  • Patent number: 10724356
    Abstract: A downhole separator performs the function of removing gas from liquids before the liquids enter the well pump. The formation fluid enters into a first, lower, chamber, of the separator and exits through channels to helical passageways on the exterior of the separator body. A shroud surrounds the separator body to serve as an outer wall of the helical passageways. Spiraling movement of the fluid forces the heavier liquids outward and causes separation of the lighter gas. The liquids and gas are ejected from the top of the separator body. The separated liquids drain downward by gravity pull to a liquid reservoir. Liquids in the reservoir are driven upward and flow through channels on the exterior of the separator body into a second, upper chamber, in the separator body which is coupled by tubing to the inlet of the pump.

  • Patent number: 10422899
    Abstract: A deterministic method for selecting a set of encoding weights for simultaneous encoded-source inversion of seismic data that will cause the iterative inversion to converge faster than randomly chosen weights. The encoded individual source gathers are summed (83), forming a composite gather, and simulated in a single simulation operation. The invention creates multiple realizations of the simulation (84), each with its own encoding vector (82) whose components are the weights for the shots in the composite gather. The encoding vectors of the invention are required to be orthogonal (82), which condition cannot be satisfied by random weights, and in various embodiments of the invention are related to eigenvectors of a Laplacian matrix, sine or cosine functions, or Chebyshev nodes as given by the roots of Chebyshev polynomials. For non-fixed receiver geometry, an encoded mask (61) may be used to approximately account for non-listening receivers.

  • Patent number: 10336544
    Abstract: A water storage and management system takes water from a water source, such as captured run-off, and through a piping system, directs a flow of the water into an aquifer for storage and future utilization. Using moisture detectors, the system ascertains the water content of different layers or zones of the aquifer and reports this information to a digital processor. The digital processor may utilize this information to issue instructions to one or more control valves to direct the flow of the water into portions of the aquifer which have additional storage capacity. The digital processor may also instruct a submersible pump to withdraw from the aquifer as desired.

  • Patent number: 10330348
    Abstract: Techniques are provided for extracting geothermal energy, by providing salt into a well shaft that ends in a chamber in the Earth surrounded by a source of geothermal energy. The salt melts and heats up to the temperature within the chamber. The hot molten salt is then extracted and the heat from the molten salt is used as a source of energy to generate electricity or drive an industrial process. The salt can be re-used once the heat is extracted in a closed-loop system. According to some techniques, the salt is conveyed down the well by a pneumatic conveyer system or in other cases by using a mechanical system, such as a screw drive. Once returned to the surface, the molten salt can be used to heat graphite blocks for energy storage or be stored and transported to remote locations to extract the heat energy.

  • Patent number: 10030484
    Abstract: An apparatus and a method of formulating an empirical correlation model that estimates inflow performance relationship (IPR) of a snaky well. The model provisions for determining inclination and azimuth direction of the snaky well. A plurality of grid models is simulated for a predetermined well bottom-hole pressure. The grid models are validated by comparing the response of each grid to the response of a horizontal well. Sensitivity analysis is performed to determine the impact of the snaky well parameters on the IPR of the snaky well. Additionally, regression analysis is performed based on the sensitivity analysis in order to determine Vogel based quadratic coefficient that estimates the IPR of the snaky well. A transformation of the snaky well parameters is performed in order to determine a sum of squared errors, whereafter a linear weighting of the transformed parameters is computed to determine a correlation parameter of the empirical model.

  • Patent number: 9971051
    Abstract: Methods and systems for separating multiple events from primary events in noisy seismic data are described. Multiples are predicted and then the predictions are improved by least-square matching filtering in the space and time domain. An adaptive curvelet domain separation (ACDS) is then performed and the ACDS equation is solved with an iterative soft-thresholding technique. Further processing can be added to compensate for prediction inaccuracy or variable/excessive seismic data noise by dividing the seismic data into predetermined bands and processing each band independently.
