Overview

• The vision

• What does ISA99 compliant mean

• The Realtime Drilling Information System

• Future direction

• Questions

But first, a story….


Slide 3


Meet Stevan: CEO of MorePetrol

He is highly competent

He is careful

Stevan has absolutely no idea of the risk he is exposed to

He is a good CEO

He is diligent and runs a

tight ship


Slide 4


Why does he not know the risk?

• Outsources operation of his rigs

• Multiple 3rd parties involved – all interconnected

• Reliant on 3rd party subscription services for data

He cannot define or control the entry or exit points to his company systems

He has no independent source of data with which to verify the integrity of his wells or equipment


Slide 5


Friday 13th January 2013 is a

very bad day for Stevan

At 13:00hrs a virus affects the

control system on a rig

It is shut down for 19 days at a cost of $10m in NPT


Slide 6


At 20:13hrs an inexperienced drilling team fail to control

a kick and it turns into a blowout after the BOP fails

Fortunately no-one is killed, but significant damage to the environment results. MorePetrol never recovers from the damage to it’s reputation


Slide 7


It was for consequences like these that, in 2009, a project was started

to completely redesign the way companies interconnect and share

data on drilling rigs


Slide 8


The vision

Implement a secure architecture for

data capture and remote access

Make data

available to anyone

Vendor neutral single source for all data

Define the entry and exit points - one cable each

Drive the implementation of data standards

WITSML and OPC UA


Slide 9


Business drivers

• Two main drivers:

– Avoid downtime

Avoid drilling downtime due to system fragility

– Learn & Improve

Inability to learn/improve due to lack of visibility of consistent dataset


Slide 10


Fragile and Robust

• Fragile: More things happen than planned

for a given input

• Robust: the system always responds in a

predictable way for any given input

The more complex the system, the more chances there are to introduce fragility


Slide 11


Why Stevan did not know his risks

• No overall design

– Connectivity on rigs evolved organically

• Unmapped connections – extent not known

– Cannot control entry & exit points

• Inappropriate equipment selection

• Inadequate business continuity plans

• No processes in place to maintain protection

– e.g. OS Patching

No design = no control = FRAGILE


Slide 12


Organic design!


Slide 13


What does ISA99 Compliant Mean

• Multi-part standard – not all published yet

• Our focus is System design and security lifecycle – Building in security and robustness from the ground

up

– Balancing the requirements of the CIA triangle - Confidentiality-Integrity-Availability

– Segregating all parties and restricting traffic between them (zones and conduits)

– Making the system easy to support and maintain in operation

People & Organisation are also relavant but not covered here


Slide 14


Approach

• Engineering led approach – multidisciplined team – All skills required together in one location

• Identified 4 key areas to make a robust system – Hardware and supporting infrastructure;

– Network Architecture;

– Interfaces and data mapping; and

– Supportability and business continuity

“Robustification” – Ralph Langner


Slide 15


Hardware and Infrastructure

• Design in resiliance

• Virtualised infrastructure

• Redundant everything

• Can tolerate failure of over 50% of components

Value of resilience is a judgement based on risk and consequence


Slide 16


Realtime Drilling Information

System


Slide 17


The Realtime Drilling Information System (RDIS)

• Sits in the data path between all parties

• Contains converters for multiple industry standards

• Includes secure remote access and visualisation

• Virtual environment

• Integrated technology from multiple vendors

Converted unknown risk into known risk = controllable


Slide 18


Networks and segregation


Slide 19




Slide 20




Slide 21


Important Health and Safety Advice Look at the cute kittens to prevent TDB

(Technical Drawing Blindness)


Slide 22


Interfaces and Data

• All data exchange happens through the RDIS

• WITS, WITSML & OPC


Slide 23


Data Mapping

• Engineering led approach – understand every data point

• Deconstructed every interface

• Reconstructed using standardised mapping

• Old way = 1 interface record changed every time

• New way = pre-configured record for each tool

40,000 points reviewed – 4,000 pre-configured Make the system easy to use


Slide 24


Types of data

• Surface parameters (e.g. BPOS, WOB, STPP)

• MWD/LWD (e.g. Gamma, Resistivity, ECD)

• Mudlogging (e.g. Mudlog object, lithology)

• Condition Monitoring (e.g. power, temp. starts/stops)

• Cuttings re-injection


Slide 25


• 4 tests for each interface:

– Proof of concept test

– Systems integration test

– Commissioning test

– Final acceptance test

• Full replica mobile system

• Travelled to all vendors

Testing


Slide 26


Implementation of WITSML

• Original hope: implement WITSML for everything

• We did implement WITSMLv 1.3.1 non-realtime

• Not practical for realtime data

• Several challenges

– Time zone setting and time synchronization

– Interpretation and use of indexes and maxIndex

– Setting and synchronisation of UIDs

Setting up WITSML is complicated


Slide 27


Support & Maintainability

• All support performed remotely – no new POB

• Some re-training of existing roles at drill site

• All hardware is “pluggable”

• Held a lot of awareness sessions before go-live

• Pro-active monitoring and alerting to 24x7 support team

• Offline development & training system


Slide 28


Current status of RDIS

• Demonstrated system resilience & supportability

• System went live on 24-Nov-2013

• 4th Well now being drilling

• Zero NPT associated with RDIS

• Data mapping now extended to all rigs in same fleet

• Not asset specific – can be installed on any rig

• Architecture now the basis of a new blueprint

• Now being sold as Eigen+Drill


Slide 29


Future direction

• Further research ongoing into the remote management & monitoring aspects

• Now available as a packaged capability to remove the need for IT project – System has been successfully downsized into mobile

racks

– Standardised data mapping to each vendor

• Further Reduce footprint through solid state technology

• Use of OPC UA as an alternative to WITSML


Slide 30


If Stevan had an ISA99 compliant Realtime Drilling Information System…

The virus would not have spread beyond the infected system

He could have employed advanced applications to identify early signs of a kick and poor equipment condition

He would be happier (probably)
