摘要： A method includes obtaining a plurality of master sensor responses with a master sensor in a set of training fluids and obtaining node sensor responses in the set of training fluids. A linear correlation between a compensated master data set and a node data set is then found for a set of training fluids and generating node sensor responses in a tool parameter space from the compensated master data set on a set of application fluids. A reverse transformation is obtained based on the node sensor responses in a complete set of calibration fluids. The reverse transformation converts each node sensor response from a tool parameter space to the synthetic parameter space and uses transformed data as inputs of various fluid predictive models to obtain fluid characteristics. The method includes modifying operation parameters of a drilling or a well testing and sampling system according to the fluid characteristics.

摘要： A drilling fluid comprises an aqueous solution; a clay-based component comprising layered silicate; and a viscosifier additive comprising poly(acrylamide-co-diallyldimethylammonium chloride) (poly(AAm-co-DMAC)) polymer. The polymer comprises a number average molecular weight of from 10,000 g/mol to 2,000,000 g/mol. The layered silicate and poly(AAm-co-DMAC) reacts to form a silicate-poly(AAm-co-DMAC) complex within the aqueous solution. A mass ratio of the poly(AAm-co-DMAC) to the layered silicate is 1 to 8.

摘要： Wellbore for extracting heat from magma and a corresponding method. The method includes the steps of drilling a borehole from a surface and towards a magma chamber; supplying a drilling fluid to an interface between a drill bit and a terminal end of the borehole during drilling; terminating the drilling in response to the borehole achieving a predetermined depth; and supplying a thermodynamic fluid into the borehole to maintain the borehole while completing the wellbore. The drilling fluid lifts cuttings out of the borehole and quenches magma to form a solid phase material that can be cut by the drill bit.

摘要： A method of performing a wellbore operation may include circulating an oil-based wellbore fluid having a conductive material therein within a wellbore, the oil-based wellbore fluid having a conductivity of at most 0.02 S/m when measured at 20 kHz; and forming a filtercake having a conductivity at least two orders of magnitude higher than the oil-based wellbore fluid on at least a portion of a wall of the wellbore.

摘要： A method for identifying a wellbore condition includes capturing a first image of cuttings on or downstream from a shale shaker using a first camera. A size, shape, texture, or combination thereof of the cuttings in the first image may be determined. A wellbore condition may be identified based on the size, shape, texture, or combination thereof of the cuttings in the first image.

摘要： A pressure compensator including a housing, an electroactive polymer (EAP) disposed in the housing and defining a volume therein, the volume being changeable upon application of an electric signal. A method for managing pressure in a tool including applying an electrical signal to the pressure compensator and changing a shape of the EAP to change the volume of the compensator whereby the pressure in the tool is altered. A borehole system including a borehole in a subsurface formation, a string in the borehole, a pressure compensator disposed within or as a part of the string.

摘要： In some aspects, the present disclosure includes methods and systems for grounding mobile equipment at a site, such as a hydrocarbon drilling and production site. In one embodiment, the system comprises a mobile unit; one or more ground rods configured to penetrate a portion of a grounded surface; one or more grounding connectors coupled to the one or more ground rods and the mobile unit; and one or more actuators coupled to the mobile unit. The one or more actuators may be used to drive the one or more ground rods into the portion of the grounded surface, thereby creating an electric flowpath to allow for the discharge of electricity.

摘要： A system and method to minimize trips in a wellbore during coiled tubing operations by simultaneously deploying on coiled tubing as part of the bottom hole assembly a wireline tool and an intervention tool. The wireline tool includes a flow through passage to permit a working fluid to flow through the wireline tool to the intervention tool during operations. The intervention tool may be adjusted in real time based on the measurements from the wireline tool.
