摘要： Recovery of hydrocarbon fluid from low permeability sources enhanced by introduction of a treating fluid is described. The treating fluid may include one or more constituent ingredients designed to cause displacement of hydrocarbon via imbibition. The constituent ingredients may be determined based on estimates of formation wettability. Further, contact angle may be used to determine wettability. Types and concentrations of constituent ingredients such as surfactants may be determined for achieving the enhanced recovery of hydrocarbons. The selection can be based on imbibition testing on material that has been disaggregated from the source formation.

摘要： A method is given for treating a wellbore to increase the production of hydrocarbons from a subterranean formation penetrated by a wellbore, involving a period of injecting into the formation an aqueous injection fluid having a different chemical potential than the aqueous fluid in the formation. If there is water blocking, an osmotic gradient is deliberately created to cause flow of water into the injected fluid; hydrocarbon is then produced by imbibition. If the pore pressure in the water-containing pores in the formation is too low, an osmotic gradient is deliberately created so that water flows from the injected fluid into the water-containing pores, increasing the pore pressure and facilitating hydrocarbon production by imbibition. The method may be repeated cyclically. A semipermeable membrane may be created to enhance the osmosis. Wetting agents may be used to influence imbibition.

摘要： The present Invention relates to method to stimulate the production of hydrocarbons from a subterranean formation. In particular, the present Invention discloses and claims methods to enhance the removal of fracturing fluid from a fracture deliberately created in the formation, thereby increasing effective fracture length, and thereby increasing hydrocarbon production. The methods of the present Invention involve breaker schedules opposite conventional teaching—i.e., according to the Invention, the breakers are staged such that the fluid near the fracture tip breaks first creating a viscosity gradient which causes the fluid resident in the tip to move towards the wellbore where it is more easily removed. Preferred embodiments of the Invention involve the use of gas to foam the fluid in the early pumping stages to induce a density gradient, as well as the use of fibrous material in the latter pumping stages to stabilize the proppant pack as the energized fluid in the near-tip squeezes through the near wellbore region.
摘要翻译：本发明涉及刺激从地层形成烃的方法。特别地，本发明公开并要求提高从地层故意产生的裂缝中去除压裂液的方法，从而增加有效的裂缝长度，从而增加碳氢化合物产量。本发明的方法涉及与传统教学相反的断路器时间表，即根据本发明，断路器被分级，使得破裂尖端附近的流体首先破裂，产生粘度梯度，这导致驻留在尖端中的流体向着井筒更易于拆除。本发明的优选实施方案涉及使用气体在早期泵送阶段中使流体发泡以引起密度梯度，以及在后一个泵送阶段中使用纤维材料以将支撑剂包作为近端的通电流体 -tip挤压穿过近井身区域。
