Anatomy of an Operations Decision

Case-1 Environment

• 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

Case-1 Installation

• Baker Hughes Inteq installed WITSML v1.2 server in Port of Spain

• <30 Minutes in BP Houston Offices

– Installed Drillworks ConnectML on client PC

– IP Address, UN, Pass, Configuration for server connection

– Configure Drillworks data links to ConnectML

– Expert begins modeling using real-time data

– Expert activates WITSML server to make interpretation

available to rig

Case-2 Environment

• Deepwater Gulf of Mexico Well

• Narrow PP FP envelope (high risk of influx or losses)

• High potential for pressure related unscheduled events

• Client requested expert synchronous surveillance from

Houston offices

• Replace WITS with WITSML

Case-3 Installation

• Schlumberger installed WITSML v1.2 server

• <10 minutes to reconfigure system

– IP Address, UN, Pass, Configuration for server connection

– Configure Drillworks data links to ConnectML

– Expert ready for modeling using real-time data before first tools

run in hole

Case-4 Environment

• Shelf project in Gulf of Mexico

• Precise casing set requirements due to PP ramp

• Limited rig space for additional personnel

• Economics would not support onsite analyst

• Client requested synchronous remote surveillance

Case-4 Installation

• Schlumberger installed WITSML v1.2 server

– No apparent delay, unknown install time

• <30 minutes to configure WITSML client system

– IP Address, UN, Pass, Configuration for server connection

– Configure Drillworks data links to ConnectML

– Expert ready for modeling

Lessons Learned

• WITSML updates slower than WITS

– Internet time versus direct cable time

• Concurrent use of proprietary system (Riglink, Interact) aids in

monitoring data dead zones

• System is still imperfect, and requires companies to collaborate on

problems

• WITSML must be planned before a project.

– Connections attempted as after thoughts have failed.

Key Accomplishments

• Technology

– Short connect and configure time of <30 minutes

– No special hardware or IT involvement required

– Low cost

– Secure synchronous and asynchronous data

exchange

– Omni-directional, multi-user data movement

– Portable

Key Accomplishments

Operations

– Maximum utilization of bandwidth, data and expertise

– Cross discipline collaboration

– Delivered the right information to the right people, at

the right time

– Better decisions resulting from right time, expert

analysis

Progress?

• Multiple connections with two major service

providers

• Successful test with Halliburton 11/05

• Operators becoming more aggressive in their

insistence on WITSML
