Agenda

• Introduction to Knowledge Systems

• Value and technology

• WITSML case studies

• Real-time center environment

• Summary and conclusions

Who is Knowledge Systems?

• Knowledge Systems is the world’s leading provider of geopressure and geomechanical analysis software and services– Our technology is the most widely used

software for pore pressure estimation, geomechanics and real-time surveillance

– Our consulting team provide office and well site services globally

– 100+ people

Knowledge Systems - technology

• Advanced geomechanics and geopressure

technologies

• Relational database used to store, manage and

share pressure-related data

Drillworks ConnectML Retrieves WITS or WITSML industry standard

data for real-time pore pressure and geomechanical

analysis.

The data browser allows you to:• Retrieves LWD and surface logging data from any

vendor system• Transmits real-time data over the Internet for global

access• Provides quick, easily accessable data using Drillworks

applications

Link pre-drill studies with drilling activity

• Updating pre-drill models in real-time– Improves results– Decreases uncertainty

• Two ways– Synchronous – continuous monitoring and

updating (analyst deployed to rig)– Asynchronous – periodic updates once or

twice a day (remote monitoring)

Reasons to use Drillworks ConnectML

• Reduce non-productive time

• Reduce uncertainty while drilling

• Create a high quality wellbore

Drillworks ConnectML Workflow

WITSML - case study #1 • Deepwater well offshore Trinidad• Significant uncertainty in subsurface

environment• High potential for unscheduled events related to

uncertainty• Need for real-time geomechanics modeling• Operator domain expert is not offshore

deployable resource• Unplanned requirement ~ low budget & short

fuse

WITSML - case study #1

• WITSML used to communicate LWD data from offshore Trinidad

• Received into Knowledge Systems Geostress WBS application in Houston

• Geomechanics expert performed analysis, then transmitted data back to the rigsite analyst

WITSML - case study #2

• LWD Vendor replaced on rig• Scenario typically causes

multitude of data transfer issues

• Requires significant work on both sides to regain connections

• WITSML provided seamless hookup to new vendor

• Did not affect data transfer or remote modeling operations

WITSML - case study #2• Schlumberger installed WITSML v1.2

server

• <10 minutes to reconfigure system– IP Address, User Name, Password,

Configuration for server connection– Configure Drillworks data links to ConnectML– Expert began modeling using real-time data– Expert activated WITSML server to make

interpretation available to rig

RTOC Physical Layout

Real-time center environment

• Provide collaborative atmosphere– Sharing project data among analysts– Distributing information to the

stakeholders

• Connections to all corporate data– OpenWorks, Geoframe, Recall, Finder– Facilitates data gathering and browsing

• Robust interface to rig

All based on web services and WITSML

KSI RTOC Strengths

• Diversified experience on part of team members (drilling operations, MWD/LWD, directional, petrophysics, geomechanics, drilling fluids)

• Have experience with real-time monitoring/surveillance

• Has a reputation for competence in pore pressure, fracture gradient, wellbore stability analysis; has some depth of experience and academic expertise in these areas.

• Has good software tools for PP-FG-WBS analysis

Statoil workflow - before

• Direct connection between engineer and rig

• Isolated from corporate data

• Non-collaborative environment

Statoil workflow - after

• Improved connectivity – WITSML

connections from the rigs

– WITSML connections to corporate data

• Delivers increased collaboration among analysts and stakeholders

Summary and conclusions

• KSI is using WITSML technology everyday in conventional ways– Remote data transfer– Improve collaboration between rig and office

• We are also using WITSML technology in unconventional ways– Connect to corporate databases through a

standard protocol
