Mini Fracture Test

What Does Mini Fracture Test Mean?

A mini fracture test is conducted to assess wellbore conditions and to determine essential geological properties on a trenchless construction site. Analysis of test results will influence the design of the excavation project.

A mini fracture test is sometimes referred to as a minifrac test.

Trenchlesspedia Explains Mini Fracture Test

Along with in-situ and step-down tests, mini fracture testing is part of the geological evaluation of a planned trenchless site. The objective is to gain a better understanding of potential geotechnical challenges of the trenchless operation.

A mini fracture test involves the creation of short fractures through fluid injection, followed by close observation of the fracture system. This is generally done ahead of any main fracture treatments.

A number of values can be determined as the pressure falloff is recorded. These include: fracture closure pressure, net fracture pressure, fluid efficiency, and fracture gradient. The analysis of all this data is accomplished through highly advanced computing techniques.
