摘要： Systems and methods for treating subterranean formations using particulates treated with hydrophobizing agents in aqueous base fluid are provided. In one embodiment, the methods comprise: providing a treatment fluid comprising an aqueous base fluid and at least one particulate treated with one or more hydrophobizing agents; introducing the into a wellbore penetrating at least a portion of a subterranean formation; and using the treatment fluid to drill a portion of the wellbore.

摘要： The present disclosure relates to systems and methods for wellbore pressure control with separated fluid columns. One embodiment is a composition comprising: a base fluid, a hectorite clay, a secondary clay comprising at least one clay selected from the group consisting of an attapulgite clay, a sepiolite clay, a polygorskite clay, and any combination thereof, and a plurality of fibers. Another embodiment is a method comprising: introducing a first fluid into a wellbore; introducing a barrier pill into the wellbore, wherein the barrier pill comprises: a base fluid, a hectorite clay, and a plurality of fibers; and introducing a second fluid into the wellbore. Another embodiment is a method comprising: introducing a first fluid into a wellbore; introducing a barrier pill into the wellbore, wherein the barrier pill comprises: a base fluid, a hectorite clay, and a secondary clay comprising at least one clay selected from the group consisting of an attapulgite clay, a sepiolite clay, a polygorskite clay, and any combination thereof; and introducing a second fluid into the wellbore.

摘要： Compositions, methods, and systems for using particulates treated with one or more hydrophobizing agents in forming filter cakes during drilling to improve filter-cake removal. A method for drilling a wellbore may include circulating a drilling fluid in the wellbore, wherein the drilling fluid comprises particulates treated with one or more hydrophobizing agents; extending the wellbore while the drilling fluid is circulated in the wellbore; and forming a filter cake in the wellbore, wherein the filter cake comprises a portion of the particulates from the drilling fluid.

摘要： A method of inhibiting gas hydrate formation in downhole fluids, including providing a downhole fluid and mixing the downhole fluid with an aqueous gas thermodynamic hydrate inhibitor formulation to form a downhole fluid mixture. A concentration of lithium chloride in the downhole fluid mixture is at least about 1 wt % and a density of the downhole fluid mixture is in a range of about 1.08 to 1.3 gm/cm3 at a downhole temperature of about 50° F. or less and a downhole differential pressure of about 500 psi or higher. An aqueous gas thermodynamic hydrate inhibitor formulation and oil and gas well drilling system including such a formulation are also disclosed.
