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 includes placing a downhole acquisition tool in a wellbore in a geological formation within a hydrocarbon reservoir. The wellbore or the geological formation, or both, contain a reservoir fluid. The method also includes performing downhole fluid analysis using the downhole acquisition tool in the wellbore to determine at least one measurement associated with the reservoir fluid and using a processor to: estimate at least one fluid component property by using an equation of state based at least in part on at least one measurement associated with the reservoir fluid and simulate a diffusion process using a diffusive model that takes into account the at least one estimated fluid property. The diffusive model accounts for gravitational diffusion of at least one or more components in the reservoir fluid. The method also includes using the processor to estimate one or more reservoir fluid geodynamic processes based at least in part on the at least one fluid property; compare the estimated one or more reservoir fluid geodynamic processes with the at least one measurement associated with the reservoir fluid; and output one or more reservoir fluid geodynamic processes corresponding to the at least one measurement associated with the reservoir fluid.

Abstract: Techniques for improving implementation of a downhole tool string to be deployed in a borehole formed in a sub-surface formation. In some embodiments, a design device determines a model that describes expected relationship between properties of the downhole tool string, the borehole, the sub-surface formation, and mud cake expected to be formed in the borehole; determines calibration locations along the borehole based on properties of the borehole; determines candidate spacer configurations based on contact force expected to occur at contact points between the downhole tool string and the mud cake when deployed with each of the candidate spacer configuration via the model; and determines a final spacer configuration to be used to attach one or more spacers along the downhole tool string based on expected head tension to move the downhole tool string when deployed in the borehole with each of the candidate spacer configurations via the model.

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: 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.
