摘要： An apparatus and method for providing a time delay in injection of pressured fluid into a geologic formation. In one aspect the invention is a toe valve activated by fluid pressure that opens ports after a predetermined time interval to allow fluid to pass from a well casing to a formation, providing a time delay before fluid is passed through the ports. This time delay allows multiple valves to be used in the same well casing and providing a focused jetting action to better penetrate a concrete casing lining.

摘要： An actuating mechanism for use in a tool such as a plug used in oil and gas wells. The mechanism being operable under pressure in the well bore to set the plug in a first natural closed state for a pressure under a predetermined pressure range; a second closed state wherein the plug is locked closed regardless of the pressure; and a third open state by increasing the pressure to the predetermined pressure range and holding the pressure in the range for a predetermined time. Electronic and mechanical, dual piston, actuating mechanisms are described as is a method of controlling fluid flow in a well bore using the plug and performing a pressure test against the plug.

摘要： A removable ball seat assembly is disclosed. It features a solid ball seat backed up by segmented dogs pinned to each other and mounted under the ball seat. Upon actuating a downhole tool with fluid pressure applied to a ball on the seat, the pressure is increased and the ball and seat move at a regulated rate. The dogs reach a recess and the ball moves through the seat. Subsequent, larger balls can pass through the seat, with the dogs in the recess, at much smaller pressure drops than the original ball.
