allocation will have some inherent

error due to the lack of information. Allocating state lease production data, even with the error potential,

results in useful information for quickly determining the production trends of each well on the lease.

When allocating lease production from state data sources there are three main assumptions that must be

made:

Each well is producing from its first production, completion or spud date, whichever is available.

If no date is available, then the well is assumed to produce the entire life-span of the lease.

Each well is producing until its plug date.

All production test values are assumed to be reported on the same time-scale.

The three lease-to-well allocation methods currently used are:

1/N – Divide lease production by the number of wells producing every month to get the allocation

percentage and apply it to the lease production.

Step – Use the most recent test data to calculate a well’s allocation percentage every month and

apply it to the lease production.

Straight-Line – Decline the test data by calculating the line between the most recent pair of test

values every month, find the allocation percentage from the calculated test values and apply it to

the lease production.

Each of these assumptions and methods is intended to make the best use of the available data to calculate

the most accurate allocation percentages. Having several allocation methods also allows for a

customizable approach to calculating the most accurate data for a well. If other parameters are provided

such as well shut-in or TA dates, workover dates and pre-post workover rate tests, the allocation can be

further refined to reflect what actually happened to each well on the lease.

FUNCTIONALITY OF THE QUERY GRID

OVERVIEW OF THE QUERY GRID

The Query Grid is your starting point for building, managing and running your queries. Saved queries are

organized by Query Name, Data View, Data Source, Data Source Type and Last Run Date.

FUNCTIONALITY OF THE QUERY GRID

Selector Tools:

Run button – Click the Run button to open or ‘run’ a saved query. This will update this query with

the most current performance data associated with the records on the saved query.

Add button – Click the Add to start a new query.

Duplicate button – Click the Duplicate button to create a copy of a saved query.

Rename – Click the Rename button to rename a saved query.

Delete – Clicking the Delete button will delete saved query from the query grid.

Import – Click the Import button to import a shared query from an xml file.

Export – Click the Export button to export the xml file for your saved query and share it with other

Longbow users.

Organize – The Organize button organizes the structure of your Query Grid. You can organize by

Name, Data View, Data Source, Data Source Type and Last Run Date.

Beginning a New Query

Click the Add button to start a new query. This will open the query editor, where you will begin to query

on TGS Well Performance Data records in a SQL format. For more information on how to query, skip to

the Building Your Query in U.S. Wells Data View section on the next page.

BUILDING YOUR QUERY IN U.S. WELLS DATA VIEW

U.S. Wells Data View Overview

The U.S. Wells data view contains well header data attributes such as API, State, State Well ID, County,

Field, and Operator. The view also provides production volumes for every producing well in the United

States, with perforation and IP test data when reported.

Adding a New Query

To begin a new query, select Queries from the Longbow Toolbar, then click the green Add button on the

bottom panel. When the Query Editor screen appears, enter a name for the query, choose the database

that you want to query from, and enter your filter values. Use the Test button to see how many records

satisfy your search criteria. Click the Add button to create & save the query to the list of queries in the

navigation tree.

Building a Query

A query is composed of one or more query filters, and a query filter has three parts:

The Data Field, which is the column of data that you want to query.

The Comparison, which is the operator such as Equals, Less Than, or Contains that you want to apply

to your data field.

The Filter Value, which is the actual value used to filter the data.

For example, if you wanted to search the database for all wells in the state of Texas, you would select

State as your data field, set the comparison to Equals, and enter “Texas” as the filter value. Comparison

values default to Show All to include a broader search [see Figure 1]. You can manually enter filter values

[Figure 1]

6

by typing them into the empty field of the Filter Value, or you can choose filter values directly from your

database.

To choose filter values from the database, click into the empty Filter Value field and a button with three

dots will appear, this is the Ellipsis button [see Figure 1]. Clicking this button produces the Filter Value

window that shows all distinct values for the current data field. You can select database values directly

from this window with the checkboxes in the grid.

If you wanted to further qualify your search with wells only from a specific county, you would find the

County data field, set the comparison to Equals and type in the name of the county in the Filter Value.

*Note: In order to avoid error, we recommend clicking into the Filter Value field and using the ellipsis

button to select your data even if you are confident in the spelling of the filter value.

To broaden your search and include multiple counties, use In the List of as your comparison value and use

the ellipsis button to select the filter values which pertain to your county(s) [see Figure 2].

By specifying multiple filters, you can select only those records that interest you, despite the database

having an underlying millions of records.

