Patent number: 6209663Abstract: Apparatus and methods for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure.Type: GrantFiled: April 14, 1999Date of Patent: April 3, 2001Inventor: David G.

Patent number: 6138778Abstract: The present invention is a low differential pressure relief valve made up of a valve body and an elastic membrane for downhole tools, especially rolling cutter drill bits. An aperture is formed in the membrane and a valve body with protruding end stops is mounted in the aperture. The thickness and shape of the valve body are such that the aperture is stretched when assembled. The amount the membrane is stretched and the geometry of the protruding end stop, control the differential relief pressure. The valve body and each end stop can be designed so that the pressure relief setting will be different, depending upon which side of the membrane has the higher pressure. The relief device may be adapted to be integral with existing elastic membrane type lubricant pressure compensation devices for downhole tools.Type: GrantFiled: August 20, 1999Date of Patent: October 31, 2000Assignee: Camco International Inc.Inventors: Randall Ray Price, Walter Scott Dillard
