... Glasscock East Unit (HGEU). Tiltmeter mapping was used to determine the existence, orientation, and geometry of created hydraulic fractures, as well as, the dependence of fracture length on the water injection rate. Tiltmeter fracture mapping identified that hydraulic fracturing occurs even at very low...

.... While these fluids are more effective than straight HCl (especially at high temperatures and low injection rates), additional injection strategies can be used to increase the depth of penetration and, in turn, improve skin reduction. Injection strategies such as increasing the injection rate...

... Introduction Acidizing in horizontal wells is significantly different than in vertical well. In a horizontal well, formation contact area is much longer, and acid distribution inside the wellbore is a greater issue 1 . The acid injection rate per length of formation treated is also generally much lower...

... Production: As Unit water injection rates increased, producing well water cuts increased accordingly. Water production increased to about 11,000 BWPD in early 1993. Water Injection: Peak water injection rates were approximately 30,000 BWIPD in October, 1989 – a little over two years from...

Knowing this information will assist in optimizing recovery by reducing injection rates in wells to control cycling (i.e. prevent fluids from...
