초록 ▼

This invention is method of recovering gas from a gas-bearing subterranean formation in which gas is produced from an upper portion of the formation and a waste gas is injected into a lower portion of the formation to dispose of the waste gas. The waste gas is injected within a 3000 foot (914 m) radial distance from the production of the gas. The injection and production can be carried out using one well or a plurality of wells.

대표청구항 ▼

What we claim is: 1. A method of recovering gas from a gas-bearing subterranean formation comprising: a) producing gas from an upper portion of the formation; and b) injecting a waste gas into a lower portion of the formation to dispose of the waste gas, said waste gas being injected within a 3000 foot (914 m) radial distance from the production of the gas. 2. The method of claim 1 where the production of gas is through one or more production wells and the injection of waste gas is through one or more spaced-apart injection wells. 3. The method of claim 2 wherein each production well is in fluid communication with the upper portion of the formation, and each injection well is in fluid communication with the lower portion of the formation and a substantial portion of the waste gas injected through a selected injection well is stored outside the drainage volume of the production well closest to the selected injection well. 4. The method of claim 2 wherein at least one of the one or more injection wells is a deviated well. 5. The method of claim 1 wherein the steps of producing gas and the injection of waste gas are carried out within one or more wells. 6. The method of claim 1 wherein the produced gas is produced through a production zone of a well and the injection of waste gas is through an injection zone of the well, and the horizontal distance between the top of the injection zone and the bottom of the production zone being at least distance D in which description="In-line Formulae" end="lead"D=h tan θdescription="In-line Formulae" end="tail" where: description="In-line Formulae" end="lead"θ =Arccos [(0.64h2/3/A1/3R 1/3(ky/kh)2/3(I/W) 1/3]description="In-line Formulae" end="tail" h is the vertical distance from the bottom of the production zone to the top of the injection zone; R is a recovery factor for the well drainage volume; A is the drainage area of the well; ky/kh is the ratio of vertical permeability to horizontal permeability of the formation; and I/W is the ratio of waste gas injection rate to produced gas production rate. 7. The method of claim 2 in which one or more production wells are placed in the upper portion of the formation, and one or more injection wells are placed in the lower portion of the formation, with the horizontal displacement between the injection through any one of the injection wells and the production through any one of the production wells being at least a distance D in which description="In-line Formulae" end="lead"D=h tan θdescription="In-line Formulae" end="tail" where: description="In-line Formulae" end="lead"θ =Arccos [(0.64h2/3/R1/3A 1/3(ky/kh)2/3(I/W) 1/3]description="In-line Formulae" end="tail" h is the vertical distance from the bottom of the producing zone of the producing well to the top of the injection zone of the injection well; R is a recovery factor for the well drainage volume; A is the drainage area of the production well; ky/kh is the ratio of vertical permeability to horizontal permeability of the formation; and I/W is the ratio of waste gas injection rate to produced gas production rate. 8.

The method of claim 9 further comprises removing at least part of the acid gas from the natural gas and using the removed acid gas as the source of waste gas for injection into the subterranean formation. 12. The method of claim 9 wherein the acid gas is injected into the formation simultaneously with production of the natural gas from the formation. 13. The method of claim 1 in which the relative permeability of the waste gas is reduced in the region of the formation above injection of the waste gas into the formation by injecting a fluid agent into the formation immediately above the injection of waste gas into the formation. 14. The method of claim 13 wherein the fluid agent is water. 15. The method of claim 13 wherein the fluid agent is foam. 16. The method of claim 1 wherein the viscosity ratio of the injected waste gas to the produced gas (μinj/μdisp ) is greater than 1.05. 17.

The method of claim 23 wherein the horizontal distance between the top of the injection perforations and the bottom of the production perforations is less than 2000 feet (610 m). 25. The method of claim 23 further comprising injecting into the formation between the top of the acid gas injection perforations and the lower end of the production perforations a permeability reducing agent to reduce the relative permeability of the acid gas in the region between the acid gas injection perforations and hydrocarbon production perforations. 26. The method of claim 25 in the permeability-reducing agent is water. 27. The method of claim 25 in the permeability-reducing agent is foam. 28. The method of claim 18 wherein the hydrocarbons are produced into a first well and the acid gas is placed into the lower portion of the formation from a second well. 29.
