... down-hole conditions. It was found that certain ceramic proppants widely used in the Bakken field are vulnerable in weakly acidic fluids (i.e. pH=4). Temperature increases expedite the proppant weakening process. Estimated conductivity loss could be ~50% compared with that treated at neutral pH...

... Abstract As gas storage wells age over time they are susceptible to processes having negative impact on deliverability. The GRI study of 1993 determined that on a national average, 5% of storage deliverability capacity is lost per year. This paper will discuss the successful use of foamed acid...
