摘要： Improved method and system for accessing subterranean deposits from the surface that substantially eliminates or reduces the disadvantages and problems associated with previous systems and methods. In particular, the present invention provides an articulated well with a drainage pattern that intersects a horizontal cavity well. The drainage patterns provide access to a large subterranean area from the surface while the vertical cavity well allows entrained water, hydrocarbons, and other deposits to be efficiently removed and/or produced.

摘要： A method of drilling sub-sea oil and gas production wells in which a liquid hydrocarbon substance, such as a natural gas liquid, is injected into the drilling mud supplied to the well in order to reduce the mud density. The method of the present invention enables reduction and control of the hydraulic pressure of the drilling mud while drilling production wells in deep water, thereby to require fewer casing runs which eventually yields better oil productivity.

摘要： A well, such as a natural gas well, may be treated to increase production of gas by inserting into the tubing string a water soluble carrier containing a well treating chemical adapted to aerate fluids standing in the tubing string. The dissolvable carrier contains a compressed swab adapted, upon dissolution of the carrier, to expand to fill the diameter of the tubing string, and well treating chemicals adapted to aerate the standing fluid in the well above and below the swab. The presence of the aerating fluids in the well lighten the hydrostatic head, permitting a plug of fluid above the swab to be displaced from the well as the swab is urged upward due to pressure exerted on the swab by the formation and by the aerating effect of well treating chemicals released below the swab. The dissolvable materials for the carrier preferably are selected so that the carrier will not dissolve until it has reached a seating nipple near the lower end of the tubing string, thus assuring that the maximum slug of fluid is displaced from the well bore above the swab.
摘要翻译：可以处理诸如天然气井之类的井，以通过将含有适用于使位于油管柱中的流体充气的良好处理化学品的水溶性载体插入油管柱来增加气体的产生。可溶解的载体包含压缩的拭子，其在载体溶解时适应膨胀以填充管柱的直径，以及良好地处理适于使拭子中的上方和下方的立方流体充气的化学物质。在充分减轻静水压头的情况下，充气流体的存在可以减轻静水压头，使得拭子上方的液体塞从井中移位，因为拭子被向上推动，这是由于通过地层施加在拭子上的压力以及曝气效果良好地处理在拭子下方释放的化学物质。用于载体的可溶解材料优选地被选择为使得载体在其到达管柱下端附近的止动接头之前不会溶解，从而确保流体的最大块塞从拭子上方的井眼位移。

摘要： Improved methods of generating gas in and foaming aqueous well fluids introduced into a subterranean zone are provided. A method of the invention includes the steps of combining with an alkaline aqueous well fluid one or more gas generating chemicals and a mixture of foaming and foaming stabilizing surfactants so that the gas generating chemical or chemicals react with the alkaline aqueous well fluid and gas and foam are formed in the well fluid while it is being pumped, and then pumping the well fluid into the subterranean zone.

摘要： A method for controlling a subsea well that includes shutting at least one blowout preventer, opening at least one isolation line, and circulating an influx out of a well while an inlet pressure of a subsea mudlift pump is adjusted to maintain a substantially constant drill pipe pressure at an initial circulating pressure. After the influx is circulated out of the well, drilling mud with a kill mud weight is pumped into the well. The drill pipe pressure is reduced according to a preselected drill pipe pressure decline schedule until the kill mud weight drilling mud reaches the bottom of the well. The drill pipe pressure is then maintained at a final circulating pressure by adjusting the inlet pressure of the subsea mudlift pump. The kill mud weight drilling mud is then circulated from the well bottom to the surface at the final circulating pressure.

摘要： A process for circulating an aqueous foam in a wellbore includes the steps of forming a foam from an aqueous composition having a determined pH value, injecting the foam into a well so that it circulates from the surface to the well bottom and then back from the well bottom to the surface, and then changing the pH value of the foam when it returns to the surface. The aqueous composition from which the foam is made includes at least one ionic surfactant whose charge does not practically depend on the pH value and a polyampholytic polymer whose global charge depends on the pH value. This composition gives the foam the property that when the pH of the foam is varied at the surface of the well, the charge of the polyampholytic polymer is modified and the foam becomes destabilized and breaks more readily.
