Core.Petrophysics depends on access to many types of data, particularly log and core together.
A wide choice of tools are available for bringing the core data into the interpretation including plotting, editing, upscaling, classifying and fi tting function defi nition. All of these can be found in the application modules Techcore (Tco), Saturation-height modelling (SHM), and CoreDB (CDB).
Core data storage and manipulation are vital tasks. Once they are properly managed, the effective integration of core data with other sources requires reconciliation for reasons of differences in measurement scale and measurement environments. Integration and reconciliation are facilitated by visualisation, quantifi cation and upscaling.
Log.Log data are the fundamental data resources available to petrophysicists. Now, the term includes a wide variety of data types and modes of acquisition: Wireline, LWD, continuous recording, irregularly sampled, single value at a sample, multiple values at a sample (array data), image data, real-time data streaming.
Day after day petrophysicists and log specialists are loading, manipulating and analysing large quantities of log data. Experts go further with specialised interpretations addressing advanced petrophysical questions.
Find these activities in the following modules: Quanti (Q), Quanti.min (Q.m), NMR, Thin bed analysis (TBA) and Saturation-height modelling (SHM)

Fluids.Reservoir layering, continuity and compartmentalisation are key elements of detailed reservoir characterisation. Their effective analysis is enhanced by bringing many different strands of data to bear on the problem. You can do this within Techlog© where the FPress (FP°) and Fluid Contact (Fc) modules evaluate multiple contacts within compartmentalised reservoirs to derive minimum, maximum and most likely depths for fl uid contacts in complex reservoirs.
The resultant contact surfaces and fl uid typing, by compartment, can be visualised in 3D and instantly updated, should analyses change.
Geology.In addition to the well-by-well view, you can post data onto maps, see the well spatial relationships in 2D/3D and assess correlations and trends qualitatively and quantitatively through the subsurface. Primary tools in the geological workfl ows include log data for correlation and geological characterisation, core data for facies descriptions and image data for structural and fracture analysis.
Core and log data are used very effectively together within Ipsom (Ips) for example to characterise facies; borehole image interpretation in all its forms is the main activity covered by the Wellbore imaging (Wbi) module.

Earth Model.Show petrophysical and geological data and results as a 3D view of the sub-surface within the same environment where detailed interpretation of those data are performed.
Access the 3D graphical library of 3D Vue (3DV) to build a visualisation of an “Earth Model” which you can then use to explore the interwell space. The 3D graphics toolkit is also used within Wellbore imaging (Wbi) to represent image data and dip planes.
Now petrophysicists work within the context of the full reservoir view in Techlog©.
Geophysics.The need to tie seismic survey data into well information is paramount in successful seismic analysis. Well data are often considered the “ground-truth” for seismic data.
Preparation of the log data is best done within the log domain using the neural network in K.mod (K.m); thus, in Techlog© you can use Geophy (GeΦ) a comprehensive, single-offset, synthetic seismogram package that includes time-depth functioning from checkshot and/or sonic log data, fl uid substitution and synthetics fi ltering.
Then compare these and other petrophysical results directly against seismic data (loaded from SEG-Y).

