The present invention discloses an active intelligent wellbore pressure control system, which includes a ground multi-parameter online monitoring system (86), a rotary blowout preventer (1), a wellhead back pressure compensation manifold, an automatic plugging material filling device (62), a drilling device, an MPD intelligent control system (87), a remote monitoring and control system (88), and a high-precision hydraulic calculation system (105). The present invention provides a wellbore pressure control thought of “plugging and control integration”, improves the pressure resistance of a formation by circularly plugging while drilling, realizes active control of a wellbore pressure, effectively broadens a “drilling safety density window” of the formation, reduces the requirements on the pressure control precision of a wellbore pressure control device, solves the problem that a conventional MPD technology cannot deal with the situation that the “drilling safety density window” of the formation is extremely narrow or even zero, and expands the application range of the MIPD technology.

In an embodiment, a sample conditioning system includes a first valve subsystem, a controller, and a signal generator. The first valve subsystem includes a first electrically activated valve and a first timed switch in electrical communication with the first electrically activated valve, where the first timed switch is configured with a first time duration. The controller is configured to receive drilling data from a data source and, responsive to the drilling data satisfying a trigger associated with a timed sequence, cause the signal generator to apply a signal to at least the first timed switch. The signal causes the first timed switch to close for at least the first time duration and power the first electrically activated valve, the powered first electrically activated valve switching to allow air from a first air line to pass therethrough to a sample line.

The disclosure provides for systems and methods for removing particle settlement in a heater system. The method includes introducing a fluid into a first heater of the heater system, wherein the first heater is operable to increase the temperature of the introduced fluid. The method further includes actuating a first air agitation unit to discharge a volume of compressed air into the first heater, wherein the compressed air is configured to provide mixing and suspension to particles settled within the first heater through the velocity and expansion of the compressed air to atmospheric pressure. The method further includes discharging a mixture from the first heater comprising the fluid and the particles from the first heater and directing the discharged mixture to a return point in a flow path.

A drilling system for drilling a borehole. The drilling system includes a drilling fluid pump operable to circulate fluid through the borehole and a fluid analysis system to analyze returned fluid from the borehole. The fluid analysis system includes a sensor system, a recirculation system, and a control system in electronic communication with the drilling fluid pump and the recirculation system. The sensor system is operable to measure one or more properties of the returned fluid. The recirculation system includes a pump and controllable valves and is operable to control flow of the returned fluid through the fluid analysis system.

A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

A gas extraction system comprising a heater configured to receive a wellbore servicing fluid sample and discharge a heated wellbore servicing fluid sample, wherein the heater comprises an internal heat exchange surface coated with a superhydrophobic coating composition; a gas extractor configured to receive at least a portion of the heated wellbore servicing fluid sample and extract an extracted gas from the heated wellbore servicing fluid sample; and one or more detectors configured to receive at least a portion of the extracted gas and provide an analysis of the extracted gas.

A separator system and method may provide a four-way separator that may separate a material and remove a hazardous material. The hazardous material may include gas and sand that may be removed by the four-way separator. The separator system and method may further provide a main unit that may include three chambers or recirculation hoppers, an auger sand extractor, and a strap tank. The separator system and method may provide a faster rig-up time and may be exclusively driven by hydraulics.

A system and method for analyzing a gas in a drilling fluid involves a degasser operable to separate the gas from the drilling fluid. A gas analyzer in fluid communication with the degasser receives a sample of the separated gas and determines a property of the gas. A controller in communication with the gas analyzer automates the operation of the gas analyzer by adjusting a parameter of the separated gas sample as the gas sample is supplied to the gas analyzer.

A method for analyzing a drilling fluid receiving a drilling fluid sample from a flow of the drilling fluid at a surface of a borehole being drilled in a subterranean formation and extracting, using a gas extraction and sampling system, a dissolved gas from the drilling fluid sample. The method includes determining, using a gas chromatograph, a concentration over time of at least one chemical species of a dissolved gas from the drilling fluid sample and generating an area per concentration curve based on the concentration over time. The method includes determining, using a gas extraction and sampling system, at least one concentration value of the at least one chemical species of the dissolved gas from the drilling fluid sample and correcting bias caused by the gas extraction and sampling system, wherein correcting the bias comprises modifying the at least one concentration value based on the area per concentration curve.
