摘要： The invention is a method of recovering hydrocarbons from an underground formation by employing modified 7 spot well patterns which contain six substantially vertical corner wells forming a substantially hexagonal well pattern and six substantially horizontal wells located within the hexagonal well pattern running between each of the vertical corner wells and the center of the well pattern. Preferably, the modified 7 spot pattern will also contain a substantially vertical central well located relatively near the center of the substantially hexagonal well pattern. Another embodiment contains six substantially vertical corner wells forming a substantially hexagonal well pattern, a substantially vertical central well and six sets of three horizontal wells, each set of three horizontal wells forming a substantially Y-shaped pattern.

摘要： The invention uses two vertical wells and a horizotal well located within the underground formation extending between the two vertical wells. A thermal fluid is injected into the formation through the first vertical well. Hydrocarbons and other fluids are produced from the horizontal well through a first perforated interval located near the first vertical well. After depleting this area of the formation, the first perforated interval is closed off and the process is repeated for successively perforated intervals of the horizontal well, all of which are farther from the first vertical well than the preceding perforated intervals.

摘要： The disclosed invention is a method of recovering hydrocarbons by employing a modified 9 spot well pattern which contains a vertical central well, four vertical corner injection wells and four horizontal wells as the side wells in the pattern. The horizontal side wells are aligned on axes perpendicular to the substantially rectangular boundaries of the modified 9 spot well pattern or aligned on the axes between the four corner injection wells.

摘要： A method is disclosed for recovering hydrocarbons from heavy oil and tar sand formations by a series of sequenced steps, wherein the production wells are initially steam stimulated. Thereafter, about 0.6 to about 1.2 pore volumes of steam of a relatively high steam quality are injected into the formation through the injection wells. An additional quantity of steam is then injected wherein the steam quality is decreased to a relatively low quality. Water injection and wet in situ combustion conclude the method.
