PulseFrac – Formation Stress Testing using Acoustic Shockwaves

Formation Testing

The Problem

Drilling induced formation damage, especially in low permeability reservoirs, cause challenges with regards to measuring accurate formation pressure and acquiring clean reservoir fluid samples.


The Solution

Using the “qWave Pulser” technique in combination with, or as a pre-step to, running a conventional downhole wireline formation tester, to enhance the coupling between the probe(s) of the wireline formation tester and the borehole, as well as enhancing the communication between the borehole and a more virgin formation, for improved measurement/sampling quality.

Value Statement

“qWave is developing an innovative tool to increase subsurface understanding, providing operators critical information for more cost-efficient field development”
