Additional embodiments of the present disclosure pertain to methods for logging a subterranean well by utilizing the aforementioned wellbore fluids.
Abstract:
A method for onsite bacteria testing for oil and gas applications including collecting at least one component of a wellbore fluid; exposing at least one contaminant in the at least one component to at least one substrate that produces a detectable moiety; and performing a quantitative or qualitative detection of the detectable moiety.
Abstract:
Electrically conductive oil-based wellbore fluids and methods of using same are provided. Wellbore fluids provided may contain one or more carbon nanotubes, where the one or more carbon nanotubes have a particular d/g ratio as determined by Raman spectroscopy. Also provided are methods for electrical logging of a subterranean well that include emplacing a logging medium into a subterranean well, wherein the logging medium contains a non-aqueous fluid and one or more carbon nanotubes, where the one or more carbon nanotubes are present in a concentration so as to permit the electrical logging of the subterranean well; and acquiring an electrical log the subterranean well.
Abstract:
A method of controlling the vibration of a vibratory separator, the method including providing a vibratory separator having a frame and a plurality of force generators coupled to the frame and a control unit operatively connected to each of the plurality of force generators, and independently controlling each of the plurality of force generators. Independently controlling each of the plurality of force generators controls a motion profile of the vibratory separator.
Abstract:
A method includes running a downhole tool into a wellbore, operating the downhole tool in a suction mode and removing debris from the wellbore, and operating the downhole tool in a circulation mode. A tool includes a body sub, a debris sub coupled to the body sub, a suction sub disposed in the debris sub, an annular jet pump sub disposed in the body sub and in fluid communication with the suction tube, and a seal sub disposed in the annular jet pump sub and configured to move from a first position to a second position. The tool operates in a first mode when the sea sub is in the first position and in a second mode when the seal sub is in the second position.
Abstract:
In a method of gravel packing a wellbore in a subterranean formation, the wellbore comprising a cased section and an uncased section, the method may include pumping into the wellbore a gravel pack composition comprising gravel and a carrier fluid comprising an invert emulsion fluid, where the invert emulsion fluid may comprise: an oleaginous external phase; a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50 and an emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase.
Abstract:
A breaker fluid composition and methods for using said breaker fluid composition are provided, where the breaker fluid includes a non-aqueous base fluid, a precipitated silica, an acid source, and, in some embodiments, a chelant.
Abstract:
Wellbore fluid compositions containing a base fluid; at least one synthetic fiber; and a particulate solid; where one or more of the at least one synthetic fiber and the particulate solid are completely or substantially acid soluble are provided. In another aspect, methods of reducing loss of wellbore fluid in a wellbore to a formation are provided, including: introducing into the wellbore a fluid composition comprising one or more synthetic fibers and one or more particulate solids.
Abstract:
A method for testing a loss control material, the method including filling a testing environment in a testing system with a first fluid, injecting a loss control material in a second fluid into the testing environment from a first end of the testing system, thereby displacing the first fluid across the testing environment to a second end of the testing system, and monitoring a formation of a barrier created by the loss control material.
Abstract:
A scalping insert includes a scalping surface having a plurality of scalping slots therethrough, and a vertical base portion. A shaker screen assembly includes a screen frame having at least one slot, and at least one scalping insert disposed in the at least one slot of the screen frame. A method of processing fluid includes providing a flow of fluid to a shaker screen assembly; and flowing the fluid through a scalping surface and a screen surface of a single shaker screen deck.
