Hydrocarbon preparation system for open hole zonal isolation and control

摘要: A system for enhancing hydrocarbon production in long and deviated subterranean wells. Gravel is placed the annulus between screen liner borehole, together with annular isolation elements. Selective flow control achieved. Sequential or commingled achievable from multiple producing intervals of borehole. differential valve incorporated service string to allow gravel placement across screen-liner sections, separated by elements a continuous one stage operation, thereby reducing time complexity such operations.
