Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.
This paper presents the characterization and comparison of a metakaolin-based geopolymer as a candidate treatment for remedial operations in oil and gas wells versus conventional state-of-the-art materials.
This paper describes the development of a method of predicting drillstring-friction coefficient during tripping operations that can be used for early warning of stuck pipe.

Exception-based monitoring of real-time data by remote operators can increase operational awareness of drilling crews, which can significantly minimize well-control risks by taking proactive and precise actions. -
This 1-day interactive workshop will examine completion/workover/intervention well-control incidents and explore closely a number of key aspects, including what human factors played a part in the well-control incident.
-
Many of the worst oilfield incidents have been attributable to human factors. Consequently, a corporate well-control manual was refreshed to include human factors in the management of well-control incidents.
-
New long-term contracts between offshore drillers and equipment makers reduce downtime and risks associated with key components, from blowout preventers to risers.
-
The unique properties of deepwater formations pose significant challenges to the capabilities of conventional drilling rigs. Using automated drilling equipment, including MPD, efficiency and cost savings can accompany safety.
-
Developing a well-specific subsea-capping contingency plan involves assessing the feasibility of deploying a capping stack from a floating vessel, determining the weight and stability, and performing dynamic-flow simulations of closing the capping stack outlets.
-
One of the more important aspects of well integrity during drilling operations is early kick detection. Recently, new technologies and re-search have been applied or developed to improve the kick-detection systems and to overcome some of the difficulties.
-
A study using a dynamic multiphase-flow software simulated a rapid-unloading event and determined the gas fraction in the riser annulus and the effect on riser fluid levels.
-
An influx-detection-at-pumps-stop (IDAPS) software was developed to provide early warning of abnormal flowback conditions during connections.
-
This paper presents a new technology and methods that can detect leak locations in a well and illustrate the flow profile of the leak.