Data handling.
Rapid and effective organisation of data is paramount. Understand the data that are present, understand their limitations, plan the steps required to repair data and then carry out those repairs on large amounts of data at once, either through detailed query commands or through graphical tools.
Within a Techlog project there can exist one or more wells, each with one or more datasets, each with one or more variables. There are no software limitations to the storage.
Make sense of what can amount to very large quantities and variety of data through data tools such as inventories for each data type in the project.
Search for and repair erroneous naming or unit assignment; ensure the correct family and/or alias attribution is made. By this means, performing multiple well data processing becomes very effi cient in the system.
Datasets hold data at a single reference, which can be regular, irregular, depth (MD, TVD, TVDSS, etc.) or time-based, or just a simple index count (e.g. sample ID for core data).
Images and complex array data curves are stored within the same robust data model.
Data Management
When simple editing is not suffi cient, turn on the power of the many graphical and calculation-based tools for more complex data processing.
Data can be re-sampled, shifted, despiked, clipped or upscaled.
Perform mathematical operations such as fi nd derivatives, integrate, fi lter, spline or linearly interpolate or standardise. Frequency domain fi ltering is a powerful option in this category of tool.
Multiple wells may require inter-well normalisation, for instance before computing formation properties. Ensure full and close user control of this operation with a graphical interface to view progress and results at all times.
Data Processing
Data inventory and query
Inspection and review of the values or content of simple curves, arrays, zonations and well properties are facilitated by dedicated spreadsheet-type editors. These can often be linked or copied directly into ExcelTM
for reporting or sharing data with colleagues.
Combine, re-size datasets within wells or merge data from several wells into a composite well as the process may require.

Viewers.
There is an enormous range of customisable and interactive viewers that you can use to look at your data. All plots can be conditioned by depth or zone ranges to focus your views to the matter in hand. Once a plot is made for one well, apply it to many other wells directly, or after storage. Run previous templates again by the double-click. Rapidly build matrix plots of histograms, cross-plots, box-plots to see cross-relationships between many data simultaneously. Data selected in plots are instantly identifi ed in all other plots that share a common reference.
All aspects of the plots are customisable; freely mix regular and irregular sampled data; drag & drop arrays and images onto the plot and easily add log or core data on top; vary the scale factors of tracks to amplify sections, or look in detail at core photos; create cross-plots and histograms on the plot that can be live with the data in the display and updated by dragging up and down the plot; add colours and shadings to custom designs or choose the built-in templates.
Customisable
Box-plots, histograms and cross-plots allow you to take data out of the depth domain; in one dimension look at CDFs and PDFs across one or more wells; in two dimensions explore relationships with fi t lines, fi xed or free; see the actual data plotting or the frequency density distribution, that is such an aid to picking end points in analyses; choose subsets of data and calculate instantly the fi t lines through the restricted data; see your data choice highlighted in all other viewers using the same reference system.
Broad and interactive
In Techlog©, graphical tools are more than cosmetic “add-ons” to the system. Intelligent use of plot structure and colours make the pictures a truly integrated part of
the solution process, facilitating complete incorporation of all data types within the many plot options available.

User programming.
PythonTM is an open-source scripting language that has been harnessed to work inside Techlog©. You can use the full power of the Python language; for example you can customise integrated workfl ows or generate data access routines that link directly into Oracle® databases. It is powerful, yet can be incredibly simple.
Within the platform, there is an editor/parser environment for the PythonTM language together with libraries of access-functions to the data, plot objects and the calculations under the hood in Techlog©.
There is no need to maintain a dedicated compiler for the language, which keeps installation very simple and managed entirely within the Techlog program.
Comprehensive
Tap into the brainpower of thousands of developers and practitioners in PythonTM, from all over the world, to make your special application that accesses the Techlog© data and plot objects that much more effi cient.
Be effective with a few lines of program that yet can be run on multiple wells and multiple zones without the user having to program a lot of housekeeping code to make it happen.
Short learning curve
Python scripts permit the automation of many tasks; for example, establish a batch process that periodically reads a real-time data stream and automatically processes a set analysis workfl ow to produce a preformatted output product.

