Encapsulated breakers vs. oxidizers: Which is best for Guar Gum fluids?

One factor that influences the success of hydraulic fracturing is the selection of fracturing fluid and its additives. Some additive can cause any residue after it's added to base fracturing fluid. This residue can plug the pore throat and decreasing permeability in invaded zone. This research was conducted using compatibility test between Guar Gum based fracturing fluid and boron as crosslinker and three type of breaker. The types of breaker used include oxidizer, acid, and encapsulated breaker. The research was conducted by mixing the fracturing fluid with its additive at a certain concentration and then settling it in a water bath until it breaks, then filtering, drying, and weighing the resulting residue. the results shows that 40 system of of guar gum fracturing fluid is compatible with the 0.2% boron crosslink and 0.4% oxidizer breaker with total dry residue 0.59 g and 4.66% if its compare to Guar Gum weight.
