WebApr 1, 2002 · A Diagnostic Fracture Injection Test (DFIT™), also colloquially and sometimes inaccurately called Pre-Frac, Injection Falloff, Data-Frac or minifrac, is a pressure transient test used to obtain ... WebIn an example diagnostic fracture injection test (DFIT), or a "minifrac," a fracturing fluid is pumped at a relatively constant rate and high pressure to achieve a fracture pressure of a subterranean formation. Sometime after achieving formation fracture pressure, the pump is shut off and the well is shut in, such that the pressure within the sealed portion of the well …

WebMini-fracs and DFIT’s are reliable and cost-effective techniques for indirectly measuring the formation’s minimum in-situ stress. During a mini-frac, test fluid is pumped in a short pulse into the reservoir to create a small fracture that cuts through near- wellbore damage to establish communication with the true formation.

Minimum horizontal stress or fracture closure pressure can be obtained from either a diagnostic fracture injection test (DFIT) or by using Eq. (13.14) (if rock properties are available):
WebOverall both methods performed as expected with some exceptions. DTF tended to increase with DIF magnitude and with sample size. The MH/LA method generally showed greater rates of DTF than DFIT. It was also especially sensitive to group distribution differences (impact) identifying it as DTF where DFIT did not.
