The Friction Measuring Tool: Real-Time Estimates of Sandface Pressure During Fracture Treatments

Abstract: This paper describes a Friction Measuring Tool (FMT) and how it is used to estimate pressure loss from friction in the wellbore while a foam fracture treatment is being pumped. Combined with standard surface equipment, such as densitometers, flowmeters, and pressure transducers, this tool (located on the surface) offers real-time estimates of bottomhole treating pressures during the fracture treatment. Field examples are presented comparing calculated bottomhole treating pressures, based on the FMT, to actual … Show more

“…In the 1990s, a friction-measuring tool (Graham et al 1994) was designed for fracture-treatment operations that used foam. The friction loss of the foam before entering the wellbore was measured by measuring the pressure drop in a short piece of pipe downstream of the foam-generation point.…”
