Reducing Friction Pressure with Hydrajet Perforating During Proppant Fracturing

摘要

During proppant fracturing treatment, it is imperative that adequate perforation channels link the wellbore to the formation. Entry friction (near-wellbore and perforation) is a critical issue that can worsen as the result of poor perforation channels. Excessive entry friction results in high surface treating pressures, which in turn can lead to a premature screen-out. The conventional method of perforating using a shape charge explosives has inherent disadvantages. These disadvantages can contribute to bottom-hole friction in a multitude of ways.
