Abstract:
Methods including precipitated and mined calcium carbonate lost circulation materials for use in subterranean formation operations. The precipitated calcium carbonate lost circulation materials are formed under a chosen set of precipitation conditions, including in situ in a subterranean formation. The mined calcium carbonate lost circulation materials are obtained in a desired morphological form under naturally occurring mined conditions. The precipitated and mined calcium carbonate lost circulation materials may be needle-shaped aragonite having an aspect ratio of about 1.4 to about 15.

Abstract:
Among the methods provided is a method comprising: providing an oil-based fluid formed by combining components that comprise a glycol ether additive comprising a glycol ether, wherein the glycol ether additive substantially increases the low-shear viscosity of the oil-based fluid at temperatures between approximately 120 degrees Fahrenheit (48.9 degrees Celsius) and 500 degrees Fahrenheit (260 degrees Celsius); and using the oil-based fluid to drill at least a portion of a well bore penetrating at least a portion of a subterranean formation.

Methods Of Cleaning Invert Emulsion Drilling Fluids
Various embodiments disclosed relate to methods of cleaning invert emulsion drilling fluids. In various embodiments, the present invention provides a method of cleaning a drilling fluid. The method includes cleaning a used invert emulsion drilling fluid that includes drilled cuttings to form a cleaned invert emulsion drilling fluid. The cleaning includes processing the used invert emulsion drilling fluid in a separator to remove at least some of the drilled cuttings therefrom.
Resilient Carbon-Based Materials As Lost Circulation Materials And Related Methods
Highly resilient carbon-based materials having a resiliency greater than about 120% at 10,000 psi may be useful as lost circulation materials (LCMs) for wellbore strengthening and lost circulation mitigation in downhole operations in subterranean formations with depleted zones. For example, a downhole method may include drilling at least a portion of a wellbore penetrating a subterranean formation with at least one depleted zone having a plurality of fractures extending from the wellbore into the at least one depleted zone; circulating a treatment fluid through the wellbore, the treatment fluid comprising a base fluid and a resilient carbon-based material having a resiliency greater than about 120% at 10,000 psi; contacting the at least one depleted zone with the resilient carbon-based material; and plugging at least some of the plurality of fractures in the at least one depleted zone with the resilient carbon-based material.
