What is a minifrac?
It is well worth remembering that the industry loves to conflate/obfuscate and often uses unnecessary technical detail to do this.
Frack Off considers fracking to be shorthand for the entire life cycle, supply chain and process of getting oil and gas out of shale. Exploration will lead to Production unless it is opposed, which inevitably requires horizontal drilling and hydraulic fracturing in tens of thousands of wells across large areas of the UK.
A DFIT is a Diagnostic Fracture Injection Test, it involves the introduction of liquid into the well and pressurisation to the point where fractures are created in the target formation (rock). A DFIT or Mini-Frack will require significant pressure so most of the equipment required for full scale HVHF.
HVHF is High Volume Hydraulic Fracturing usually involving Slick Water (chemical additives) and Propants (sand to hold the fractures open) and may involve multiple stages (multiple target formations). HVHF is qualified by the use of more than 1 million gallons of fluid.
