  • Patent number: 10584583
    Abstract: A method including positioning a downhole acquisition tool in a wellbore in a geological formation; performing a pretest sequence to gather at least one of pressure or mobility information based on downhole acquisition from a sample line, a guard line, or both while the downhole acquisition tool is within the wellbore. The pretest sequence includes controlling a valve assembly to a first valve configuration that may allow the fluid to flow into the downhole tool via one or more flowlines toward a pretest system. The one or more flowlines include the sample line only, the guard line only, or both the sample line and the guard line; and drawing in the fluid through the one or more flowlines. The method also includes controlling the valve assembly to a second valve configuration. The second valve configuration is different from the first valve configuration and may block the one or more flowlines from drawing in the fluid.

  • Patent number: 10533693
    Abstract: Apparatus and methods for filling a pressure compensated fluid container with a liquid. An example method includes restraining movement of a piston slidably disposed within the fluid container in a first piston position, wherein the piston divides the fluid container into first and second portions. The method further includes pumping the liquid into the first portion to compress gas located within the first portion, stopping the pumping of the liquid into the first portion, and stopping the restraining of movement of the piston to permit the piston to move to a second piston position due to expansion of the gas compressed within the first portion.

  • Patent number: 10192011
    Abstract: A method for estimating wave field characteristics in 3D comprising the following steps: using a ray trace model to estimate RF wave front paths as they propagate from a transmitter to a plurality of given points within a geographical area of interest; constructing a ray bundle for each point; sorting the points into mode constellations according to the points' hop count and apogee characteristics; constructing a Delaunay triangulation of each mode constellation; computing a covariance estimation for each triangle in each mode constellation; and estimating the wave field characteristics over the entire geographical area of interest based on a summation of constituent ray bundles' characteristics within each mode constellation.
