  • Patent number: 9540901
    Abstract: A well tool can include a swellable material, and a degradable material which supports the swellable material, but which degrades in response to contact with a selected fluid in a well. A packer for use in a subterranean well can include a swellable material, and a degradable material which supports the swellable material. A method of unsetting a packer in a subterranean well can include the steps of, after the packer has been set in the well, exposing a degradable material of the packer to a selected fluid, thereby degrading the degradable material, and a seal element of the packer being unsupported by the degradable material in response to the exposing step.

  • Patent number: 9528323
    Abstract: A fluid drilling head for drilling a bore hole through rock. The fluid drilling head has a rotatable nozzle assembly incorporating a plurality of nozzles arranged to form fluid jets when provided with a supply of drilling fluid under pressure. The fluid jets include pilot jets directed in the general direction of movement of the drilling head and reaming jets directed generally radially and arranged to enlarge the initial hole formed by the pilot jets. A gauging ring is located behind the cutting head and sized to the intended diameter of the bore hole. The gauging ring is arranged to slide axially relative to the rotating cutting head between a rearward position where the reaming jets are exposed, and a forward position where some or all of the reaming jets are shrouded by the gauging ring and inhibited from enlarging the diameter of the bore hole.

  • Patent number: 9528355
    Abstract: There is provided a system for producing oil from a well bore extending through a fossil fuel reservoir. The system includes a plurality of perforations defined in the casing proximate the fossil fuel reservoir. A gas flow tube is in communication with the annulus volume of the casing proximate the wellhead. A gas valve is coupled to the gas flow tube, with the gas valve configured to selectively open and close the gas flow tube. A controller, is coupled to the gas valve, with the controller configured to control the opening and closing of the gas valve. The opening and closing of the gas valve maximizes the volumetric rate of oil flow into the annulus volume through the perforations from the reservoir by displacing liquid in the annulus volume with a gas volume between the gas valve and the perforations.

  • Patent number: 9416637
    Abstract: A system and method enabling flow control with respect to a well related fluid. The system utilizes a choke manifold with a choke that can serve the function of both a fixed choke and an adjustable choke. The choke comprises components that are selectively adjusted to effectively provide differing calibrated flow paths along which the well related fluid flows when passing through the choke manifold. The choke manifold also may be combined with other system components in an efficient arrangement that facilitates handling of a variety of fluids, including multiphase fluids.