[Figure 2]

7

When you filter a data field, the Query Editor populates a dropdown list of comparisons that apply to that

data field. For example, if you select a numeric data field, you can use comparisons such as Equals, Greater

Than, Less Than, or Between. Text fields offer comparisons such as Starts With, Ends With, In the List Of,

and Contains. Date fields provide comparisons such as After and Before.

If you want to clear all of your current query filters, use the Clear All button. Likewise, if you want to clear

a specific filter, you can select the filter in the query grid, and press the Clear Current button.

The Test button will return a count of records that satisfy each query filter that you define.

When you are satisfied with your query, press the Save button to save the query and run it. After the

query runs, your query results will automatically populate the grids, charts, maps, and reports that are

associated with the query.

*Special Note about Building a Query in Different Data Views: When building a query within Longbow™

the default data view will be U.S. Wells. When building a query under any other data view the functionality

will be the same with only the available attributes differing [move to “Querying for Permit Data” section].

Saving your query

When you are satisfied with your query and have added your new query by clicking Add, press the Save

button to save the query and run it. After the query runs, your query results will automatically populate

the grids, charts, maps, and reports that are associated with the query.

After you have saved a query and would like to modify it, you cannot save the query again under the same

name. If you would like to make changes to an existing saved query you will need to click the Save As

button and save your query under another name.

Exporting XML file & Sharing Your Query

After you run and save your query, click the Export to File button [see Figure 3]. Choose your destination

and click Save. This feature allows users to save a copy of the XML file to their system and share saved

queries amongst their peers.

[Figure 3]

OVERVIEW OF THE TREE PLUGIN

The Tree tab provides a wide scope of data and displays this data is an easy to manipulate tree structure.

By selecting what tier level of data you are interested in, you can review the production data on a lease

level when working with a lease reporting state, or review allocated production on the well level. Within

the Tree plugin-in are additional tabs with informative data including: Well header data, Current Lease

Production, Summary Formation Production (Formation reporting state), Allocated Production (N, Step,

and Line), Well Production Tests, and Well Perforations.

FUNCTIONALITY OF THE TREE

Selecting Wells on the Tree

The column on the left represents a breakdown of your query depending on which level you would like to

prioritize. You can customize which levels you would like to see by navigating down below to the Settings

button, which will allow you to add or remove levels in the tree and set priority.

Clicking a broader level in the tree, such as county or operator, will show a summary of formation or lease

production. In order to view the individual well, click the well name, which will populate the well header

with the production data available for that well.

To clear the selected wells that are checked, click the Clear button.

To view the Summary Lease Production for an entire lease, check the boxes and click the Summary button.

Each row displays the monthly production volumes. The same output options to print,

copy, export or send to Excel are found within the data grid.

PRACTICE

Finding Well-level Production in Lease States

In order to see the well-level production data in lease states, you must begin your query in a state where

the reporting is at a lease level, such as Texas, Oklahoma, Louisiana, etc. When querying lease and well-

formation states, be sure to pull from the Lease or Well Formation Statistics data menus throughout the

application. After doing so, the tree will populate all the information that is reported from the state and

calculate the allocations data for you in all three allocated data tree plugins.

Adding data sets to the Summary Formation Production graph

To add data to your graph in the Summary Formation view, navigate to the right-hand column where you

see the Graph Settings. From there, scroll down to the Data Sets menu and select the empty check box

next to the data that you would like to populate.

Adding/Removing tree levels using the Settings button

Click the Settings button to bring up a menu where you can modify the tree settings. You can add or

remove tree levels by using the “> or <” (one level) and “>> or << “ (all levels). You can also prioritize the

tree levels by using the Move buttons.

Zooming in on a monthly or daily level in the Summary Formation Production graph

The Summary Formation Production graph defaults to a yearly view. To get monthly or daily production

views on a particular section on the graph, draw a box around the section on the graph that interests you

and it will zoom in/time-step every time a box is drawn.

11

OVERVIEW OF THE MAP PLUGIN

The Map plug in helps you visualize your Longbow™ query and build sub-queries. The map is interactive,

allowing you to build upon different sets of data and settings in real-time, allowing you to control how

your query is visualized for presentation purposes. With the use of the Show Drilldown tool, you can

create sub-queries within the map and create charts and graphs relevant to the data you have selected

on the map. The map is easily exportable and communicates with Log Line.

FUNCTIONALITY OF THE MAP

Selector Tools

The Select pointer tool allows you to select one well at a time. When the well is selected, it will turn red.

The Rectangle Select tool allows you to select a group of wells by drawing a square around the group of wells.

The Circle Select tool allows you to select a group of wells by drawing a circle around the

group of wells.

When wells are selected, they will turn red. To hide the red coloring, click the Hide button and your wells will remain selected but the red coloring will be hidden.

