20090205825 | METHOD OF LOGGING A WELL USING A THERMAL NEUTRON ABSORBING MATERIAL - A method for determining the location and height of a fracture in a subterranean formation using a neutron emitting logging tool. The method includes obtaining a pre-fracture data set, fracturing the formation with a slurry that includes a proppant doped with a high thermal neutron capture cross-section material, obtaining a post-fracture data set, comparing the pre-fracture data set and the post-fracture data set to determine the location of the proppant, and correlating the location of the proppant to a depth measurement of the borehole to determine the location and height of the fracture.

A second, associated, method employing logging tool count rates and count rate ratios to determine the presence of proppant containing high thermal neutron capture cross section absorbers utilizes a crossplot of count rate versus ratio. Logged intervals containing no proppant will fall on a trend/trendline on the crossplot, whereas logged intervals containing proppant will fall off from this trend/trendline. | 08-20-2009 |
20110001040 | METHODS OF IDENTIFYING HIGH NEUTRON CAPTURE CROSS SECTION DOPED PROPPANT IN INDUCED SUBTERRANEAN FORMATION FRACTURES - Methods for determining the locations/heights of fractures in a subterranean formation use a post-fracture log obtained with a compensated neutron or pulsed neutron logging tool.

This relationship is used to compute count rate from the ratio in intervals of the well possibly containing proppant and which have similar formation and borehole conditions. The count rate computed from the ratio is compared with the observed detector count rate, with proppant indicated from suppression in observed count rate relative to count rate computed from the ratio. | 01-06-2011 |

20110048742 | Downhole Safety Valve Having Flapper and Protected Opening Procedure - A downhole valve has a closure device (e.g., one or more flappers) for closing off the valve. A no-go actuation mechanism protects the flappers from damage. When the flappers are closed, the mechanism prevents a tool from passing into the valve and causing damage to the flappers. Yet, the mechanism may open the valve's flappers when the tool string is forced into the valve. When the valve has successfully opened, then the mechanism moves out of the way of the toolstring so it can pass through the valve. For the mechanically operated valves, operators use a shifting profile in the valve only in the upward direction to return the valve to the closed position. For hydraulic actuated valves, hydraulic pressure may be used or exhausted, depending on the design, to allow the flappers to go closed. Once the flappers have closed, the no-go mechanism is once again realized. | 03-03-2011 |
20120073829 | Fail Safe Regulator for Deep-Set Safety Valve Having Dual Control Lines - A hydraulic control system for a sub-surface safety valve has control lines in hydraulic communication with the valve. A first control line communicates hydraulic pressure to actuate the valve, while the other control line communicates hydraulic pressure to compensate for hydrostatic pressure associated with the first control line. A regulator regulates hydraulic communication between the two control lines. The regulator prevents fluid communication from the first to the balance control line as long as integrity of the second line is maintained. When the second line fails, the safety valve can fail in the open position. In this case, the regulator permits hydraulic pressure to bleed from the first line to the second line. This allows the safety valve to then fail in a closed condition and allows the second line to potentially be recharged if its integrity is regained. | 03-29-2012 |

20090050333 | Dual Control Line System and Method for Operating Surface Controlled Sub-Surface Safety Valve in a Well - A control system for a surface controlled sub-surface safety valve has first and second control lines. The first control line communicates control fluid to the sub-surface safety valve and preferably has a sump and in-line filters. Hydraulic pressure applied to the safety valve with this first control line can open the safety valve. The second control line also communicates control fluid to the sub-surface safety valve and preferably has a sump. A connecting valve is connected between the first and second control lines. The connecting valve allows control fluid to communicate from the first control line to the safety valve but prevents fluid communication from the second control line to the first control line. To open the valve, the second control line is exhausted to a reservoir. The dual control lines provide redundant control of the safety valve and can also be cycled to remove debris from the system. | 02-26-2009 |
20090090518 | DEBRIS BARRIER FOR DOWNHOLE VALVE IN WELL - An apparatus has a housing with an internal passage. When deployed, a barrier positions in an upward direction in an annular space between a sleeve and the housing and folds towards one of its sides to conform to the annular space. When debris collection is desired, operators lift the sleeve with a tool, the barrier rotates down and positions across the internal passage, and the tool releases the sleeve. In this stage, the barrier can collect debris to protect a downhole valve. In further stages, operators open the downhole valve, and flow moves the barrier, cage body, and sleeve together in upward direction. Eventually, the sleeve is biased downward again, and the barrier positions within the annular space by reversibly folding towards its opposing side. In this position, barrier points in a downward direction and folds towards its opposing side to conform to the annular space. | 04-09-2009 |

20100051285 | PASSABLE NO-GO DEVICE FOR DOWNHOLE VALVE - A downhole valve has a flow tube hydraulically actuated to open and close a flapper. The flow tube moved to a first position closes the flapper to restrict flow through the valve. The flow tube moved to a second position opens the flapper. A passable no-go device disposed in the valve permits or restricts mechanical passage through the valve in response to the position of the flow tube. The apparatus has a support and one or more dogs supported in windows of the support and biased by springs. The flow tube in the first position pushes the dogs to an extended position that restricts mechanical passage through valve so that a tool cannot be passed through the valve while the flapper is closed. When the flow tube is in the second position, however, the dogs retract so the tool can be passed through the valve while the flapper is open. | 03-04-2010 |
20120012202 | Irregularly Shaped Flapper Closure and Sealing Surfaces - A flapper valve for a surface controlled, sub-surface safety valve has a seat and a curved flapper. The seat has a seating rim, and the curved flapper has a sealing rim and can pivot relative to the seat. The flapper's sealing rim corresponds in shape to the seating rim. Both rims have lobes disposed outside a circular perimeter. Also, the undulating edges of the rims have corresponding outcroppings and incroppings. When a flow tube moves towards or away from the flapper, the flapper's lobes protect the flapper's sealing rim as the flapper's inside surface engages the moving flow tube. Moreover, the rims can have a groove and a ridge that engage one another when the rims close. | 01-19-2012 |
20120097386 | Downhole Flow Device with Erosion Resistant and Pressure Assisted Metal Seal - A downhole flow device has a sliding and ported sleeves. A seal has a first component on the sliding sleeve and a second component on the ported sleeve. These components engage one another to seal flow through the ports in the ported sleeve. The components move apart to allow fluid flow through the ports. The components are protected from abrasion and flow by virtue of the seal's structure and how it is opened. The sliding sleeve moves hydraulically along an axis of the ported sleeve to reveal successive ports defined along the sleeve's axis. Operation of the device and the seal address both erosion and damage from differential pressure problems. Thus, the seal prevent damage when unloading a differential pressure across it, and abrasive flow does not have the opportunity to impinge on the sealing surfaces to cause erosion. | 04-26-2012 |
