For years, offshore shuttling to accommodate insufficient bed-space hasinvoked a safety risk for offshore workers. A North Sea operator has overcomethis by implementing tools to dramatically change the normal work flow indecision making.
Since 1999, the mudlogging crew on the Ekofisk Platform in the North Sea hasbeen performing well monitoring from the operator's onshore office in Tananger,Norway. The deployment of a fiber optic network in this area of the North Seahas provided the means for a reliable workflow with the benfit of reducedtravel to the rig and improved integration between onshore and offshoreteams.
Building on these experiences, a concept was developed to take a "StepChange In Collaborative Decision Making" by building a completely new OnshoreDrilling Centre (ODC) and real time data monitoring system. Project planningstarted in February 2002 and the center was opened and functional by 6 November2002.
A visualization, telecommunication and data-sharing network and wellmonitoring system has been developed and installed to assist the offshoreoperations on a twenty four hours, seven days a week basis
In addition to reducing offshore travel, the objective of the ODC is toreduce the number of iterations in well trajectory planning, reduce drillingcost, improve geosteering decisions and improve integration between drillingand geology, hence reducing unwanted safety incidents while drilling.
This paper describes the technology, people and processes employed to buildthe ODC. The new work flow in well planning and execution of drilling complexERD and horizontal wells from the ODC is described. Preliminary results fromthese new collaborative work processes will be outlined.
With fibre optic cables from the offshore Ekofisk area to shore, most of therequired basic infrastructure for the ODC was already in place. The fibre opticcables ensures a stable and reliable information source that forms thefoundation for truly remote operations.
Offshore locations not connected to the Ekofisk network can be connected viaavailable microwave or satellite links, so that explorations wells withinapproximately 30 km can use the same network to shore. Drilling and otherrelevant data are being collected, transmitted, replicated and managed usingHalliburton Sperry-Sun's dynamic data management service INSITE.
The implementation team in ConocoPhillips determined that the best locationfor the ODC would be at ConocoPhillios main office in Stavanger on the samefloor as the drilling operations and planning team. Although this choicecreated space constraints for building the facility it was felt that theadvantages of having immediate access to the proper people required whenevercollaborative decision-making needed to take place far outweighed any otherconsiderations. The team members whose inputs to the processes are requiredonly on an as-needed basis could comfortably work on their usual duties andrapidly assemble in the ODC when required.
The decision to locate the ODC at ConocoPhillips premises rather thansending and then managing data at a service company office was made toensure:
Operator - Service company integration
Operator Management buy-in
Ownership of sub-surface data
Muliple users from several asset Teams
A third part coordinator was selected as a neutrale facilitator.
Sense Technology was used to help in facilitating the changes required tothe work processes, and to supervise the technical installation. Amultidisciplinary Team consisting of ConocoPhillips, Sense Technology and theService providers, was set up to examine the changes in the work processes.They looked at in detail the manning and tasks of the various operationalphases in well construction. They examined the tasks that could be movedonshore, producing detailed job descriptions for the effected parties, whichwas then incorporated in the risk analysis for these changes. Contracts werechanged to reflect the changes, and training was provided for both onshore andoffshore parties.
