A gravel packing method and apparatus are described where to set the packer; a ball is dropped to a seat that it isolated from the effects of formation pressures when trying to set the packer. This is accomplished by isolation of the gravel pack outlet port when setting the packer and locating the ball seat in a position where the effects of formation pressure are …
Sand production is one of the main problems restricting the safe, efficient and sustainable exploitation of marine natural gas hydrate. To explore the sand-control effects of gravel packing, experiments that simulate …
A method of gravel-packing an oil well. It applies to wells that have high formation pressure so that weighted drilling mud was required in order to contain the pressure during drilling. The method uses a slotted liner and washpipe combination attached to the end of a tubing string. It involves first circulating out the drilling mud while holding back pressure to …

Fig. 1illustrates typical gravel packs for cased and openhole completions. These employ crossover gravel packing equipment that is state-of-the-art in the industry today. Washdown and reverse circulation methods are other alternatives that are less expensive and are to be used when costs will not support …
Abstract. Gravel packing can be successfully performed on high-angle wells (70/sup 0/-80/sup 0/) when special consideration is given to the completion design and details of field procedures and practices. Through analysis and modification of current techniques and research done on full scale models, Chevron experimented with and developed ...
