A record was set when over 100 selective interval acid treatments were achieved in a Canadian well on a single run using the proprietary PosiFrac Straddle System. In this low fluid level well, the inflatable straddle was coupled with a Fluid Control Valve to maintain the hydrostatic level of the acid column above the tools. The TAM system allows rapid packer deflation and movement to each additional interval without requiring full displacement of the acid. Because this method uses acid as the inflation fluid, it has acid immediately available at the next formation interval to be treated, eliminating the need to bullhead displacement fluids before the acid can start to enter the interval.
