The Standard BioSqueeze® Process
In most wells, our bottom annular gas squeeze is used to permanently eliminate sustained annular pressure. Here’s how we do it.
Our Process
Click on a step to see how it works.
Operator identifies leakage pathways through bond logging.
Operator places bridge plug and perforates or notches casing to target specific zones where leakage pathways can be accessed.
The first day, the BioSqueeze crew connects its equipment and pumps low-viscosity, environmentally friendly biomineralization solution in position downhole using tubing.
BioSqueeze pumps fluids into problem annuli for about 6 hours, applying pressure to squeeze fluids deep into leakage pathways. Meanwhile, our crew monitors the injection rate and pressure until gas migration is eliminated.
BioSqueeze seals the well in overnight at pressure to continue to form the barrier.
The following day, the BioSqueeze crew returns to continue pumping fluids, ensuring that all problem annuli are fully sealed.
