摘要: A low drag flotation system for placing screens in horizontal wells is provided which includes a screen exterior to the washpipe be placed sand control, and hydraulically actuated valves trapping air within washpipe. The creates buoyancy force that decreases of pipe string well, allowing it move further down well under its own weight. As result, can longer lengths maximize oil gas production.
