摘要： Methods and systems for determining well productivity include acquiring measurement data from a plurality of in-situ sensors located within a hydraulically fractured subterranean formation; classifying the noise degree for sensors of the plurality based on the acquired measurement data; selecting sensors from the plurality by minimizing noise degree while maintaining coverage of the subterranean formation above a user defined threshold; extracting data from the selected sensors; and estimating fracture half-length and well productivity potential based on the extracted data.

摘要： An assembly includes two tubular elements, a primary and a secondary seal arranged between the two tubular elements, a seal cavity formed between the two tubular elements and the primary and the secondary seal, and a seal monitoring apparatus having a housing and a position sensor. The housing has a chamber enclosing a separator which divides the chamber into a first and a second sub-chamber. The first sub-chamber is fluidly connected to the seal cavity and is filled with a hydraulic fluid. The separator is movable in a first direction relative to the housing to increase a volume of the first sub-chamber and decrease a volume of the second sub-chamber, and in a second direction to decrease the volume of the first sub-chamber and increase the volume of the second sub-chamber. The position sensor generates an electrical signal which represents a position of the separator relative to the housing.

摘要： There are described methods, systems, and computer-readable media for detecting events in a conduit. Multiple lengths of optical fiber positioned alongside a conduit are used to detect a signal. For each length of optical fiber, interferometric data is obtained from the detected signal. The interferometric data obtained for one length of optical fiber is compared to the interferometric data obtained for one or more other lengths of optical fiber. Based on the comparison, it is determined whether the signal originated from the conduit.

摘要： An improved method for fracking operations, the improvement comprising measuring the last piece of casing, cutting the casing to the measured length, installing a suspension device on the last piece of casing, landing the suspension device inside the well-head, installing pack-off bushing around the suspension device, engaging locking pins to maintain the pack-off bushing's position, removing blowout preventer, installing a two-way check valve into the mandrel, attaching a multiple pressure rated fracking adapter rated up to twice the pressure rating of the well-head casing, testing the sealing elements of the fracking adapter to insure proper sealing, attaching a fracking valve assembly to the fracking adapter, where an operator fracks a hydrocarbon well for enhanced production without compromising safety by eliminating potential leak points and reducing the costs and time required for preparing and conducting fracking operations and returning the well to production.

摘要： A test sample is extracted from a hydrogen induced cracking (HIC) resistant material candidate. A control sample is extracted from a prequalified HIC susceptible material that is known to suffer predetermined HIC damage when subjected to preset test conditions of a standardized HIC test (e.g., NACE TM0284). The HIC test is performed on the test and control samples. A value of a predetermined cracking criteria is calculated for the control sample. It is determined whether the calculated value of the predetermined cracking criteria is at least equal to a predetermined minimum threshold value. If yes, respective values of a plurality of predetermined HIC resistance criteria for the test sample are calculated. It is determined whether the calculated respective values of the plurality of predetermined HIC resistance criteria for the test sample are not greater than corresponding predetermined maximum threshold values. If yes, the HIC resistant material candidate is qualified as a valid source for sour service applications.

摘要： Systems and methods include a computer-implemented method for determining an integrated surface-downhole integrity score for a natural flow oil well. Wellness surface parameters of a natural flow oil well are determined. Wellness downhole parameters for the natural flow oil well are determined, including parameters indicating well integrity and tubing/casing conditions. An integrated surface-downhole integrity score is determined using the wellness surface parameters and the wellness downhole parameters. An alert is provided for presentation to an operator in a user interface. The alert is provided in response to the integrated surface-downhole integrity score exceeding a threshold.

摘要： A technique facilitates use of sensor data, e.g. pressure data, associated with hydraulic control lines. According to an embodiment, a well string is deployed in a borehole and comprises a tool coupled with a hydraulic control line and operated via hydraulic inputs delivered through the hydraulic control line. Additionally, a sensor is coupled to the hydraulic control line to monitor pressure in the hydraulic control line. The sensor may be located permanently downhole proximate the tool. A control module is configured to collect data from the sensor and to compare the data to a baseline pressure profile associated with the tool. The sensor data may be used to determine characteristics related to operation of the tool.
