  • Patent number: 10876390
    Abstract: There is described a method of controlling a drilling operation. A pipe joint is determined to be entering a rotating control device (RCD). In response to determining that the pipe joint is entering the RCD, a weight-on-bit (WOB) setpoint is increased so as to increase a measured WOB. After increasing the WOB setpoint, the pipe joint is determined to be exiting the RCD. In response to determining that the pipe joint is exiting the RCD, the WOB setpoint is decreased so as to decrease the measured WOB.

  • Patent number: 10859730
    Abstract: Technologies related to training machine-learning-based surrogate models for phase equilibria calculations are disclosed. In one implementation, an equation of state (EOS) for each of one or more regions of a reservoir is determined based on results of one or more pressure, volume, or temperature (PVT) experiments conducted on samples of downhole fluids obtained from one or more regions of the reservoir. Compositions of the samples of the downhole fluids are determined and spatially mapped based on interpolations between the one or more regions of the reservoir. One or more PVT experiments are simulated for the spatially mapped compositions of the downhole fluids using the determined EOS to create a compositional database of the reservoir. One or more machine-learning algorithms are trained using the compositional database, and the trained one or more machine-learning algorithms are used to predict phase stability and perform flash calculations for compositional reservoir simulation.

  • Patent number: 10544637
    Abstract: A device for limiting the flow of drilling fluid through a section of drill string is described. The device includes a cylindrical tube with holes in its periphery. Flow enters the device through an upper end of the tube and a portion of the flow exits through the lower end of the tube. In addition, some of the flow is diverted through the peripheral holes. A valve piston is supported near the lower end of the tube by a spring of approximately constant force through its range of travel. The valve piston moves axially as the flow rate through the tube changes flow rate to ensure that a substantially constant amount of flow exits through the lower end, while the excess flow is diverted from the tube through the peripheral holes. A means of damping or stopping the axial movement of the valve piston is included in the device.

  • Patent number: 10533408
    Abstract: In drilling into a subterranean formation, several factors influence the rate of penetration, including, but not limited to, the type of formation being drilled, the weight on bit, and the rotational speed of the drill bit. Disclosed are a system and method for controlling the rotational speed of a drill bit based on regulation of fluid flow to the motor driving the bit, while maintaining at least a minimum flow of fluid to the annulus to clear debris from downhole during drilling. Regulation of fluid flow to the motor and to the annulus may be accomplished utilizing a flow diverter configured to adjust a flow ratio depending on drilling conditions in order to maximize efficiency of the motor downhole during drilling.

  • Patent number: 10428638
    Abstract: A system and method for drilling a borehole using a drilling rig having a rotary drill bit includes monitoring one or more drilling parameters; determining whether the one or more monitored drilling parameters are within predetermined specifications for one or more of the monitored drill parameters; and, executing an exception control procedure for control of a drilling parameter. The exception control procedure receives an input sensor value associated with a drilling parameter and applies feedback control to establish a scaled error value that is used to compute a setting value for the drilling parameter. The drilling parameters controlled may include the rotation speed of the drill bit, the feed rate of the drill bit, the weight-on-bit, or rotation torque during retraction of the drill bit. A computer-readable database of specifications of drill bits may be provided as a part of the system.

  • Patent number: 10408007
    Abstract: A downhole tool includes a valve assembly and a shock absorbing assembly. The valve assembly includes a valve spring operatively connected to a valve body. The shock absorbing assembly includes a spring operatively connected to a shock absorbing body having a fluid passage therethrough. The valve body is configured to selectively engage the shock absorbing body to create a fluid tight seal over the fluid passage in a first position, and to allow a fluid flow through the fluid passage in a second position. The repeated movement cycle of the selective engagement between the valve body and the shock absorbing body generates a pressure pulse or a varying pressure differential across the downhole tool. The repeated movement cycle is powered by a fluid flow. The tool may be selectively activated and deactivated.

  • Patent number: 10408042
    Abstract: The invention discloses a series of methods to design drilling trajectory and control drilling operations in a optimized way in carbonate formation. The trajectory design method comprises: utilizing earthquake data to obtain contours of the carbonate rock fractures; determining a safe distance from each carbonate rock fracture; determining a segmented drilling trajectory for each fracture or vuggy structures in carbonate formation; and sequentially connecting the segmented drilling trajectories of neighboring fracture and vuggy to obtain a smooth horizontal drilling trajectory. The invention optimizes the carbonate rock reservoir drilling trajectory, thus improving connection between a horizontal well and the fractures. This reduces development costs, increases exploration and development efficiency and, at the same time, eliminates leaks resulting from the drilling process, thereby allowing for smooth drilling to a target well depth.

  • Patent number: 10400530
    Abstract: The present disclosure relates to systems, assemblies, and methods for facilitating fluid flow during/after landing of logging tools in a bottom hole assembly. In operation, a memory logging tool is lowered through a longitudinal bore of a drill pipe string and landed in a bottom hole assembly disposed at the end of the drill pipe string. Drilling fluid is pumped behind the logging tool to assist with downward movement of the tool. As the logging tools land, partial fluid flow path is blocked by the logging tools. The fluid pressure can rise in response to the narrowing of the fluid flow path. Facilitating fluid flow through and/or around the logging tools can put the rising fluid pressure in a proper range for powering the logging tools to land and monitoring purposes.