To select all wells on your map, click the Select All button.

To clear all previously selected wells, hit the Clear All button. You have now removed any selections from the map.

8. After creating the quick filter, Longbow™ automatically assigns colors based on the filtered data;

make sure none of your filtered data was assigned the color blue. The Longbow™ default setting

for wells which are not assigned a filter is blue. Therefore, changing the color for

unassigned/filtered wells creates a more accurate and defined map.

Creating Bubble Maps

1. Use the rectangle selection tool to select a group of wells from the map.

2. To assign bubble values to your map, toggle the Data and Settings Panel on, then click Bubbles

under the Data menu.

3. Click the Bubble Data ellipsis button to begin defining bubble data.

4. In this example, we want to create a bubble map based on ‘Lease Oil Total Cum’ because we are

using statistics from a lease-level reporting State. To do this, scroll down to the menu for ‘Lease

Statistics’ and click on ‘Lease Oil Total Cum.’

5. From here, adjust the appearance of your bubble by color, transparency, size, minimum and

maximum volumes.

6. Further customize your bubble data and color by selecting the ellipsis button next in the Bubble

Color field. From here, you can set default colors, a gradient based on a range of values, or assign

colors based on data field filters. To assign color based on these filters, click the 3rd radio button

that says “Assign Colors Based On Data Field Filters” and then click the Quick Filter button.

*Note: the 1st radio button will assign one color to your entire data set. The 2nd radio button will

create a gradient of colors to represent a range of values for your selected data set.

7. Choose the data field in the column on the left that you would like to populate.

8. Click the Select button and choose the data from the drop down menu.

9. Click OK when you are done.

15

10. After creating the quick filter, Longbow™ automatically assigns colors based on the filtered data;

make sure none of your filtered data was assigned the color blue. The Longbow™ default setting

for wells which are not assigned a filter is blue. Therefore, changing the color for

unassigned/filtered wells creates a more accurate and defined map. Alternatively, you can change

the unassigned symbol color to Transparent using the dropdown menu at the bottom.

Creating Contour Maps

1. Use the rectangle selection tool to select a group of wells from the map.

2. To create a contour map between the selected wells, toggle the Data and Settings Panel on, then

click Contours under the Data menu.

3. Click the Show radio button.

4. Use the Contour Data ellipsis button to select that attribute that you would like to contour.

Lease/Well: Select Lease/Well to export the WellID, LeaseID and StateLeaseID of your selected

wells. *Note: In order to view the data on the well-level, be sure to always select this export

option when exporting wells that are in lease or group states.

Production Data: Select Production Data to export the production volumes of your selected

wells. Please see the Production Data Documents, Articles, and White Papers section on the

Welcome Page and select the file “Export Data Level Grid” to view the production level for each

state. You can navigate to the Welcome Page by clicking the Help button.

After you have determined the production level of your state of interest, check the box beside

Wells, Formations, and/or Leases to export your production volumes.

Select the allocation type you would like your exported production data to have by checking the

box beside Line, Step, and/or Divide by N. You can export a specific Production Data Range by

inserting a start and end date in mm/dd/yyyy format.

Formations: Select Formations to export the well formation data.

Well Tests: Select Well Test to export the production test data for your wells, if available

Perforations: Select Perforations to export the perforation data for your wells, if available.

Production Level

Wells: Use this selection when exporting wells that are reported at the well level.

Formations: Use this selection when exporting wells that are reported on the formation level.

Leases: Use this selection when exporting wells that are reported on the lease or group level.

Allocations Type

To develop allocation percentages for each well, certain information is required about the wells that

may or may not be public. Completion dates, first production dates, plug dates and well tests are

generally available from each state, but shut-in dates, temporarily abandoned dates and convert to

injection dates may not be available. By not having dates when the wells stopped/started producing

(from shut-in or TA status for example) the allocation will have some inherent error due to the lack of

information. Allocating state lease production data, even with the error potential, results in useful

information for quickly determining the production trends of each well on the lease.

Each of these assumptions and methods is intended to make the best use of the available data to

calculate the most accurate allocation percentages. Having several allocation methods also allows for a

customizable approach to calculating the most accurate data for a well. If other parameters are

provided such as well shut-in or TA dates, work over dates and pre-post work over rate tests, the

allocation can be further refined to reflect what actually happened to each well on the lease.

Line: Decline the test data by calculating the line between the most recent pair of test values

every month, find the allocation percentage from the calculated test values and apply it to the

lease production.

Step: Use the most recent test data to calculate a well’s allocation percentage every month and

apply it to the lease production.

Divide by N: Divide lease production by the number of wells producing every month to get the

allocation percentage and apply it to the lease production.

