    摘要: A device for and method of testing fluid compatibility may include placing a first fluid in a fixed-volume testing chamber and placing a second fluid in a sample chamber. The method may also include heating the fixed-volume testing chamber to about a temperature of a subterranean environment and pressurizing the fixed-volume testing chamber to about a pressure of the subterranean environment. The method may further include determining, at a temperature and pressure of about the temperature and pressure of the subterranean environment, a first rheology value of the fluid within the fixed-volume testing chamber, moving a portion of the second fluid from sample chamber into the fixed-volume testing chamber, and determining, at a temperature and pressure of about the temperature and pressure of the subterranean environment, a second rheology value of the fluid within the fixed-volume testing chamber.

    摘要: Cement is conditioned, cured and/or tested while applying a specified temperature and/or pressure. In certain embodiments, the specified temperature and/or pressure applied during the testing substantially simulates anticipated static downhole conditions the cement will be subjected to in use. In certain embodiments, the specified temperature and/or pressure applied during the receiving substantially simulates pumping placement conditions the cement will be subjected to in use. In certain embodiments, the cement can be conditioned in a conditioning vessel while applying specified temperature and/or pressure to the cement. In certain embodiments, the temperature and/or pressure applied in the conditioning substantially simulates anticipated pumping placement conditions the cement will be subjected to in use.

    摘要: Apparatus and methods for determining suitable displacement fluids for use in subterranean cementing operations, and methods of cementing that use such displacement fluids, are provided. Examples of methods include methods of water-wetting an annulus in a subterranean formation having an oleaginous-external/aqueous-internal fluid disposed on at least a portion of one or more surfaces of the annulus. Another example of a method is a method of using an inverter fluid in a subterranean formation that includes a tubular string disposed therein having an annular region adjacent the outer surface of the tubular string, at least part of the annular region having an oleaginous-external/aqueous-internal fluid on a surface thereof. Another example of a method of the present invention is a method of identifying an inverter fluid to use for inverting an oleaginous-external/aqueous-internal fluid in a subterranean formation.
