BioSqueeze - BioSqueeze Process for Eliminating Sustained Annular Pressure
FromBioSqueeze Inc.
The BioSqueeze Process is engineered to permanently eliminate sustained annular pressure in wells by addressing leakage pathways. The sequence begins with operators identifying these pathways using bond logging. A bridge plug is placed, and the casing is perforated to target specific zones susceptible to leakage. The initial step involves injecting a low-viscosity biomineralization solution, designed for minimal environmental impact, downhole through tubing. By applying pressure, this solution is directed into leakage paths for up to six hours. The crew carefully monitors the injection rate and adjusts pressure to ensure the complete elimination of gas migration. The process includes an overnight phase where pressure is maintained to enhance barrier formation. This process is applicable to various well stages, such as Plug & Abandon, Drilled But Uncompleted, and Producing Wells, ensuring a broad application range for sustained annular pressure solutions.Most popular related searches
In most wells, our bottom annular gas squeeze is used to permanently eliminate sustained annular pressure. Here’s how we do it.
- 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.
