摘要： Compositions are given that have high viscosities at one pH range and low viscosities at another pH range. Methods are given for using such compositions in oilfield treatments. In particular CT wellbore cleanout compositions and methods are given in which a viscous fluid is injected into a wellbore; the fluid entrains particles and carries them to the surface; the viscosity of the fluid is reduced by reducing or increasing the pH; the particles settle from the fluid; the viscosity of the fluid is increased by increasing or reducing the pH; and the fluid is re-injected into the wellbore. Suitable surfactants are anionic surfactants, or mixtures of surfactants containing anionic surfactants, that aggregate into three-dimensional structures that substantially increase the viscosity at high pH but not at low pH. Other suitable surfactants are cationic surfactants with co-surfactants that aggregate below a certain pH but not above.

摘要： A composition and method is given for a well control fluid that is injected into a well during completion or remediation and prevents fluid flow from a formation into the well during operations (such as shut-in, or placement or adjustment of tools/hardware) when no fluid flow is desired. The composition includes a viscoelastic surfactant fluid system (VES) and a decomposable first solid material, preferably in fiber form, that forms a pack or plug in the well at the location where fluid would otherwise leak off, and then decomposes without intervention to release a product that is a breaker for the surfactant or the micelles of the VES. The composition optionally also contains a pH control agent and a second solid (that may also be a fluid loss agent) that affect the decomposition of the first solid.

摘要： A method for stimulating thick or multilayered heterogeneous or homogeneous formations in a single trip without packers involves perforating with tubing conveyed perforation, then injecting a self-diverting acid, then moving the tubing string and perforating at a new location, and then injecting additional self-diverting acid. The sequence may be repeated. The acid is preferably a viscoelastic diverting acid. The self-diverting acid may be alternated with conventional treatment fluid. The job is designed to treat the least permeable zone(s) first and maximizes acid efficiency.
