Abstract: Systems and methods of the present disclosure provide systems and methods for performing downhole formation testing operations. Certain methods include deploying a downhole toolstring of a downhole formation testing system to a downhole location within a wellbore extending through a subterranean formation, wherein the downhole toolstring includes a single packer positioned near a lower end of the downhole toolstring; setting the single packer within the wellbore to isolate one or more zones of interest of the subterranean formation in a lower portion of the wellbore below the single packer from an upper portion of the wellbore above the single packer; and, after setting the single packer within the wellbore, using the downhole toolstring to perform downhole formation testing on one or more fluids received from the one or more zones of interest by the downhole toolstring.

Abstract: Methods, systems, and computer readable storage mediums for managing downhole operations are disclosed. To manage downhole operations, the temperatures of various components of tools used in downhole environments may be taken into account. To preserve the life of the components of the tools, cooling flows may be used to retain temperatures of the components within operating ranges. By retaining the temperatures of the components within the operating ranges, the components may be less likely to become damaged, become impaired, and/or operate in undesired manners.

Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to conveying, via coiled tubing, a downhole well tool into a wellbore extending through a hydrocarbon-bearing reservoir, and performing a plurality of downhole well operations (production operations, perforation operations, testing operations, clean out operations, and so forth) using the downhole well tool. In general, the plurality of downhole well operations may be performed using the downhole well tool while maintaining full well control and without removing the downhole well tool from the wellbore.

Abstract: Processes for injection of fluids into a wellbore via drill pipe. In some embodiments, the process can include positioning a downhole apparatus on a drill pipe. The process can also include placing the downhole apparatus at a desired station depth within a wellbore. The process can also include attaching a cable to the downhole apparatus from an up-hole environment. The process can also include setting at least one packer to seal a space between at least a portion of the downhole apparatus and an inner surface of the wellbore. The process can also include introducing a fluid to the downhole apparatus through the drill pipe and using a pump to inject at least a portion of the fluid into a geological stratum.

Abstract: Systems and methods presented herein include an assembly of tools that can be arranged in a wellbore in such a way that allows a combination of formation testing (e.g., with a modular formation dynamics testing tool, a wireline formation testing tool, and so forth) and drill stem testing (DST). The assembly of tools enables performance of both types of activities potentially in a single run in the hole, and facilitate full control of the reservoir and formation fluids or, in case of injection, of injected fluids inside the tubing or drill pipe. In addition, the assembly of tools allows for multiple set points to perform zonal evaluations with the formation testing tools, and facilitate performance of full scale flow tests with the DST string.

Abstract: This disclosure relates to a separating a fluid having multiple phases during formation testing. For example, certain embodiments of the present disclosure relate to receiving contaminated formation fluid on a first flow line and separating a contamination (e.g., mud filtrate) from the formation fluid by diverting the relatively heavier and/or denser fluid (e.g., the mud filtrate) downward through a second flow line and diverting the relatively lighter and/or less dense fluid upward through a third flow line. In some embodiments, the third flow line is generally oriented upwards at a height that may facilitate the separation of the heavier fluid from the relatively lighter fluid based on gravity and/or pumps.

Abstract: A method of formation fluid sampling that includes setting a dual packer tool in a wellbore. The dual packer tool is used to isolate an interval between an upper packer and a lower packer. The method also includes drawing fluid from the interval with a lower inlet, until an oil fraction increases over a base line reading, and drawing oil from by pumping at a low rate with an upper inlet.

Abstract: A pressure testing module separable from and configured to be coupled with a tool base that is to be coupled along a downhole tool string to be conveyed within a wellbore extending into a subterranean formation. The pressure testing module includes a chamber and a piston assembly slidably disposed within the chamber, thus dividing the chamber into a first chamber portion and a second chamber portion. The piston assembly is operable to move in response to hydraulic fluid being pumped into the first chamber portion and to draw formation fluid of the wellbore into the second chamber portion in response to the movement of the piston assembly.
