.... It is however, important to optimize many treatment parameters to execute an efficient acidizing job. This study are undertaken to investigate the influences of acid injection rate, acid concentration, variation of rock permeability, reservoir temperature, and acid volume injected on the recovery of damaged...

... of these new fluid-loss additives in making spurt-loss less sensitive to the rock permeability, which in highly permeable rocks yields a more predictable leakoff. This facilitates predictable design and execution of the jobs. Laboratory data also show that the matrix damage caused by the invasion of borate...