Each allocation method has its strengths and weaknesses. The 1/N allocation method is very

straightforward, fast and easy to understand. However, by not adjusting the allocation percentage to

match the well test ratios, some error is introduced. The 1/N method must be used as a backup method

within the Step and Straight-Line allocation methods when no tests are available for specific wells.

Production Date Range

Use this tool to export the Well Performance Data relative to a specific start/end date.

Export Selection Combinations and Outputs

File Naming Conventions

The data combinations that you select before exporting will determine the type and number of files. In

general, you will receive a separate file for every Export Option, Production Level and Allocation Type

selected. All files use the following naming convention: “Query Title_Production Level_Export

Option(s).”

21

Well States: Most users will export Well Headers, Production Data, Well Tests and Perforations.

In this instance, you will receive 4 separate Excel files representing those selected data sets.

Lease/Group States: Lease and group states will also export separate files for the Well Headers,

Production Data, Well Tests and Perforations for the entire lease. In addition, the user will select

the Lease/Well relationship in the Export Options menu, and Lease in the Production Level

menu. In this instance, users will receive an additional 4 files representing the Well Headers,

Production Data, Well Tests and Perforations, but it drilled down to the lease/well level.

Allocated Data: When an Allocation Type is selected, Longbow™ will export separate files for

the Well Headers, Production Data, Well Tests, Perforations and Lease/Well that represent the

allocated values, per well.

PRACTICE

Exporting lease/group state wells

Since production is reported at a lease level for many states, breaking that data down to the well level is

important for any well-level analysis. To export wells in a lease/group state, select the following options:

Export Options: Select Well Header, Lease/Well and Production Data. Formations, Well Tests

and Perforations can also be selected.

Production Level: Select Leases.

Allocation Type: Select any or all of the allocation types and you will receive a separate file per

each allocation type with their respective values.

Formatting Excel files

When exporting wells to a CSV file, it follows the same formatting rules as specified by the target

system; in most cases, this would be Excel. The CSV file is completely customizable and the data and

columns can be adjusted to your liking before importing to another interpretation system. It is

particularly important to adjust the columns so that they map properly to your target system before

attempting to import the CSV file. In most target systems, you can save the template layout/mapping

attributes to create a custom import for future use.

Sometimes you may need to adjust the formatting of certain fields/columns. In most cases, the user has

to adjust the API because it is exported in scientific notation. However, this is an easy fix:

First, select the entire column by clicking on the column header. Right-click and select Format Cells.

Under the Category menu, select Number. Set the decimal places to 0 and click Ok. The API column

should now display 14 digit APIs.

QUERYING FOR PERMIT DATA IN THE U.S. WELLS AND PERMITS DATA VIEW

U.S. Wells and Permits

The U.S. Wells and Permits data view contains well header and permit data attributes such as API, State,

County, Field and Operator. This data set is not part of the Oyster Plus license and is purchased under

separate agreement.

Selecting Longbow Data Sets in U.S. Wells and Permits Data View

Permit data is housed on a separate table from the TGS Well Performance Data but are queried as one.

When building a query in the U.S. Wells and Permits data view, it is necessary to select the data sets, or

tables, that you would like to pull from.

Common Data Elements between U.S. Wells Data View and Permit Data View:

State

County

Field

Operator

Lease Name/Well Name

Well Number

Well Formations (Projected Formation)

Well Status

Well Type

API, API State, API County

Well Location Surface & Bottom

To view producing and non-producing U.S. wells only, uncheck the Permits box from the data sets or

change the Data View to US Wells.

To view permits only, uncheck the Producing Wells and Non-Producing Wells boxes and check the

Permits box only.

For example, if you are interested in BOTH Well Performance Data for producing wells and Permit Data,

you would select the Producing Wells and Permits data sets, as seen below:((insert PNG))

*Special note about querying for both Producing Wells and Permit Data:

When Querying for both Producing Wells and Permits, selecting a common data element will limit your

selection in both datasets.

For example, say you want to see Operator XYZ’s producing wells and all permits filed since January 2015,

then plot them on the Map. By selecting Operator XYZ, your permit results will be restricted to Operator

XYZ. The workaround for this is to select all operators, then narrow down by State and County where

25

Operator XYZ is active, and then select Permits filed since “January 2015.” View the map and then color

code the well spots for Operator XYZ. This will provide the visualization that you are looking for.

The total counts shown on the Select Filter Value window in the U.S. Wells and Permits data views show

all wells, as counted -- Producing, Non-Producing and Permits. This count will be higher than the actual

result. Press the Test button to view the true query results which contain the correct counts.
