“…1 During the early 1990's, the development of enhanced drilling and fluids technology led to advances in extended reach and horizontal drilling. 2,3 Screen only completions became a favored completion mode for completing in long, openhole soft-rock formations with wells providing the capability to deliver high production rates. 4,5,6 This technique is still being successfully used in West Africa, the North Sea and in the lower-pressured gas sands in the Gulf of Mexico shelf.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractSynergy between the horizontal drilling and openhole completion disciplines is required to deliver a reliable highrate well completion in soft rock formations. This gap has finally been bridged, and the resulting success has allowed it to be considered as a mainstay completion technique in deepwater developments in Brazil. It has shown the same potential for upcoming deepwater developments in West Africa. The technology has also been an enabler for heavy oil developments (API gravity <20 deg, and > 0.934) in Brazil and in the North Sea that otherwise would have been uneconomical.This paper will address where we started, the evolution of technology, and the lessons learned that are being applied to increase the application envelope and the reliability of this completion method. The review will cover advances in openhole drilling techniques that eliminate hole tortuosity, gravel-pack fluids that can reduce rig time and enhance well productivity, and improvements in downhole tools that have capability to reduce risk while reducing completion cycle time. The review will also examine a possible replacement technology.The successes already achieved in light of the recent technological advances will be presented in case histories that will verify the reliability that can now be expected.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractOne technological concept that has been capable of successfully coordinating drilling and completion disciplines is horizontal openhole gravel packing. The synergy required to deliver a reliable high-rate well completion has been evidenced in recent completions, and the successful results have brought about the use of horizontal gravel packing as a mainstay completion technique in deepwater development. The technique has been successfully used in Brazil and has shown the same potential in the upcoming deepwater developments in West Africa. This paper will address how and where the concept was started, how the technology has evolved, and lessons learned that are being applied to increase the application envelope and the reliability of this completion method. The review will cover advances in openhole drilling techniques that eliminate openhole tortuosity, gravel-pack fluids that can reduce rig time and enhance well productivity, and improvements in downhole tools that have or will potentially reduce risk while reducing completion cycle time.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractOperators have found that by integrating drilling and completion techniques, they can develop a highly reliable openhole horizontal gravel-pack completion that can control sand production and produce hydrocarbons at a high-rate. Because of the success of this methodology, it has become a mainstay completion technique in the deepwater developments in Brazil and has shown the same potential for upcoming deepwater developments in West Africa. This paper will discuss the evolution of the integrated concepts, the "lessons learned" that are being used to increase the scope of application, and how new techniques are enhancing reliability for these completions. Specifics include advances that eliminate openhole tortuosity in openhole drilling techniques, new downhole tools that can reduce risk as well as completion cycle time, and improvements in gravel pack fluids.These advances are continuing to push the technological envelope. The new technological benefits are: 1) Reduced completion cycle time, thereby reducing completion cost 2) Reduced formation damage 3) Improved completion reliability throughout the potential life of the well.
