BioSqueeze on Five Horizontal Producing Wells

The Problem

Producing Wells with Bradenhead Pressure Ranging from 80 psi to 899 psi

BioSqueeze Inc. was contracted by an operator in the DJ Basin of Colorado to remediate high Bradenhead Pressure on several of their horizontal producing wells. These wells had Bradenhead pressures ranging from 80 psi to almost 900 psi. An advanced cement bond log was used to identify an appropriate location on each well to perform a BioSqueeze. Preparation consisted of a rig crew setting a bridge plug, perforating the well, and placing tubing. The workover rig was then moved to the next well. We then connected hoses from our trailer to the wellhead to begin our sealing process.

The Solution

Bradenhead Pressure Completely Eliminated, All Five Wells Placed Back Into Production

While pumping fluids, the pressure and injection rate were monitored as shown in Figure 1. Fluids were pumped at constant pressure and the injection rate dropped over time, indicating sealing of fractures and micro-annuli in the cement and associated zones. After determining that the injection zone was plugged, the equipment was moved to the next well. This process was then repeated for all five wells.

BioSqueeze reduced the Bradenhead pressure on all five producing wells to 0 psi. Each well passed mechanical integrity tests with no additional intervention and were subsequently placed back into production.
