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.

摘要： Polymer flooding is an effective means of increasing the sweep efficiency of a displacement process for recovering petroleum from a subterranean, petroleum containing formation; however, most polymers suitable for use in flooding operations hydrolyze or otherwise decompose at temperatures above about 150.degree. F to 200.degree. F, and the temperature of many subterranean petroleum-containing formations is in excess of 150.degree. F-200.degree. F. Polymers may be employed in tertiary recovery in formations whose temperatures are greater than the temperature stability limit of the polymer if the formation temperature is first reduced by introducing an aqueous fluid such as water at a temperature substantially below the temperature limit of the polymer into the formation for a period of time sufficient to reduce the formation temperature to a value at or below the temperature tolerance level of the polymer.

摘要： The invention is a method of recovering hydrocarbons from an underground hydrocarbon formation which comprises drilling and completing at least three substantially parallel horizontal wells to form a substantially triangular well pattern within a hydrocarbon formation. The first well is placed relatively near the top of a hydrocarbon interval and the second and third wells are placed near the bottom of the interval on each side of the first well. A recovery fluid is injected into the formation through the second and third wells and hydrocarbons and other fluids are recovered through the first well.

摘要： A method is disclosed for recovering hydrocarbons from underground formations by a series of sequenced steps, involving (1) injecting steam of a relatively high quality into the formation and (2) about the time of steam breakthrough, reducing the quality of the steam being injected to a quality between about 25% and about 50% while simultaneously increasing the rate of steam injection so as to maintain a constant rate of heat injection into the formation. Optionally, hot water having a temperature between about 120.degree. and 180.degree. F. may be injected following the injection of about 0.5 pore volumes to about 2.5 pore volumes of reduced quality steam.

摘要： Techniques are disclosed for the safe production of shallow heavy oil sands which substantially reduce the probability of surface steam breakthrough. A pattern of injection wells and producing wells are drilled through the overburden into a relatively shallow heavy oil producing zone. Firstly the injection wells and the producing wells are cold produced for a combination of heavy oil and sand by use of a progressive cavity pump or the like. Then steam push-pull is used on both the injectors and producers until heavy oil production becomes uneconomical. Finally, low pressure steam is continuously injected into the injection well and heavy oil continuously produced from the producing wells.

摘要： The disclosed invention is a method of recovering hydrocarbons through parallel horizontal wells by use of steam and water injection. Steam is injected into two parallel horizontal wells to stimulate the formation and then the second horizontal well is converted to a production well. About the time of steam breakthrough at the second well, the steam injection at the first well is converted to water injection, production is suspended from the second well, and steam is injected through the second and third wells. After a suitable period of stimulation time, the third well is converted to a producing well, steam injection is continued through the second well, and water injection is continued through the first well.
