This paper describes the successful delivery of one ultrahigh-rate gas well (more than 250 MMscf/D) completed in a significant gas field offshore Israel with 7-in. In this paper, gravel-pack pore size is evaluated further by use of the permeability of the gravel pack and other methods. A new sizing method is proposed that is based on the effective formation size and the gravel-pack pore size. An operator successfully executed two wireline through-tubing gas-shutoff (GSO) workovers in high-angle openhole-gravel-pack (OHGP) completions to isolate high-gas/oil-ratio (HGOR) zones, resulting in significantly increased oil production.
Faster drilling speeds have become one of the major obsessions of the shale sector in recent years. But since completions represent up to 70% of a new well’s cost, maybe this side of the business needs more attention now. This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
Autonomous Inflow Control Valve technology demonstrates significant benefits within first year. Saudi Arabia offers a seemingly bottomless supply of oil and an equally deep array of exploration challenges as well. The most recent hydrocarbon production boom is under way in the Middle East, and this time, the race is spilling into offshore waters. Landmark deal called most significant since 1979 peace treaty. This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
Don't miss the opportunity to hear from the ICoTA Intervention Technology Award finalists in a special Global webinar event! Sign up here to attend the webinar on 2 July 2020 at 0900 hours. The SPE/ICoTA Well Intervention Conference and Exhibition will take place next year 23–24 March 2021 in The Woodlands, Texas, USA. This conference is one of the most popular industry events and brings together thousands of E&P professionals and experts to learn, exchange knowledge, and network.
Mature oil and gas wells will underperform due to different damage mechanisms and/or low permeability, and the unconventional oil and gas wells could not produce at economical rates unless stimulated successfully. The key is to understand and identify the damage mechanism and sources of low productivity in both conventional and unconventional reservoirs, and then to design economical and successful stimulation treatments. In this course, participants will first learn the fundamental science related to geosciences, rock mechanics, and fluid mechanics, and then gain know-how knowledge on the principles of well stimulations followed by practical skills related to design and evaluation of stimulation treatments. At the end of this course, participants will gain the ability and confidence in solving real-world problems by integrating physics, geology, rock mechanics, formation evaluation, production and reservoir engineering. Examples, case studies, and leading software demonstration/practices will further enhance participants' knowledge and skills acquired in this course.
A significant portion of Asia Pacific's hydrocarbon production comes from poorly consolidated sandstone reservoirs which requires some form of sand control implementation for economic production. The expertise and engineering surrounding Sand Control completion designs and optimisation however has not kept pace with the region's needs. The course introduces the participants to the causes of sand production, its impact on hydrocarbon production and the selection of an optimised design to develop the reservoir. The course details the evaluation of the reservoirs' properties including geomechanical, particle size distribution and development objectives to aid in the selection and design of a robust sand control methodology for implementation. The Sand Control methods covered include deferred sand control, perforating for sand control, sand exclusion techniques; screen only completion, cased hole and open hole gravel packing and fracpacks for new reservoirs as well as remedial and retrofit applications for existing wells.
