    摘要： A variety of methods are disclosed, including, in one embodiment, a method comprising: applying a wettability modifier coating on a surface of a downhole tool; disposing the downhole tool into a wellbore extending into a subterranean formation, wherein the wettability modifier coating is disposed on the surface of the downhole tool; traversing the wellbore with the downhole tool; and removing the downhole tool from the wellbore.

    摘要： A method for evaluating and optimizing scale management at a subsurface for improved well performance may include performing multiple first tests, where each first test combines a first fluid with a second fluid, wherein the first fluid comprises a concentration of a scale inhibitor and a chemistry of additional fluid components. The method may also include identifying an optimal mixture of the first fluid among the first tests, where the optimal mixture comprises a minimum concentration of the scale inhibitor that reduces scale deposition. The method may further include performing a second test that combines the first fluid with the scale inhibitor, the second fluid, and rock. The method may also include evaluating a concentration of the scale inhibitor in aqueous phase after a period of time after initiating the second test. The method may further include identifying a target fluid for use in a field operation at the subsurface.

    摘要： Chemical stick receiving pressure vessel includes a housing having a body portion. Body portion forming a first opening at a first end and forming a second opening at a second end. Cap operable to close the first opening, wherein the cap forms an outlet. Plurality of stick receiving tubes mounted inside the body portion, wherein the stick receiving tubes are operable to receive chemical treatment sticks; a base portion being coupled to the second opening, wherein the base portion is operable to be placed on the ground and within a predefined proximity to a wellhead. Inlet formed on the side surface of the base portion. Fluid enters the inlet from the well-head and passes through the plurality of stick receiving tubes before exiting through the outlet to be placed in the annulus between the casing and tubing of the wellbore.