Statistical analysis.
There are many statistical analysis techniques available for obtaining a different insight into your data. Looking at data “shape”, data “structure”, looking for data patterns, every analyst knows that these are extremely important tasks. In the Techlog© platform these are aided by the GUI and the inter-process interactivity.
Create tables of simple exploratory statistics that cut through the data in many different ways. Easily produce reports and synthesise large volumes of data. For fi nal output archiving or compilation,
directly transfer the reports into ExcelTM or into the plot header/footer region of the output product.
Calculation of statistics on histograms and in the Data editor further facilitate this
important means of data characterisation.
Access multiple linear regression for a quick look at multivariate trends in your data.
The basics
Increasing in sophistication, use different techniques of Factor analysis to make choices amongst input data when preparing specialised neural network models for classifi cation and function building.
Another more frequent task is to perform data reduction and correlation analysis to assess importance amongst input data.
Make use of the new Decision Tree analysis tool for building classifi cation rule sets.
Factors
Correspondence analysis allows you to compare descriptive data class assignments in an objective manner.
For instance, measure the performance of your facies prediction results.
Correspondences

• Using the clay-bound water (CBW) cut-off (from constant or curve), the NMR clay-corrected porosity and the CBW volume are computed. The Free-Fluid-Index (FFI) cut-off is used to compute the hydrocarbon volume. The total porosity is an integration of the regularised T2 distribution
• Two estimates of permeability, the Coates and SDR permeability, are automatically computed from standard equations whose parameters can be again curves or constants and can be adjusted graphically if necessary

Ipsom.The intelligent classifi er
Advanced classifi cation technique Comprehensive statistical tools
Automatic facies identifi cation is playing a key role within the Oil & Gas industry. Ipsom (Ips) is a unique classifi cation module that brings added value to interpretation workfl ows.
The 2D indexed and probabilised self-organizing map (Ipsom) is designed for use in:
• geological interpretation of well log data and facies prediction
• optimal derivation of petrophysical properties (Ф, K, hydraulic units etc.).
During the fi nal control and validation phase, results are quantifi ed and refi ned through an iterative process. High quality statistical and graphic tools with total interactivity and great ease of use, lead to a better
understanding of coherence between core description, log responses and consistency on the map.
Self-Organising Map at initialisation phase
Sorting and organisation phase of the grid of nodes
Indexation phase with facies core description
Accurate model calibration Outputs
The key to the classifi cation process is calibration. The aim of calibration is to give each neural unit an actual geological meaning: this is known as the indexation phase. Each neural unit is assigned a code that
corresponds to a geological interpretation (detailed core description). This stage is essential for a direct interpretation of electro-facies in sedimentological terms.
Optimised partition of log • data calibrated to facies described in core

K.modObjective reconstruction of missing data
Supervised Neural Networks
Parameters can be • reconstructed or modelled directly from log data, via an interactive learning process
Multi-Layer Perceptron: • a powerful non-linear modelling tool that retains all the original variability in the data
Quantitative parameter modelling
K.mod (K.m) is designed to extract essential information from log data in order to:
• predict non-recorded parameters (Ф,K)
• reconstruct missing or poor quality measurements and therefore compensate for bad hole conditions, environmental effects, acquisition problems, etc.
• bring solutions for scale shift management from core to reservoir scale
• potentially reduce the need for coring and plug analysis for the subsequent appraisal wells by comparing well log and core data
Network design diagram Progression of error minimisation Default output layout showing fi t quality assessment in right-hand track: permeability example
Interactive, easy-to-use and very fastFully quantifi ed uncertainties
• K.mod (K.m) is based on a complex technology but remains easy-to-use
• It is a straightforward but effi cient tool that offers a simple interpretation and a more accurate reservoir characterisation
K.mod (K.m) is not a “black box” tool: the users keep full control of the input parameters and receive clear feedback on the log quality and model quality, at all times.
Uncertainties can be managed:
on inputs: back propagation • method to check the contribution of each input
on output: self-organised map is • categorising data samples in the training and validation data for their effectiveness in modelling the target data
Possibility to weight inputs to force the model to reach extreme values.
Optionally standardise output and learning data distributions to match dynamic ranges.

