  • Patent number: 9759064
    Abstract: A method of testing an earth formation can include incrementally opening a choke while drilling into the formation is ceased, thereby reducing pressure in a wellbore, and detecting an influx into the wellbore due to the reducing pressure in the wellbore. Another method of testing an earth formation can include drilling into the formation, with an annulus between a drill string and a wellbore being pressure isolated from atmosphere, then incrementally opening a choke while drilling is ceased, thereby reducing pressure in the wellbore, detecting an influx into the wellbore due to the reducing pressure in the wellbore, and determining approximate formation pore pressure as pressure in the wellbore when the influx is detected. Drilling fluid may or may not flow through the drill string when the influx is detected. A downhole pressure sensor can be used to verify pressure in the wellbore.

The adjustable drill string housings permit adjustment of a bend angle in the housings without removing the housings from a wellbore. In some exemplary embodiments, the bend angle can be adjusted by changing the internal stresses in a support member carried by the housings. In other embodiments, the bend angle may be adjusted by causing failure of sacrificial support members carried by the housings, and the failure may be caused by delivering chemicals through a chemical delivery system to the sacrificial support members. Methods of operating the adjustable drill string housings include multi-lateral drilling operations wherein the bend angle is adjusted when a casing window has been detected.

  • Patent number: 9416597
    Abstract: Bearing assemblies for downhole tools include a compensator member operatively associated with a slidable member and a bearing member. The slidable member is movable longitudinally relative to the bearing member. Such movement of slidable member occurs when a force acts upwardly on the downhole tool. Thus, the slidable member facilitates absorption of the upward force acting on the downhole tool. During movement of the slidable member, the compensator member is moved from its expanded position to one of its plurality of compressed positions. As a result, the compensator member becomes biased or further biased toward the expanded position. After the upward force dissipates, the compensator member releases some of its stored energy to move from a compressed position toward the expanded position. Longitudinal movement of the slidable member facilitates maintaining engagement of the downhole tool in its working position so that interruptions of operations are minimized.

  • Patent number: 9222310
    Abstract: Apparatus for clearing particles from a lateral drilling operation in strata beside a well. The drilling apparatus is part of a down hole unit and is configured for extending from a lateral opening of the unit into a lateral passage in the adjacent strata, and the operation of the drilling apparatus discharges particles from the lateral passage toward the lateral opening. The invention deflects or redirects the particles discharged from the lateral passage, away from the lateral opening, to prevent clogging or blocking of an internal passage or elbow through the down hole unit, using a pressurized fluid such as a gas or an emulsion. The pressurized fluid can also be configured for carrying the particles upwardly through the well to the surface, and for reducing or removing a hydrostatic head in the well.

  • Patent number: 9157309
    Abstract: A system and method for surface steerable drilling are provided. In one example, the system receives feedback information from a drilling rig and calculates an estimated position of a drill bit in a formation based on the feedback information. The system compares the estimated position to a desired position along a planned path of a borehole. The system calculates multiple solutions if the comparison indicates that the estimated position is outside a defined margin of error relative to the desired position. Each solution defines a path from the estimated position to the planned path. The system calculates a cost of each solution and selects one of the solutions based at least partly on the cost. The system produces control information representing the selected solution and outputs the control information for the drilling rig.

  • Patent number: 9134457
    Abstract: Methods for upscaling digital rock modeling data are described. Core-plug samples for pore-scale modeling are chosen using whole-core mini-permeability grids and conventional CT scans. Pore models or pore-network models are used for flow modeling. Borehole-scale models use MPS (Multi-Point Statistics) to combine mini-permeability grids and conventional CTscans of whole core with electrical borehole images to create 3D numerical pseudocores for each RRT (Reservoir Rock Type). Effective SCAL properties computed from various MPS borehole-scale realizations or models are used to populate interwell-scale models for each RRT. Effective properties computed from flow simulations for interwell volumes are used to populate full-field scale models. At the full-field scale, outcrop analogs, sequence stratigraphy, forward stratigraphic models, diagenetic models, and basin-scale models are combined using MPS to improve flow simulations.

  • Patent number: 9121224
    Abstract: A vibrational tool with tool axis rotational mass and method is disclosed, which may be utilized to assist in lowering a drill string into a wellbore. A reciprocating member and rotatable mass are mounted within a vibrational tool housing. A plurality of curved passageways are positioned to induce rotation in response to fluid flow through the tool housing. As the rotatable mass rotates, a mechanical interconnection causes the reciprocating member to reciprocate, and results in vibrational forces for moving a bottom hole assembly.

  • Patent number: 9110188
    Abstract: Systems, methods, and software for detecting bed boundary locations are described. In some aspects, the boundaries of a subsurface layer are identified based on a measurement from a logging point and a gradient associated with the measurement from the logging point. A first measurement is generated based on operating a transmitter and a receiver of a resistivity logging tool at a first tool depth. The gradient is calculated from the first measurement and a second measurement. The second measurement is generated based on operating the transmitter and the receiver of the resistivity logging tool at a second, different tool depth.
