Keep your valuable resources from escaping by sealing problem leaks at their source. BioSqueeze®'s biomineralization solution can seal any leakage pathways effectively, allowing you to retain more of your profit from gas storage wells. Without no need to drill out before or after, you'll save time money by using the most effective solution first.
BioSqueeze® uses a Bottom Annular Gas Squeeze to seal methane leaks in gas storage wells, shown below.
Downhole BioSqueeze®
Operator Preparation
Step 1:
Identify problem annulus through bond logging.
Step 2:
Place bridge plug and perforate or notch casing to target leakage pathways.
Step 3:
Set packer and run tubing to bottom perf/notch to squeeze into the annulus.
BioSqueeze® Execution
Step 4:
The first day, connect equipment and pump low-viscosity, environmentally friendly biomineralization solution in position downhole using tubing.
Step 5:
Pump fluids into problem annuli for about 6 hours, applying pressure to squeeze fluids deep into leakage pathways. Monitor injection rate and pressure until gas migration is eliminated.
Step 6:
Seal the well in overnight at pressure to continue to form the barrier.
Step 7:
The following day, return to continue pumping fluids, ensuring that all problem annuli are fully sealed.
