Abstract: Processes and systems for microseismic event detection. In some embodiments, the process can include acquiring seismic data with a dense seismic receiver array; converting seismic data into an image domain dataset; detecting one or more seismic waveform edges; characterizing within the image domain dataset one or more linear segments which each define a portion of one or more of the one or more seismic waveform edges, and wherein the linear segments are functions of one or more seismic arrival times and one or more subterranean depths; and estimating the subterranean depth of the one or more microseismic events within a subterranean formation based on the one or more linear segments.

Abstract: A system and method for improving the 3D positional description of well geometry, subsurface measurements and subsurface services along the wellbore and 3D positional uncertainty. The method selects a well reference point, calibrates the AHD, Incl and Az measurements, selects a measurement station positioned, observes measurements at the measurement station, selects at least one or more additional measurement station(s), repeats the measurements, transforms calibrated interval AHD, Incl. and Az observed measurement values into V, N and E interval values, summates V, N and E interval values to create a 3D positional description of each measurement station. The method then determines the AHD, Incl. and Az value uncertainties at each measurement station, calculates and concatenates the AHD, Incl. and Az value uncertainties and creates a depiction of these associated uncertainties along the length of the wellbore in terms of V, N and E positions from ZDP.

Abstract: 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.

Abstract: A method for performing wellbore correlation across multiple wellbores includes predicting a depth alignment across the wellbores based on a geological feature of the wellbores. Predicting a depth alignment includes selecting a reference wellbore, defining a control point in a reference signal of a reference well log for the reference wellbore, and generating an input tile from the reference signal, the control points, and a number of non-reference well logs corresponding to non-reference wellbores. The well logs include changes in a geological feature over a depth of a wellbore. The input tile is input into a machine-learning model to output a corresponding control point for each non-reference well log. The corresponding control point corresponds to the control point of the reference log. Based on the corresponding control points output from the machine-learning model, the non-reference well logs are aligned with the reference well log to correlate the multiple wellbores.

Abstract: Devices, systems and methods for cutting openings in a wellbore tubular by a slot cutting assembly having an anchoring system and a slot cutting tool. The anchoring assembly anchors the slot cutting assembly within the wellbore. The slot cutting tool has an extendable cutting blade that is pushed into the wellbore tubular to cut an opening through the tubular. The slot cutting tool may have an extendable stabilizing arm to stabilize and assist with cutting by the blade. The slot cutting assembly may have azimuth and depth sensors to assist with positioning the tool at a desired position downhole. A surface system may be used to control the position of the slot cutting assembly downhole.

Abstract: A system, method, and apparatus can identify groundwater as a drilling machine (200) drills a drill hole (100). Presence or not of groundwater can be continuously monitored as the drilling machine (200) drills the drill hole (100) using one or more groundwater or moisture sensors (240) to detect moisture or water content of cuttings from the drill hole (100). Such data from the sensor(s) (240) can be processed to determine the presence or not of groundwater and associate the determination with the corresponding location within the drill hole (100). A mapping or logging of the drill hole (100) can be generated with the location or locations where the presence of groundwater is identified.

Abstract: A method of determining the depth of a sidewall core sample taken from a borehole relative to a reference log of the borehole. The method includes obtaining a reference log recorded on a reference log depth scale and a borehole image log recorded on a borehole image log depth scale of a portion of the borehole from which the sidewall core sample has been taken. The method further includes generating a calibrated borehole image log from the borehole image log and the reference log and identifying a candidate sidewall core image artifact in the calibrated borehole image log. The method also includes assigning a confidence value for the candidate sidewall core image artifact based on a characteristic of the candidate sidewall core image artifact, and determining, using the confidence value, a probability that the sidewall core sample was collected at a certain depth on the reference log depth scale.

Abstract: The present invention relates to a system and method to determine water level in borewell (102). The system and method involve a non-mechanized impact generator or a sound pulse generator (108) adapted to be hit at a top end of borewell (102) to generate a first acoustic signal that travels through a housing of the borewell (102). An acoustic sensor couple with an amplifier (112) positioned at the top of borewell detects the first acoustic signal, and a second acoustic signal associated with the reflection of at least a part of the first acoustic signal with a body of the water within the borewell (102). The system (100) includes a mobile device (110) to transmit data pertaining to position of the sensor (112), and impact generator or a sound pulse generator (108), and time stamp pertaining to detection of the first and second acoustic signals, to a computing unit (108) that processes the data to determine level of the water in the borewell (102).
