Publication number: 20170298266Abstract: A well treatment method includes forming a well treatment fluid by combining ingredients including a polymer, a crosslinker, an acidifying substance, and a base fluid. Crosslinking increases viscosity of the fluid during a development time. A pH decrease is controlled during the development time using the acidifying substance. The method also includes delaying the development time of the viscosity increase by controlling the pH decrease. A well treatment method includes forming a well treatment fluid by combining ingredients including a hydratable polymer, a crosslinker, an acidifying substance, and a base fluid. The method includes delaying development time of a viscosity increase by controlling a pH decrease without adding further acidifying substance after combining the polymer, crosslinker, acidifying substance, and base fluid. A well treatment fluid formulated with ingredients include a base fluid, a polymer, a crosslinker, and an acidifying substance.Type: ApplicationFiled: July 5, 2017Publication date: October 19, 2017Inventors: MAGNUS U. LEGEMAH, PAUL S. CARMAN, RUPA VENUGOPAL, HONG SUN

Patent number: 8636066Abstract: A well treatment fluid containing borated galactomannan may be used to isolate a productive zone in a well having multiple productive zones. The fluid is particularly useful in treatment of wells containing a mechanical zonal isolation system in the productive zone of interest. The fluid is pumped into the well in a substantially non-hydrated form. The well treatment fluid is therefore highly effective in preferentially sealing or blocking productive zones in the formation since delayed hydration of the fluid may be controlled for up to several hours.Type: GrantFiled: March 12, 2010Date of Patent: January 28, 2014Assignee: Baker Hughes IncorporatedInventors: D. V. Satyanarayana Gupta, Marshall G. Ault, Rupa Venugopal
