| 20100126716 | Actuator For Downhole Tools - An apparatus, method, and system for actuating a wellbore tool includes a body having a chamber in which a movable member is disposed. The movable member may connect to a selected wellbore tool. Within the chamber is a controllable fluid that substantially prevents relative movement between the body and the movable member when exposed to an applied magnetic field. A generator applies the magnetic field to the fluid and may change the applied magnetic field in response to a first control signal to release the movable member from the body. A driver displaces the movable member relative to the body once the movable member is released from the body. | 05-27-2010 |
| 20100132957 | DOWNHOLE SHAPE MEMORY ALLOY ACTUATOR AND METHOD - A downhole actuator includes, a sleeve, a mandrel, and at least one of the sleeve and the mandrel is in operable communication with a downhole tool to be actuated. The actuator further includes, a follower disposed at one of the sleeve and the mandrel, a pathway disposed at the other of the sleeve and the mandrel, the pathway being receptive to the follower and configured to cause rotational motion and limit a stroke length between the sleeve and the mandrel in response to longitudinal motion between the follower and the pathway. The actuator also has a shape memory alloy in operable communication with the sleeve and the mandrel configured to longitudinally move the sleeve in relation to the mandrel in response to temperature changes thereof. | 06-03-2010 |
| 20110000547 | TUBULAR VALVING SYSTEM AND METHOD - A tubular valving system includes, a tubular having a bore therethrough with at least one port defining fluidic communication between the bore and an outside of the tubular, and a valve stem disposed within the bore of the tubular that is longitudinally movable with respect to the tubular, the valve stem has an outer surface slidably engagable with the bore, the outer surface has features that provide variably choked fluidic communication between the bore and the at least one port, and an amount of choke varies depending upon a relative position of the valve stem with respect to the bore | 01-06-2011 |
| 20110000660 | MODULAR VALVE BODY AND METHOD OF MAKING - A modular valve body includes, a tubular defining an inner bore extending longitudinally therethrough and the tubular has standardized fittings at both ends that are connectable to a drillstring or tubing. The body further has a first surface disposed at the tubular that is in fluidic communication with the inner bore by at least one port, the first surface is receptive to any one of a plurality of selectable modular valves mountable thereat, and a second surface disposed at the tubular is receptive to a circuit configurable to control the selected one of the plurality of selectable modular valves. | 01-06-2011 |
| 20110000674 | REMOTELY CONTROLLABLE MANIFOLD - A downhole manifold configured to manage fluid flow to or from a subterranean formation including a housing in operable communication with two or more fluid pathways and having one or more ports for fluid communication with a flow channel; and a valve stem disposed within the housing and actuable to fluidly select one of the two or more fluid pathways and to fluidly communicate that pathway with the one or more ports. | 01-06-2011 |
| 20110000679 | TUBULAR VALVE SYSTEM AND METHOD - A tubular valve system includes, a tubular, a primary valve actuatable to control occlusion of at least one port fluidically connecting an inner bore of the tubular with an outside of the tubular, and a contingency valve actuatable to control occlusion of at least one port fluidically connecting the inner bore with the outside of the tubular. | 01-06-2011 |
| 20110146265 | Actuator and Method of Actuating - An actuator includes, a housing, an expandable member housed within the housing configured to expand and contract, an elongated member in operable communication with the expandable member, and a ratchet in operable communication with at least one of the expandable member and the elongated member. The ratchet is configured to allow movement of the elongated member in a first direction relative to the housing in response to expansion of the expandable member and to prevent movement of the elongated member in a second direction in response to contraction of the expandable member until the elongated member has moved a selected dimension, after which the ratchet automatically permits movement of the elongated member in the second direction. | 06-23-2011 |
| 20110232765 | VALVING DEVICE AND METHOD - A valving device includes a body having a bore hole and a slot, the slot providing fluidic communication between the bore hole and an outside of the body. A cylinder is rotationally movably engaged within the bore hole and has an opening providing fluidic communication between an outer radial surface of the cylinder and a cavity therewithin. The valving device is configured to alter a portion of the slot in fluidic communication with the opening. | 09-29-2011 |
| 20120168153 | WATERCUT SENSOR USING REACTIVE MEDIA - An apparatus for estimating a parameter of interest includes a conduit and a reactive media in the conduit. The reactive media interacts with a selected fluid component to control a flow parameter of the conduit. The apparatus also includes at least one sensor responsive to the flow parameter. The apparatus may be used for estimating a water content of a fluid flowing from a subterranean formation. The apparatus may include a flow path configured to convey fluid from the formation. The at least one sensor may be responsive to a pressure change in the flow path caused by interaction of the reactive media with water. | 07-05-2012 |
| 20120312523 | MODULAR CONTROL SYSTEM FOR DOWNHOLE TOOL - A modular control system includes a control module removably attachable to an exterior of a downhole tool. A controlled device, the controlled device providing a function for the downhole tool. The controlled device controlled by the control module. | 12-13-2012 |
| 20140151034 | WATERCUT SENSOR USING REACTIVE MEDIA - An apparatus for estimating a parameter of interest includes a conduit and a reactive media in the conduit. The reactive media interacts with a selected fluid component to control a flow parameter of the conduit. The apparatus also includes at least one sensor responsive to the flow parameter. The apparatus may be used for estimating a water content of a fluid flowing from a subterranean formation. The apparatus may include a flow path configured to convey fluid from the formation. The at least one sensor may be responsive to a pressure change in the flow path caused by interaction of the reactive media with water. | 06-05-2014 |
