摘要： The viscosity of heavy oil may be incrementally reduced over what can be achieved by steam alone, by introducing an aqueous metal salt solution into a reservoir undergoing steam injection. The metal ion is selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo and Al. In a preferred feature CO is also introduced as a second additive, with a further oil viscosity reduction being observed with certain of the metal ions.

摘要： The sweep efficiency of a steam drive process is improved and steam override reduced significantly if steam is injected into a formation until channeling has begun, after which steam injection is terminated and a slug of a thermally stable diverting fluid comprising a high molecular weight hydrocarbon within the temperature range of 500.degree. to 1000.degree. F. is injected into the steam-swept zone and allowed to cool until the diverting fluid has increased in viscosity to a value greater than the in place oil thereby creating a highly immobile slug in the steam-swept zone. Thereafter, injection of steam is continued and oil recovered. Multiple cycles of steam injection and rejection of slugs of diverting fluid may be repeated to improve sweep efficiency depending upon the vertical thickness of the formation.

摘要： A method and apparatus for recovering oil from an oil bearing formation utilizing steam injected into the formation. A working fluid is heated at the surface to produce a reversible, chemical reaction, particularly a reforming reaction in a reforming/methanation reaction cycle. The products of the reforming reaction are transported at near ambient temperatures to a downhole heat exchanger through which water is circulated. There a catalyst triggers the methanation reaction, liberating heat energy to convert the water to steam. The products of the methanation reaction are recirculated to the surface to repeat the cycle. In one embodiment the products of the methanation reaction are injected into the formation along with the steam. Various catalysts, and various systems for heating the working fluid are disclosed.

摘要： High viscosity petroleum, such as heavy oils and tar, is recovered by first drilling a number of production wells in a conventional pattern, then drilling a plurality directionally drilled injection wells extending radially inward toward each producing well, such that the surface location of each injection well is not less than the normal spacing between production wells, and the bottom hole location approaches the production well closely enough that fluid communication between the two wells can be established by the injection of heated fluids into the injection well. The petroleum is then recovered from the producing well by conventional thermal means.

摘要： The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injection well and one producing well, with an infill well which is in fluid communication with the bottom half or less of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well; then converting the infill well from a producer to an injector and injecting steam into the lower portion of the formation via the infill well and recovering fluids from the production well. Two separate communication paths are established, one between the surface and the upper half or less of the formation, and one between the bottom half or less of the formation in the producing well, or in the infill well, or injection well, or combination of two or more thereof. A fluid having lower mobility than steam is injected into the upper part of the formation via one or more of the communication means after steam override has begun, to resaturate the steam swept zone with the low mobility fluid to prevent further steam flow therethrough and force steam to flow into unswept portions of the formation.
