| 20080314582 | TARGETED MEASUREMENTS FOR FORMATION EVALUATION AND RESERVOIR CHARACTERIZATION - A downhole-reconfigurable tool string is utilized to obtain targeted measurements for formation evaluation and reservoir characterization. Tool string hardware and corresponding analysis software are dynamically adjusted to meet specific reservoir description needs identified during or before the logging run with the downhole-reconfigurable tool string. A technique for utilizing the downhole-reconfigurable tool string includes four different steps. The first step includes detecting first order features and identifying second order features. The second step includes enhancing measurements relative to the second order features by reconfiguring tool hardware to extract at least the desired information of the reservoir in terms of its static and dynamic properties, and software focusing to enhance the sensitivity to a particular reservoir attribute. The third step is performing an inversion to reconstruct the reservoir property as accurately as possible. The fourth step is using these properties and the planned production/injection data to recommend suitable monitoring schema. | 12-25-2008 |
| 20090159263 | Device for remotely actuating the safety lock of individual oil pumping apparatus - A device for remotely actuating the safety lock of individual oil pumping apparatuses, (also known as AIB) employed in oil wells for extraction of this fluid. The actuating device or locking device permitting to an AIB operator to remotely actuate a safety lock for locking the entire movement of the AIB, without the need that the operator go upwards the AIB to a zone wherein the safety lock is usually housed. For this purpose the locking device includes an actuator for moving upwardly and downwardly the safety lock. The locking device also including an indicator for indicating the position of the safety lock. | 06-25-2009 |
| 20090159264 | HYDRAULIC SLEEVE VALVE WITH POSITION INDICATION, ALIGNMENT, AND BYPASS - A hydraulic sleeve valve that includes a valve position indication system that provides an indication that the valve has reached a predetermined position, such as, for example, the fully opened or fully closed condition. The hydraulic sleeve valve may include a bypass relief system and may also provide a valve control fluid circulation function to filter or otherwise manipulate the control fluid. | 06-25-2009 |
| 20100230093 | PERFORMANCE OF PERMANENTLY INSTALLED TUBING CONVEYED SEISMIC ARRAYS USING PASSIVE ACOUSTIC ABSORBERS - Methods and apparatus for reducing the impact of guided (or “tube”) waves in permanently installed seismic systems are provided. By utilizing passive acoustic absorbers, the impact of tube waves may be reduced, leading to improved performance of permanently installed seismic systems that are installed onto production tubing when the well is completed. | 09-16-2010 |
| 20110024105 | Multi-zone Screen Isolation System with selective Control - A modular screen system allows connection of screens using couplings that connect the annular space in each module between the screen material and the base pipe. A series of connected screens and couplings feed into a single valve to control the flow through many screens. The valve is preferably located in a coupling and the passages through the coupling or the screen can also accommodate instrumentation to detect, store or transmit well data or flows through the various screen modules. | 02-03-2011 |
| 20110061855 | ELECTRIC OR NATURAL GAS FIRED SMALL FOOTPRINT FRACTURING FLUID BLENDING AND PUMPING EQUIPMENT - Methods and systems for integral storage and blending of the materials used in oilfield operations are disclosed. A modular integrated material blending and storage system includes a first module comprising a storage unit, a second module comprising a liquid additive storage unit and a pump for maintaining pressure at an outlet of the liquid additive storage unit. The system further includes a third module comprising a pre-gel blender. An output of each of the first module, the second module and the third module is located above a blender and gravity directs the contents of the first module, the second module and the third module to the blender. The system also includes a pump that directs the output of the blender to a desired down hole location. The pump may be powered by natural gas or electricity. | 03-17-2011 |
| 20130269928 | DOWNHOLE TOOL FOR USE IN A DRILL STRING - A downhole tool in a drill string for mitigating hazards of a blockage in an annulus of the drill string. The downhole tool can sense blockages and selectively recirculate flow from within the annulus back to surface. Further, the downhole tool is made up of segments that are selectively detachable from one another, so that the segments above the point of detachment are removable from a wellbore. The bypass assembly includes a sleeve in the downhole tool with openings in its side; when the annulus reaches a set pressure, the sleeve slides to a position so the openings register with ports formed through a side of the tool to allow bypass flow. A processor in the downhole tool senses movement of the string, and when the string is axially stationary more than a designated period of time, the processor emits signals to detach the segments. | 10-17-2013 |
