20130062073 | Packer Assembly with a Standoff - An apparatus including a downhole tool for conveyance in a wellbore extending into a subterranean formation. The downhole tool includes a mandrel, and a first packer and a second packer expandable from the mandrel into contact with a wall of the wellbore. The downhole tool includes a standoff coupled to the mandrel between the first packer and the second packer and having a rigid outer perimeter that is diametrically larger than an outer perimeter of the mandrel. | 03-14-2013 |
20130118751 | FORMATION FRACTURING - A method described herein involves lowering a tool into a wellbore adjacent a subterranean formation; inflating a first packer on the tool to initiate a fracture of the formation; inflating second and third packers on the tool to seal an interval of the wellbore containing the fracture, the first packer being between the second and third packers; and pumping fluid into the interval to increase a pressure in the interval to propagate the fracture. | 05-16-2013 |
20140069640 | MINIMIZATION OF CONTAMINANTS IN A SAMPLE CHAMBER - A formation testing apparatus and method for obtaining samples with lower levels of contaminants is provided. Such a method can remove contaminants from at fluid sample, and can include the steps of obtaining fluid, from a formation and passing a first quantity of the fluid through a sample flow line. A connection between the sample flow line and a sample chamber can he opened, and a first portion of the first quantity of the fluid can be drawn into the sample chamber via a floating piston. The first portion can be forced out of the sample chamber, and this process can be repeated until sufficient contaminants have been removed. Finally, a second portion of the first quantity of the fluid can be drawn into the sample chamber as the fluid sample. | 03-13-2014 |
20140157883 | DUAL FLOWLINE TESTING TOOL WITH PRESSURE SELF-EQUALIZER - Flowline pressure equalizer systems, methods and/or apparatuses for use on a downhole tool are provided. A pressure equalizer may be provided in communication with two flowlines. The pressure equalizer may use equalizing chambers and equalizing pistons to regulate pressure in one or both flowlines. Further, one or more flow routing modules may be interchangeable to further alter the flow scheme between the flowlines. Different plugs may house various flow routing configurations such that the plugs may be installed and/or removed in the tool string automatically or by a user. | 06-12-2014 |
20150129220 | PUMP ACTUATED JAR FOR DOWNHOLE SAMPLING TOOLS - An apparatus configured to impart a force on a downhole component, having a piston configured to expand from a movement of a drilling fluid in a downhole environment, a weight configured to move from a first position to a second position, wherein the weight contacts the piston and the piston is configured to move the weight from the first position to the second position when the piston expands from movement of the drilling fluid, a spring configured to contact a bearing surface and the weight, wherein movement of the weight toward the second position compresses the spring, a return spring configured to impart a force on the weight to return the weight to the first position from the second position and a trigger mechanism configured to actuate a return of the weight from the second position to the first position by the return spring. | 05-14-2015 |
20150135816 | Water Line Control For Sample Bottle Filling - An arrangement for sampling a fluid, having a sample bottle with an associated piston, wherein the piston separates the sample bottle into an inlet side and a water side, a fluid sample line connected to the sample bottle at the inlet side, the fluid sample line transporting a fluid, a solenoid connected to the sample bottle on the water side of the sample bottle and a check valve connected to the sample bottle on the water side of sample bottle, wherein fluid enters the sample bottle on the inlet side upon actuation of at least one of the solenoid and the check valve on the water side of the sample bottle. | 05-21-2015 |
20150176376 | Packer Tool Including Multiple Ports - A tool to be used within a wellbore including a wall, the wellbore extending through a formation including formation fluid, includes a first packer and a second packer. The first packer includes a packer port to enable formation fluid flow through the first packer, with the second packer spaced from the first packer. The first packer and the second packer are expandable to abut the wellbore wall to form an interval within the wellbore between the first packer and the second packer, in which the tool further includes an interval port in fluid communication with the interval. | 06-25-2015 |
20150361791 | System And Method For Controlled Pumping In A Downhole Sampling Tool - A downhole tool designed to be disposed in a borehole of a subterranean formation is provided. The downhole tool includes a probe used to interface with the subterranean formation in order to sample fluid from or to inject fluid into the subterranean formation. The downhole tool also includes a sample flowline fluidly coupled to the probe and used to direct fluid through the downhole tool. The downhole tool further includes at least two volume chambers. These volume chambers each include a first side fluidly coupled to the sample flowline, a second side fluidly coupled to the guard flowline, and a piston separating the first side from the second side. The downhole tool is able to control a flow of fluid from a high pressure environment to a low pressure environment via the at least two volume chambers, the sample flowline, and the guard flowline. | 12-17-2015 |
