  • Patent number: 10392915
    Abstract: A method of producing subterranean fractures in geologic formations for the extraction of hydrocarbons includes flowing an air and fuel mixture into a well hole. The well hole may then be sealed with a packer plug creating a compression chamber with the air and fuel mixture. A liquid, such as water, may be pumped into the well hole to create pressure in the compression chamber. The build-up of pressure eventually causes auto-ignition of the air and fuel mixture which fractures the formation. The water may then rush into the compression chamber which thermally shocks the area causing additional fractures. The water may vaporize to steam and thoroughly disinfect the well hole eliminating the need for added biocides.

  • Patent number: 10392922
    Abstract: A measure of inter-reservoir cross flow rate between adjacent reservoir layers which are productive of hydrocarbons is determined. With passage of time, pressure differentials between reservoir layers can grow due to continuous production from an active layer. In addition, the flow area between an active layer and adjacent layers can grow with time for a given reservoir system. These changing pressure and flow conditions with time can contribute to substantial amounts of cross flow rates, which need to be accounted for when characterizing the commercial producibility of the active layer. The inter-reservoir cross flow rate is based on a measure of specific permeability and of cross flow rate within a reservoir layer which is obtained from pressure transient tests of the reservoir formations.

  • Patent number: 10392929
    Abstract: Ground penetrating radar (GPR) measurements from a downhole well tool in a wellbore are obtained to identify length of fractures adjacent the wellbore. A ground penetrating radar transmitter of the downhole tool emits an electromagnetic pulse. The electromagnetic wave of the ground penetrating radar is diffracted on encountering an end or tip of a fracture, which acts as a secondary source. The diffracted signal is then collected by downhole receiver(s) of the downhole tool. Length of the fracture is determined based on the time of travel of the electromagnetic wave from its emission until its collection as a diffracted signal by the downhole receiver(s).

  • Patent number: 10392931
    Abstract: An asynchronous top-mounted pulser system for a measurement while drilling tool uses hydraulic flow, an obstruction, a piston-balance system, and an orifice, to create pressure pulses in drilling fluid, using hydraulic pressure on an obstruction in a main pulser to assist in closing the obstruction. A valve poppet is set above (upstream of) the orifice and is pushed by fluid flow towards a closing position. The piston-balance system, connected to the poppet and located downstream of the orifice in the main pulser, responds to net pressures on the upstream and downstream sides of the piston to move the poppet. The piston also responds to a spring assembly urging the piston downstream, and tending to move the valve poppet to a closed position. A servo pulser, located downstream of the main pulser, opens and closes a rotary shear servo valve-controlled bypass flow path to control the net pressures on the piston.

An electrical potential is then applied across the consumable aluminum anode and the workpiece to deposit an aluminum-containing layer onto the non-planar workpiece surface.
