摘要： An orientation sensing apparatus includes a rotatable first member, an orientation sensor device fixed with the first member for generating orientation data relating to an orientation sensor device orientation, and a rotation sensor device for generating rotation data relating to rotation of the first member. A method for determining an orientation includes assembling a set of sensor data including the orientation data and rotation data and processing the set of sensor data to generate a set of corrected orientation data. The set of corrected orientation data includes the orientation data which has been corrected using the rotation data to reduce the effects of rotation of the first member and misalignment of the gravity sensor device. One or more sets of corrected orientation data may be processed to determine an inclination orientation of the first member or a toolface orientation of a second member which is connected with the first member.

摘要： A method includes directionally drilling, with a pulse power drill string, of a borehole into a subsurface formation using pulse power. The directionally drilling comprises generating, by an electrical source, an electrical energy and storing, by a primary capacitor, the electrical energy. The method includes periodically discharging the electrical energy from the primary capacitor to be received by a switching device having a number of outputs, wherein each output of the number of outputs is electrically coupled to an electrode of a number of electrodes positioned on an electrode assembly; and unevenly distributing, by the switching device, the electrical energy across the number of electrodes based on selecting a subset of the number of electrodes to receive the electrical energy to alter a direction of the drilling of the borehole based on emitting of the electrical energy by the selected subset of the number of electrodes into the subsurface formation.

摘要： The present disclosure relates to systems and methods of determining a wellbore position in a subterranean formation by using gravity sensors to detect a gravity anomaly related to a presence of the wellbore, contents within the wellbore, and or fluid flowing through an interface of the wellbore. A model of the subterranean formation predicts a gravity profile, including the gravity anomaly, and the model may be constrained with a depth of the gravity anomaly as calculated with at least one of a known dimension or a known gravitational field change related to the gravity anomaly. The wellbore position is determined within the model by changing model input data until the gravity profile converges with the gravity anomaly.

摘要： A first characteristic of a first discharge of electrodes of a pulse power drilling assembly in a borehole of a subterranean formation is determined. The first characteristic is based on a measurement of the first discharge. A second characteristic of a second discharge of the electrodes is determined. The second discharge occurs after the first discharge, and the second characteristic is based on a measurement of the second discharge. A difference between the first characteristic and the second characteristic is determined. A boundary layer of the subterranean formation is determined based on the difference.
