Patent CA-2620344-A1 (CA)
Inventor: SINGHAL ASHOK
IPC: E21B43/00
Filed: 2006-03-09
Abstract: A modified toe-to-heel waterflooding (TTHW) process is provided for recovering oil from a reservoir in an underground formation. After establishing the conventional TTHW waterflood, the process includes placing a chemical blocking agent at the watered out producing toe portion of the horizontal leg of the production well to create a blockage in the producing toe portion and to create a new producing toe portion in an open portion of the horizontal leg adjacent the blockage through which most of the production takes place.  Production is then continued through the new producing toe portion and the open portion of the horizontal leg of the production well. These blocking and producing steps can be continued to progressively block producing toe portions in a direction toward the vertical pilot portion of the production well.

IPC: H03K5/13
Filed: 2007-12-20
Abstract: A dual function serial and parallel data register with integrated program verify functionality. The master and slave latching circuits of the dual function data register can concurrently store two different words of data. In a program verify operation, the master latch stores program data and the slave latch will receive and store read data. Comparison logic in each register stage will compare the data of both latches, and integrate the comparison result to that of the previous register stage. The final single bit result will indicate the presence of at least one bit that has not been programmed. Automatic program inhibit logic in each stage will prevent successfully programmed bits from being re-programmed in each subsequent reprogram cycle. Either data word can be serially clocked out by selectively starting the shift operations on either the low or high active logic level of a clock signal.
