Patent number: 10151855Abstract: A subsurface hydrocarbon reservoir with wells is simulated by sequential solution of reservoir and well equations to simulate fluid flow inside the reservoir and well production rates. Sequential solution of reservoir and well equations treats wells as specified bottom hole pressure wells. This avoids solving large matrices resulting from the simultaneous solution of the reservoir and well equations which can be computationally very expensive for large number of unknowns and require special sparse matrix solvers. Such sequential solution involves regular reservoir system solvers complemented by a small matrix for the numerical solution of the well bottom hole pressures. The solution is performed on a matrix of the transmissibilities of the adjacent reservoir cells to the well cells at the perforated well intervals; and a vector of unknown reservoir potentials for the adjacent reservoir cells.Type: GrantFiled: March 4, 2016Date of Patent: December 11, 2018Assignee: Saudi Arabian Oil CompanyInventor: Ali H.

Patent number: 10151895Abstract: An insulated utility vehicle for supporting a utility worker during the performance of a task is provided. The utility vehicle comprises a base, a boom assembly, and a utility platform. The base includes a power source of electrical energy and an energy emission assembly for emitting light energy within an enclosed housing. The boom assembly presents a proximal end pivotably attached to the base. An insulated energy transmission assembly associated with the boom assembly for receives and transmits the emitted light energy from the energy emission assembly. The utility platform is secured to a distal end of the boom assembly. An energy reception assembly associated with the utility platform receives the transmitted light energy from the energy transmission assembly and converts at least a portion of the transmitted light energy into electrical energy, which can be utilized by the utility worker in the utility platform to power a device.Type: GrantFiled: August 12, 2015Date of Patent: December 11, 2018Assignee: Altec Industries, Inc.Inventors: David K. Boger, Abdellatif Elhomani

Patent number: 10151899Abstract: A flat drop cable has notches or other structures for enhancing the stripability of the jacket from the a core of the flat drop cable. The notches can have an angled configuration with surfaces that converge as the notch extends into the jacket. Inner edges of the notches can be positioned along a tear path that intersects the core of the flat drop cable. For example, the notches can be offset from a minor axis of the flat drop cable a sufficient distance such that the notches are positioned outside a central boundary region that extends tangent to sides of the core and parallel to the minor axis of the flat drop cable.Type: GrantFiled: January 22, 2014Date of Patent: December 11, 2018Assignees: COMMSCOPE TECHNOLOGIES LLC, COMMSCOPE TELECOMMUNICATIONS (SHANGHAI) CO.
