Abstract: Methods and systems for removing a gel from wellbore equipment. An example method includes introducing a cleaning fluid into the wellbore equipment comprising the gel disposed therein or thereon. The cleaning fluid includes a brine having a total dissolved solids concentration of between about 30K ppm to about 300K ppm. The method further includes contacting the gel with the cleaning fluid in the wellbore equipment, and removing the gel and the cleaning fluid from the wellbore equipment.

Abstract: A method for protecting a wellbore includes identifying a parent wellbore and a child wellbore and identifying a parent well stage along the parent wellbore that has the potential to interact with a child well stage along the child wellbore while the child well stage undergoes hydraulic fracturing. The method further includes pumping a treatment fluid downhole to the parent well stage for pressurizing the parent well stage to a pressure that is equal to or greater than the pressure in the child well stage while the child well stage undergoes hydraulic fracturing and maintaining the pressure in the parent well stage that is equal to or greater than the pressure in the child well stage while the child well stage undergoes hydraulic fracturing.

Abstract: Selecting a fracing-plan-to-apply to optimize a complexity index includes identifying a set of controllable input variables that defines a fracing plan. Initial values for the set of controllable input variables are defined. The initial values of the set of controllable input variables are processed to produce an initial stimulated geometry. A complexity estimator is applied to the initial stimulated geometry to produce an initial complexity index, which is evaluated to identify at least one variation from the initial values, which is processed to produce a variation stimulated geometry for each of the at least one variation from the initial values. The complexity estimator is applied to the at least one variation stimulated geometry to produce a variation complexity index for each of the at least one variation from the initial values. The fracing-plan-to-apply is selected from among the initial values and the at least one variation from the initial values.
