摘要： A method and system that include receiving sensor data that is indicative of an operational status of a well construction equipment that is being utilized to construct a planned well that include receiving a well construction plan that includes information that is indicative of the planned well and the well construction equipment. The method and system additionally include accessing a database of operational sequences that are executable to be performed by the well construction equipment to construct a plurality of wells and selecting from the database an operational sequence to construct the planned well. The method and system further include electronically controlling the well construction equipment to autonomously perform the plurality of physical or mechanical operations of the selected operational sequence to drill at least one of: a selected portion of the planned well and a path along the selected portion of the planned well through a subterranean formation.

摘要： A supervisory control system for a well construction rig operable to perform well construction operations to construct a planned well at a wellsite. The supervisory control system may be installable in association with the well construction rig. The supervisory control system may comprise a supervisory controller communicatively connectable with a central controller of a rig control system of the well construction rig. The rig control system may be communicatively connected with and operable to control well construction equipment of the well construction rig. The supervisory controller may be operable to control the well construction equipment via the rig control system to cause the well construction equipment to perform the well construction operations. The central controller may be operable as an I/O interface for matching inputs and outputs of the supervisory controller with corresponding inputs and outputs of at least one piece of the well construction equipment.

摘要： Apparatus and methods for managing power at a wellsite. An example apparatus may include a well construction equipment operable to construct a well at the wellsite, a power supply system operable to output electrical power to the well construction equipment to facilitate operation of the well construction equipment, and a control system for controlling the well construction system. The control system may be operable to store a digital drilling program and cause the well construction equipment to perform planned well construction operations based on the digital drilling program. The digital drilling program may include an equipment operational plan indicative of the planned well construction operations to be performed by the well construction equipment to construct the well, and an electrical power plan indicative of a planned electrical power demand of the well construction equipment to perform the planned well construction operations.

摘要： Systems and methods for drilling a wellbore. The method includes measuring a first distance that a drilling device is raised while connected to a drill string, determining a weight-on-bit in the drill string, determining a second distance to lower the drilling device such that a drill bit at a lower extremity of the drill string approaches toward a bottom of the wellbore, based on the first distance and the weight-on-bit, and lowering the drilling device by the second distance.

摘要： A method for steering a downhole tool in a wellbore includes measuring a tool face when the drill bit is off-bottom, measuring an angular position of a drill string when the drill bit is off-bottom, and measuring a torque on the drill string when the drill bit is off-bottom. Measuring the tool face when the drill bit is on-bottom and measuring the torque on the drill string when the drill bit is on-bottom. Determining a transfer function comprising the angular position of the quill, the difference between the tool face when the drill bit is on-bottom and off-bottom, and the difference between the torque when the drill bit is on-bottom and off-bottom. The angular position of the drill string is varied at the surface, based upon the transfer function, to reduce an angle between the tool face when the drill bit is on-bottom and a target tool face.

摘要： A method of estimating extended reach for a downhole line traversing a deviated section of a well. The method may include storing line and well architectural and physical data and then performing a static analysis of substantially axial-exclusive estimated friction between the line and well wall during conveyance (which may be thought of as the contact force due to interference therebetween). A one dimensional dynamic analysis may then be performed. Thus, based on these factors, speed of the conveyance, vibration parameters of an incorporated vibration tool, etc., an efficient simulation of the conveyance may be run.
