D65: Resources Applications for Oil and Gas Reservoirs

Planning a Water Disposal well application? Disposal refers to the injection of fluids for purposes other than enhanced recovery or gas storage. It is not desirable for water disposal wells to exceed the formation fracture pressure because of possible isolation problems. We therefore recommend a Mini-Frac’ (#DFIT) and Fall-off test, conducted with subsurface pressure recorders (over a Step-Rate test) to optimize your maximum wellhead injection pressure (MWHIP). For facility design, economics, and reservoir engineering we also recommend an injectivity test. Notwithstanding, if you are not providing formation fracture test data, you will use a generic chart provided in #AER Directive 51, Appendix 5. Not the best solution…