Techdata.Data management
Data management is all about data harmonisation for effi ciency of access. Multi-well capability is built-in from the ground up. Powerful tools are available in Techlog© with which to identify the data that are present, to understand any naming or unit problems, to correct those issues rapidly in order to arrive at a state where access to 1000 wells’ data is as straightforward as access to two wells’ data.
Techlog easily handles regular or irregular depth or time reference systems simultaneously.
The simple principles of a “Data Family” or a “Data Alias” allow you to rapidly harmonise names, units, scales, colours etc. across your entire project,
and allow you automatically to control preferential data selection
Clarity
From potentially many hundreds of wells in a project, use powerful data mining tools to rapidly understand the data that are present and any
errors of naming, units and families assignment, etc.
Using the combination of data inventories and detailed data queries, search, fi nd and repair spurious names, units and family/alias assignment.
Arrive at fully harmonised datasets ready for effi cient multi-well work in a fraction of the time.

PythonTM
Go further with user programming
Introduction
PythonTM is an open-source scripting language that Techsia has incorporated within the Techlog© platform. In the world at large, it is in use today across many industries; it is being developed by many individuals to perform all manner of programming activities from simple calculations to complex interface and database implementations. When you use Python in Techlog, you have available an enormous resource of technology that is derived from a user-base numbered in the many thousands.
What Techlog© provides
Techlog© PythonTM editor combined with “libraries” that permit access to:
All Techlog data objects • (e.g. wells, datasets, curves, properties etc.)
Maths/Statistics routines•
Petrophysical calculations • (e.g. shale, porosity and saturation equations)
Plot objects (e.g. access • a pre-defi ned template or create a new template within a Python script)
PythonTM script editor: example of data manipulation with interactive help
More resources How to use it
Additional tools and library • functions through Internet access from the PythonTM community
Scripts can be used to access • previously compiled code written in C++ or Fortran, for example
• Techsia has provided a large number of ready-made scripts that accomplish many tasks; these can be used as completed, functioning scripts or as starting points for adaptation to a specifi c task of interest
• Scripts can be run “stand-alone” directly from the Python editor; any script can access other scripts as “sub-routines”
• Scripts can be incorporated into Quanti (Q) workfl ows and thus be applicable over many wells and/or data interval ranges without the analyst having to write a lot of data access/housekeeping code
Qvn calculation: PythonTM script within a Quanti (Q) workfl ow table and output display in the layout

Techstat.Comprehensive exploratory data analysis
Classifi cation and normalisation Regressions
Hierarchical clustering:
• fi nd similarities between wells
• group wells together
• if necessary, align data responses using sophisticated Gaussian analysis, group-by-group amongst wells
• results are displayed in a dendrogram
Decision Tree:
• powerful classifi ers where inputs are mixed and incomplete variables (qualitative and quantitative)
• rank inputs by their information gain
• deduced rules can help to understand the input data
Linear (RMA, Major Axis, x/y, y/x), • non-linear, polynomial algorithms are available
Regression and other fi t lines and • functions may be created and conditioned on fi lters, zonation, well-by-well or multi-well
Fit lines may be calculated for • user-defi ned subsets of data using the data selection tools and interactivity between viewers
Regressions can be freely • calculated or forced through a fi xed point on a plot
Input user defi ned-equations • graphically and by keyboard entry
Hierarchical cluster analysis (HCA) dendrogram
Decision Tree rules
Regressions by selections and table of resulting
equations for reporting
Factor analysis Coming soon
• Principal Component Analysis (PCA) is a useful tool to summarise data, since it separates the dominating features in the dataset
• Linear Discriminant Analysis (LDA) is used to determine the best projection space to discriminate between two or more naturally occurring groups. It clarifi es subsequent cluster analyses on users’ data
• Multiple Correspondence Analysis compares qualitative variables that may either be of similar type (observed vs predicted curves) or be of dissimilar type (geology vs petrophysics)
Extend the reporting of • exploratory statistics with a new and comprehensive reporting module. Partition your wells by zones or facies or fl uid types, for example, and select from many summary statistics
Build P10, P50, P90 output • reports for sharing with colleagues
Analyse uncertainties in • zone summary information with Monte Carlo analysis of results tables
