... Abstract This paper describes how near real-time tracer data from the onsite tracer analysis enabled the operator in the Nova field to interactively optimize two well clean-ups to the rig. The tracers provided key information on the clean-up progress in different zones which enabled...

.../minute. The total extracted volume is typically in a range of 1 to 10 dm3. Figure 1 illustrates a typical WFT tool. WFT provides some advantages over testing on drill pipe or tubing, both referred to as DST: The deployment is fast, which saves rig time. It provides effective means...

.... Perform the completion process without a rig on location. All elements of the strategy must have this element as a primary consideration. Plan and prepare for the delivery of the completion in a manner that is practical, economic, and timely, so that job quality and safety are not compromised...

... Abstract The continuous improvements in high-speed communications and information technology are transforming traditional drilling working practices. For some services such as data and LWD engineering, personnel no longer need to be physically present at the rig site. New technology guarantees...

...SLIM HOLE PRACTICES ABSTRACT After testing new slim hole drill strings that are able to perform destructive drilling and wireline coring with positive drilling achievement and positive geological data acquisition, the construction of a purpose built rig for slim hole drilling has been...

... wear. The system is completely based on the control of the drill string movement using the drawworks' DC motors and SCR system drive, thus eliminating the need for additional sensors in the derrick. It can be retrofitted to any SCR driven rig at low cost in minimum time. It's application is specially...

... So the possibility of interactions and overlapping of skills (similar skills, consecutive tasks) between roles was analysed in view of optimising the activity of rig site personnel and the utilisation of the equipment. A set of re-organisation proposals has been assembled that may be tailored...

.... Cost reductions were achieved by using a specially equipped mining rig, a simple but adequate drillsite, cementation performed with a Mobil-owned pump truck and running of used and inspected casing. The biggest challenges were to drill 430 m of horizontal section at a vertical depth of only 270 m...

ABSTRACT This paper summarizes the more salient results of an on-going study of elevated jack-up rig durability carried out by the Workgroup Offshore Technology (WOT) of the Delft University of Technology. Significant discoveries, critical in a design or performance analysis, are presented here...

... In the aftermath of several highly publicised events in the North Sea a drilling contractor has taken a fresh look at their safety programme. It was decided to concentrate on making it an employee oriented programme with the key element being commitment from the rig personnel. At the end of 1989 their lost time...

... ABSTRACT Procedures for top-hole drilling should emphasize the maintenance of hydrostatic control of the well. Crew and rig safety, together with environmental protection, are the most important factors used both in the design of drilling procedures and in choosing among alternative drilling...

Overall the project has exceeded budget and programme largely due to delay in completing the conversion of a semi-submersible drilling rig to a production platform. Subsea work has gone remarkably well. The paper comments on these facts and suggests...
