20090250221 | Method of supplying a powdered chemical composition to a wellsite - A method of conditioning a compacted polymeric powder to a flowable and meterable state. The polymeric powder is compacted during transport such that the flowability is hindered. To increase flowability, gas is introduced into the polymeric powder to condition the same to an improved flowable and meterable state. | 10-08-2009 |
20130293234 | System and Method for Measuring Downhole Parameters - Systems, tools and techniques for measuring downhole parameters are provided. The techniques involve providing a downhole tool with a sensing apparatus. The sensing apparatus has at least one source positionable about the downhole tool, at least one sensor electrode positionable about a front face of the downhole tool for measuring electrical signals from the source, and a raised insulating cover positionable along the front face of the downhole tool for defining at least one contact surface. The raised insulating cover extends over at least a portion of the sensor electrode whereby the sensor electrode is positionable adjacent to the subterranean formation for electrically coupling thereto without direct contact therewith. | 11-07-2013 |
20140014371 | EXPANDABLE DOWNHOLE SEAT ASSEMBLY - A technique includes deploying a seat assembly having a plurality of segments into a tubing string installed in a well and expanding the seat assembly at a downhole location in the well to secure the assembly to the tubing string and form a seat that is adapted to receive an untethered object. The technique includes receiving the untethered object in the seat of the seat assembly and using the received untethered object in the seat assembly to perform a downhole operation in the well. | 01-16-2014 |
20140202708 | DOWNHOLE COMPONENT HAVING DISSOLVABLE COMPONENTS - An apparatus that is usable with a well includes a first component and a second component. The first component is adapted to dissolve at a first rate, and the second component is adapted to contact the first component to perform a downhole operation and dissolve at a second rate that is different from the first rate. | 07-24-2014 |
20140216758 | DEPLOYING AN EXPANDABLE DOWNHOLE SEAT ASSEMBLY - A method includes running an assembly on a tool in a contracted state into a well. The assembly includes segments that are adapted to be radially contracted and arranged in a first number of layers along a longitudinal axis of the assembly in the contracted state of the assembly. The technique includes using the tool to expand the assembly downhole in the well to transition the assembly between the contracted state and an expanded state. Using the tool to expand the seat assembly includes radially expanding the segments and longitudinally contracting the segments to arrange the layers in a second number of layers having at least one layer less than the first number. | 08-07-2014 |
20140216759 | DEPLOYING AN EXPANDABLE DOWNHOLE SEAT ASSEMBLY - A technique that is usable with a well includes deploying a seat assembly into a tubing string; releasing the seat assembly at a downhole location inside the tubing string; pumping the seat assembly to a restriction in the tubing string at a second downhole location; and using an untethered object received in a seat assembly to form an obstruction in the tubing string. | 08-07-2014 |
20140284050 | Downhole Pressure Compensator and Method of Same - The techniques herein relate to a pressure compensation system for a sensor in a wellbore having a wellbore fluid therein. The system includes a downhole tool ( | 09-25-2014 |
20150075816 | SEGMENTED RING ASSEMBLY - A technique that is usable with a well includes deploying a segmented ring assembly in the well; and disposing the segmented ring assembly between a first element fixed in place in the well and a second unfixed element. The technique includes using the second element to compress the assembly to produce radially and tangentially acting forces on segments of the assembly. | 03-19-2015 |
