Step injection, immediate filling Explanation: Airlift pumping (a break in drilling will be about 8–12 hours) is a priority technique at watery intervals. Step injection (a break in drilling will be about 4-6 hours) is a priority technique at the least watery intervals. Immediate filling (a break in drilling will be about 4-6 hours) is a backup option. |

The step-rate injectivity test, instant loading Explanation: The step-rate injectivity test (aka step-rate test, injectivity test, fracture step rate test, step rate injection test) is a common test used to estimate the threshold pressure at which fractures are opened in the injected formation and/or the overlying or underlying beds. http://www.dunnhydrogeo.com/home/injection-well-testing-nt Figure 8.6: Fluid loading of a hollow cylinder (after Rice and Cleary, 1976, p. ... then yield the undrained stresses at the instant of loading https://books.google.com.ua/books?id=4GfVDQAAQBAJ&pg=PA207&l... -------------------------------------------------- Note added at 8 days (2018-10-31 13:41:46 GMT) Post-grading -------------------------------------------------- Большое спасибо, Елена! |
