... conformance in injection wells. Acid stimulations have been used since the 1940's as a means of improving production, with the first acid fracturing treatments being pumped in the late 1980's. Beginning in I996, these two technologies were combined in an attempt to successfully increase oil production from...

... a tight gas reservoir. The results indicate that the FHT stimulation at 650 °C resulted in a 210% improvement in permeability Tom the baseline undamaged value and 675% improvement from the damaged (water-trapped) value. The post FHT waterflooding of the core still showed 50% improvement in permeability...

... Abstract Mini-frac analysis performed prior to a main fracture treatment is a common procedure for many companies involved in well stimulations. The purpose is to determine instantaneous shut-in pressures (lSIP), fracture closures, and leak-off. If the value for leak-off is high (greater than...

A novel technique, location of two wells at the same point with the steam injection well completed above the hot water well, is used to include steam segregation. The distribution of steam in the reservoir and the effect on production following...
