The mixture includes about 50% to about 99% by weight percent of the first metal, about 1% to about 50% by weight percent of a second metal, about 1% to about 50% by weight percent of a third metal. In one embodiment, the first metal comprises tungsten, the second metal may comprise nickel, and the third metal may comprise copper. | 03-19-2009 |
20100276136 | INTERNALLY SUPPORTED PERFORATING GUN BODY FOR HIGH PRESSURE OPERATIONS - A perforating system having a perforating gun with a high pressure gun body. The gun body can be thickened so that no empty space is present between it and a corresponding gun tube. Alternatively, the gun body could be a solid cylinder with slots radially formed therein to receive a shaped charge. In another embodiment, a flowable material, such as foam, fluid, sand, ceramic beads, eutectic metal, and combinations thereof, is provided in the space between the gun body and gun tube. | 11-04-2010 |
20100276144 | HIGH PRESSURE/DEEP WATER PERFORATING SYSTEM - A perforating system having a perforating gun with a gun body formed from a ductile material. The gun body deforms under pressure while maintaining sufficient structural integrity to remain intact, and without rupturing or leaking. A flowable material can be inserted within the gun body that provides additional support to the gun body. | 11-04-2010 |
20120168162 | Non frangible perforating gun system - A shaped charge assembly for use in a perforating gun that further comprises a charge carrier, and gun housing. The charge carrier substantially encapsulates the closed portion of the shaped charge and extends from the outer periphery of the shaped charge to the inner diameter of the associated gun housing. Encapsulating the shaped charge substantially reduces the introduction of debris into the wellbore resulting from detonation of the perforating gun shaped charges. The charge carrier can include a multiplicity of shaped charges therein. | 07-05-2012 |
20130019671 | OPTIMIZATION OF SAMPLE CLEANUP DURING FORMATION TESTING - Disclosed is a formation testing tool for extracting formation fluid from an earth formation penetrated by a borehole having a drilling fluid. The tool includes: a sample flow element configured to extract formation fluid from the formation in a sample zone; a sample zone seal forming a perimeter defining the sample zone; a contamination removal flow element configured to extract formation fluid contaminated with the drilling fluid from a contamination removal zone in the formation; a contamination removal zone seal forming a perimeter defining the contamination removal zone, which surrounds and excludes the sample zone; and a controller configured to control a sample flow rate in the sample flow element and a contamination removal flow rate in the contamination flow removal element in order to decrease an amount of time required to acquire a sample of the formation fluid having an acceptable amount of contamination. | 01-24-2013 |
20130292174 | COMPOSITE LINERS FOR PERFORATORS - A shaped charge having a charge case and liner with an outer layer and an inner layer. The liner is a generally hollow frustoconically shaped member with an open end and a closed end, where the closed end of the liner inserts into an opening in the charge case. An explosive is provided between the liner and the charge case. The inner layer of the liner includes a higher density material than material used for forming the outer layer. | 11-07-2013 |
20140054030 | SPEED CONTROL DEVICES AND METHODS FOR DROP DOWN TOOLS - An apparatus for evaluating an earth formation intersected by a wellbore may include a logging tool conveyed into the wellbore through a drilling tubular, a speed control device associated with the logging tool, and a sensor operatively associated with the logging tool. In use, the speed control device varies an annular flow space between the speed control device and a surface adjacent to control speed. The flow space may be varied using a annular member that flexes between a nominal diameter and a second larger diameter. | 02-27-2014 |

20120097452 | Downhole Tool Deployment Measurement Method and Apparatus - In one aspect, an apparatus for conveying a tool while drilling a wellbore is provided. The apparatus includes a line coupled to the tool, a conveying assembly coupled to the line, the conveying assembly located at a surface and configured to release the line to convey the tool into the drill string and a sub including a passage for the line to pass therethrough. The apparatus also includes a measuring device configured to determine a position of the tool within the drill string by determining a length of the line that is conveyed along with the tool into the drill string. | 04-26-2012 |
20140054030 | SPEED CONTROL DEVICES AND METHODS FOR DROP DOWN TOOLS - An apparatus for evaluating an earth formation intersected by a wellbore may include a logging tool conveyed into the wellbore through a drilling tubular, a speed control device associated with the logging tool, and a sensor operatively associated with the logging tool. In use, the speed control device varies an annular flow space between the speed control device and a surface adjacent to control speed. The flow space may be varied using a annular member that flexes between a nominal diameter and a second larger diameter. | 02-27-2014 |
20140123046 | SELECTION OF BOREHOLE AND WELL DATA FOR VISUALIZATION - A visualization system for providing a preview of data obtained in a borehole and available for selection includes a processor configured to process the data based on user input and instructions and provide output for display on a display device; a computer-readable medium configured to store the instructions, the instructions including commands to output values of two or more types of parameters at two or more depth values for display; and a user interface configured to facilitate selection of one or more of the two or more types of parameters for further visualization and processing. | 05-01-2014 |
20140152659 | GEOSCIENCE DATA VISUALIZATION AND IMMERSION EXPERIENCE - A method for presenting measurements of properties of a subsurface material to a user includes: conveying a carrier through a borehole penetrating the subsurface material; performing a plurality of measurements of multiple properties of the subsurface material at multiple depths in the borehole using a plurality of downhole tools disposed at the carrier; constructing, with a processor, a three-dimensional mathematical model of the subsurface material using the plurality of measurements, the model having data from the plurality of measurements of the multiple properties; receiving, with the processor, an input from a user directing the processor to generate a three-dimensional image of the subsurface material as seen from a virtual viewer-window viewing the model, the input having a three-dimensional position and three-dimensional viewing direction of the virtual-viewer window within the model; generating the three-dimensional image with the processor; and displaying the generated three-dimensional image on a display. | 06-05-2014 |
