摘要： A system can flush a drilling fluid sample with a hydrocarbon blend, which includes a determined concentration of at least one chemical species to generate a flushed drilling fluid sample. The system can extract a dissolved gas from the flushed drilling fluid sample. The system can determine a concentration over time of at least one chemical species of the dissolved gas. The system can generate an area per concentration curve based on the concentration over time of the at least one chemical species. The system can determine at least one concentration value of the at least one chemical species. The system can modify the at least one concentration value based on the area per concentration curve. The system can then correct bias caused by the gas extractor and fluid sampling system.

摘要： A precise deep oil and gas navigation system based on structural evaluation of a sand/shale formation, and a device are provided. The precise deep oil and gas navigation system is implemented by: acquiring basic data of a target well location as well as basic data and an acoustic LWD curve of an adjacent well; dividing a basic data group; retaining extremely strongly correlated data and strongly correlated data of the basic data group, and performing dimensionality reduction; constructing a three-dimensional fusion feature data volume based on a dimensionality-reduced fusion feature parameter and a time-frequency spectrum; predicting a missing curve according to the three-dimensional fusion feature data volume; and correcting a stratigraphic structure model based on the missing curve to guide the design of a drilling trajectory.

摘要： A system includes a dispensing device having a material chamber to store an oilfield material and to fluidly couple to a wellhead, a plurality of flow control devices to control a flow of the oilfield material via the material chamber, a plurality of sensors to measure one or more properties related to the dispensing device, and a control system communicatively coupled to the dispensing device. The control system opens a first flow control device to fill the material chamber with the oilfield material, monitors a condition associated with the material chamber based on the properties measured via the plurality of sensors, opens a second flow control device to provide a high pressure fluid into the material chamber when the condition is present, and open a third flow control device, where the third flow control device fluidly couples the material chamber to the wellhead.

摘要： Methods of the present disclosure may include obtaining an origin fluid having a calcium concentration of about 1.5 M or greater. A treatment fluid may be created by introducing an amount of slaked lime to the origin fluid to change a pH of the resulting treatment fluid to about 11 or greater. The treatment fluid may be introduced into a subterranean formation containing a formation gas comprising natural gas and carbon dioxide. The calcium in the treatment fluid may be allowed to react with the carbon dioxide within the subterranean formation to form calcite. The treated formation gas may be removed from the subterranean formation after the formation of calcite, wherein the concentration of carbon dioxide in the treated formation gas is lower than the formation gas before it was contacted with the treatment fluid.

摘要： The present invention provides a multi-phase controlled multi-well pumping unit and relates to an oil exploitation device. The multi-phase controlled multi-well pumping unit includes: a power part, where include a rotating shaft; a crank part, where the crank part includes two crank mechanisms, and a power output part, where the power output part includes a plurality of flexible-power-rope guide components. The pumping unit drives the dual cranks by two ends of the rotating shaft to serve as a power source, and the dual-crank power output mechanism leads out a plurality of groups of flexible power ropes to drive, by using the uniformly distributed guide components, a plurality of pumping wells to operate. Such practice can effectively reduce energy consumption of the multi-well pumping unit system and further improve efficiency.

摘要： A method for installing a dual/multiple lateral well where the overburden casing is relatively narrow includes drilling a single diameter bore for the first lateral and employing a tapered liner. The liner has a narrow production section (109) and a larger diameter proximal section (104). A hollow whipstock (113) is run into the well and a window is milled in the proximal section (104) of the tapered liner, allowing a branched lateral B (115) to be drilled and then a liner (116) run through it.

摘要： A method for providing a permanent barrier in a well includes lowering a first, particulate constituent of a pyrotechnic mixture to a desired location in the well, wherein the first constituent is a metal oxide. The method further includes waiting a first predetermined period of time to allow the first, particulate constituent to settle as sediment at the desired location, lowering a second constituent of the pyrotechnic mixture to the desired location in the well, wherein the second constituent is a metal, and igniting the pyrotechnic mixture to start a heat generating exothermic reduction-oxidation process.

摘要： A wellhead assembly includes a production tree, a sacrificial fluid control assembly, an adaptor assembly, and a sleeve. The sacrificial fluid control assembly is fluidly coupled to the production tree. The adaptor assembly resides between the production tree and the sacrificial fluid control assembly. The adaptor assembly forms, with the adaptor assembly attached to the production tree and the sacrificial fluid control assembly, a common bore. The sleeve is disposed within the common bore and extends from the adaptor assembly to the tubing spool. The sleeve includes i) a first end that forms, with the adaptor or the sacrificial fluid control assembly, a first fluid seal, and ii) a second end opposite the first end and forming, with the tubing spool, a second fluid seal such that the sleeve fluidly isolates a first section of the common bore from a second section of the common bore.

摘要： A closing unit system for a blowout preventer (BOP) stack includes a first fluid reservoir, a first power source, a first pump system fluidly coupled to the first fluid reservoir and electrically coupled to the first power source, and a valve manifold fluidly coupled to the first pump system via a closing unit hose assembly and configured to couple to the BOP stack. The closing unit system also includes one or more processors that are configured to receive an input indicative of an instruction to adjust an actuator associated with the BOP stack, and instruct the first power source to provide power to the first pump system to cause the first pump system to pump a fluid from the first fluid reservoir to the valve manifold in response to the input.
