Step rate test injection
網頁1995年3月19日 · SPE MembersAbstract. Step-rate injection tests are frequently performed in water injection wells for waterflooding reservoirs and in mini-fracture tests for stimulation treatments designs. In both applications, the data are usually analyzed to determine the fracture propagation gradient. To enhance the usefulness of step-rate test data, the … 網頁2024年3月22日 · One is presented in this paper using a step-rate test. The paper uses modified Eaton's equations that are representatives of interest. The modified equations are used to estimate parameters of the minimum horizontal stress, fracture-extension gradient, overburden, and Poisson's ratio.
