摘要： A non-polluting additive or spotting fluid which lubricates, releases and/or prevents differentially stuck drill strings and casings in the wellbore of a subterranean well is presented. This additive composition comprises a glycol or glycol ether derived from a long chain epoxide of greater than 3 carbon atoms (preferably greater than 10 carbon atoms); and preferably comprises the reaction product between 2-ethylhexanol and the epoxide of 1-hexadecene. The present invention enhances the lubricity of a drilling fluid to prevent drill string sticking and when utilized as a spotting agent reduces the time required to release a stuck pipe. This invention also helps reduce or prevent foaming. By eliminating the need for traditional oil-based components, the present invention is non-toxic to marine life, biodegradable, environmentally acceptable, easy to prepare, and capable of being disposed of at the drill site without costly disposal procedures.

摘要： A non polluting additive or spotting fluid which releases and/or prevents differentially stuck drill strings and casings in the wellbore of a subterranean well is presented. This additive composition comprises an ester, preferably monohydric alcohol esters of fatty acids in combination with particulate asphalt. A preferred ester is 2-ethylhexanol ester of a tall oil fatty acid. A preferred asphalt is the asphalt described in Patent 5,120,708. Other preferred components in addition to the ester and asphalt include one or more suitable surfactants, suspension agents such as lime (Ca(OH)2), anticaking and grinding agent such as calcium silicate and antigellation agents such as sodium bicarbonate. The present invention enhances the lubricity of a drilling fluid to prevent drill string sticking and when utilized as a spotting agent reduces the time required to release a stuck pipe. By eliminating the need for oil-based components, the present invention is non-toxic to marine life, environmentally acceptable, easy to prepare, and capable of being disposed of at the drill site without costly disposal procedures.

摘要： Neutral electrolytes, relatively neutral electrolytes, metal oxides, metal hydroxides and/or organic exothermic hydration chemicals may be hydrated with water at a controlled location in a subterranean formation to generate sufficient exothermic heat to at least soften and possibly melt and flow bitumen at or near the location. This controlled and localized heating would be useful in drilling through relatively thick bitumen or "tar" beds. In one nonlimiting embodiment the exothermic hydration reaction does not generate appreciable amounts of gas. Alternatively, the exothermic reaction may be used to liberate hydrocarbons from gas hydrates in an embodiment where the evolution of gas is acceptable.

摘要： An oil-based drilling fluid having a polymer latex capable of providing a deformable latex film on at least a portion of a subterranean sand formation has been discovered to inhibit or control fluid loss and act as a sealing agent when used to drill in sand formations for hydrocarbon recovery operations. Typically, the polymer latex is an aqueous suspension of particles formed by emulsion polymerization that is in turn emulsified into a hydrocarbon base fluid. The polymer particles of suitable size precipitate onto the pores of a subterranean sand formation to at least partial seal the formation with a deformable polymer film.

摘要： A water-based drilling fluid having a polymer latex capable of providing a deformable latex film on at least a portion of a subterranean formation has been discovered to provide reduced drilling fluid pressure invasion when used to drill in shale formations for hydrocarbon recovery operations. A precipitating agent such as a silicate or an aluminum complex (e.g. sodium aluminate) is preferably used in conjunction with the polymer. Typically, the water present contains a salt to form a brine, often to saturation, although the invention may be practiced with fresh water. If a salt is employed, it is often helpful to additionally employ a surfactant, such as a betaine, for example.

摘要： The invention concerns a method for determining the particle size distribution (PSD) of bridging agents in fluids, particularly aqueous fluids used in hydrocarbon recovery such as drilling fluids, drill-in fluids, completion fluids, and the like. It was discovered that the PSD could be selectively determined for calcium carbonate as a bridging agent because it auto-fluoresces. The method is reproducible and is not bothered by the presence of other particles such as drill solids which interferes with conventional methods, for instance, light-scattering techniques. The light used to fluoresce the bridging agent may be filtered to a particular frequency if there are other components present that fluoresce. Flow cytometry is another technique that could be used to implement the invention.
摘要翻译：本发明涉及一种用于确定流体中桥连剂的颗粒尺寸分布PSD的方法，特别是用于烃回收的含水流体，例如钻井液，钻入流体，完井液等。已经发现，由于自发荧光，PSD可以选择性地测定碳酸钙作为桥连剂。该方法是可再现的，并且不受其它颗粒例如钻石固体的影响的困扰，这些颗粒干扰常规方法，例如光散射技术。用于荧光桥接剂的光可以被过滤到特定的频率，如果存在荧光的其它成分。流式细胞术是可用于实现本发明的另一种技术。
