Filed:

Dec 16, 1991

Appl. No.:

7/808788

Inventors:

Hong S. Lu - Carrollton TX

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

E21B 4324

US Classification:

166303

Abstract:

A conduction assisted steam flooding process is described where heavy oil is recovered from reservoirs with limited native injectivity and a high water saturated bottom zone. A horizontal well is placed above the water saturated zone. This well is perforated on its top side at selected intervals. An uninsulated tubing having a circumference smaller than the well is inserted therein to its furthest end thereby making a first and second conduit. Steam is injected into the second conduit and formation fluids are removed by the first conduit or tubing until steam communication is established between the two intervals. Once steam communication is established between the intervals, steam injection is ceased and a thermal packer is placed around the tubing so as to form two separated, spaced-apart, perforated intervals. Thereafter, steam is injected into the reservoir via one interval and hydrocarbonaceous fluids are removed at the other interval.

International Classification:

G06F 3/06

Abstract:

A program operation is executed on a memory sub-system. In response to receiving a request to execute a read operation, executing a first program suspend operation to suspend the program operation. In response to a completion of the read operation, a program resume operation is executed to resume execution of the program operation. A delay period is established following execution of the program resume operation during which execution of the program operation is completed. A second program suspend operation is executed following the delay period.

International Classification:

G06F 3/06

Abstract:

A program operation is executed on a memory sub-system. During execution of the program operation, a request to execute a read operation on the memory sub-system is received. In response to receiving the request, a program suspend operation to suspend the program operation is executed. The read operation is executed on the memory sub-system in response to a completion of the program suspend operation. In response to completion of the read operation, a program resume operation is executed. A program suspend delay period is established following execution of the program resume operation during which a subsequent read operation is stored in a queue.
