    摘要： A method of controlling and delaying the inversion of a drilling fluid and the wettability of a filtercake by using a delayed phase changing agent. The filtercake is preferably formed while drilling a subterranean formation using a drilling fluid includes: an oleaginous fluid; a non-oleaginous fluid; an amine surfactant having the structure: wherein R is a C12–C22 aliphatic hydrocarbon; R′ is an independently selectable from hydrogen or C1 to C3 alkyl; A is NH or O, and 1≦x+y≦3. In the method, the filter cake is exposed to a delayed phase changing agent selected from the group consisting of aliphatic amine acids, salts of aliphatic amine acids and combinations thereof. In one preferred illustrative embodiment, the delayed phase changing agent is delivered in the form of a pill, the pill including a carrier fluid, a viscosifier and the delayed phase changing agent. The delayed phase changing agent may be selected from ethylene diamine tetraacetic acid, alkali metal salts of ethylene diamine tetraacetic acid and combinations of these and similar compounds.

    摘要： A method of cleaning a wellbore prior to the production of oil or gas is disclosed, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake. The method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid includes an aqueous fluid, a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting age, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks.

    摘要： Disclosed herein is a well treatment method comprising the steps of injecting into a well a fluid loss control agent comprising a chelating agent, a viscosity increasing agent, and a plurality of at least partially insoluble bridging solid particles dispersed therein, wherein the chelating agent is effective to at least partially solubilize at least a portion of the bridging solid particles over a solubilizing period of time for thereafter substantially dissolving the bridging solid particles, wherein the solubilizing period of time is controlled by the concentration of the viscosity increasing agent, the concentration of the chelating agent, the composition of the metal salt, the pH of the fluid loss control agent, or a combination thereof. A fluid loss control agent is also disclosed.
