Doing so will l ead to properly designed hydraulic fracturing treatments, realistic predic tions of well performance, and a basis for normalizing reservoir contribut ion when evaluating completion and stimulation effectiveness. \r\n \r\n \r\n \r\n A time-honored way to derive the necessary reservoir informatio n is to conduct in-situ pressure transient tests. Since it is difficult t o inject fluid into or withdraw fluid from the pore network of ultra-tight rock, hydraulic fracture propagation can be used to provide the injection event. A hydraulic fracture bypasses wellbore damage and near-wellbore s tress concentrations and connects wellbore to a significant portion of the reservoir layer thickness. Evaluating the pressure falloff response of s mall-scale hydraulic fractures enables reservoir transmissibility (kh/u) t o be evaluated by a variation of the impulse testing method. As well, the minimum principle stress is derived by identifying fracture closure. \ r\n \r\n \r\n \r\n Consequently, diagnostic fracture injection testing (DFIT) has been used extensively in unconventional reservoir plays to gain insight into stress and transmissibility - yet with mixed results. The p resenter will briefly outline the basic theory and implementation process of DFIT and then discuss practical considerations that strongly influence the value we derive from these tests. Examples will be used from DFIT pro jects in Eagle Ford, Bakken and Poland.
