What is BioSqueeze^®?

BioSqueeze^® uses a low-viscosity, environmentally friendly biomineralizing solution to seal even the smallest leakage pathways, which no other technology can reach. Once in place, it forms a gas-tight crystalline calcium carbonate seal – similar to limestone – that readily bonds to rock, cement, and steel, permanently sequestering escaping gases at their source. BioSqueeze^® harnesses the process of biomineralization in a new, innovative way, using naturally-occurring soil bacteria to create new minerals that solve problems for the oil and gas industry.

 

Biomineralization: A natural, effective way to stop methane leaks.

BioSqueeze Inc. is the world leader in biomineralization – the process by which living organisms produce minerals. Biomineralization is a safe, environmentally friendly technology that’s at the core of the BioSqueeze^® solution and all of our applications.

 

How Does Biomineralization Work?

1. Biomineralization combines non-hazardous, naturally occurring soil bacteria and common, widely available, and safe chemicals used as food additives, fertilizers, and agricultural feed products. Together, they create a fluid with the ability to transform into new minerals.

2. This environmentally friendly mineralizing solution is pumped deep into leakage pathways of a well. With a viscosity of 1.05 cP – similar to water – our solution can easily penetrate tiny micro-annuli that no other product can reach, sealing leaks at their source.

3. Once in place, the fluid begins its transformation into crystalline calcium carbonate – a limestone-like material that binds to rock, cement, and steel, permanently sealing any and all leakage pathways.

4. Crystal formation persists for several hours after the organisms become inactive, quickly creating an impermeable and permanent seal. Once solid, the calcium carbonate is stronger than the existing formation.

 

The Result: The Most Effective Solution For Stopping Methane Leaks

Using biomineralization, BioSqueeze^® creates a cost-effective, permanent seal, eliminating sustained casing pressure consistently. For those pioneering stewardship of the Earth, BioSqueeze^® is carbon neutral, from production to sealing. Due to its natural composition, it can be used safely where other solutions can’t, including sensitive areas near aquifers and water tables.

 

Our Process:

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.

1. Operator identifies leakage pathways through bond logging.

2. Operator places bridge plug and perforates or notches casing to target specific zones where leakage pathways can be accessed.

3. The first day, the BioSqueeze crew connects its equipment and pumps low-viscosity, environmentally friendly biomineralization solution in position downhole using tubing.

4. 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.

5. BioSqueeze seals the well in overnight at pressure to continue to form the barrier.

6. The following day, the BioSqueeze crew returns to continue pumping fluids, ensuring that all problem annuli are fully sealed.

b) Drilled But Uncompleted (DUC) Wells

Eliminate Sustained Casing Pressure in DUC Wells

Oil and gas wells that have been drilled but have not yet undergone various completion activities are often compromised by annular leaks. Pressure from these leaks continues to build over time, with the risk of a blowout unless vented or flared. BioSqueeze^® can help operators avoid band-aid solutions, eliminating sustained casing pressure in very few attempts, foregoing the need for maintenance down the road. Since BioSqueeze^® seals leakage pathways themselves and leaves nothing in the wellbore, no-drill out is needed after the job is done, saving operators time and money.

BioSqueeze^® can eliminate sustained casing pressure in DUC wells using a Bottom Annular Gas Squeeze, shown below.

Downhole BioSqueeze^®

c) Producing Wells

Eliminate Bradenhead Pressure in Producing Wells

Wells that currently produce oil and gas can create unwanted bradenhead pressure (sustained casing pressure), resulting in methane emissions. BioSqueeze^® can seal leakage pathways so that the well can keep producing at a high rate, without unnecessary emissions escaping in the process. Since BioSqueeze^® seals leakage pathways themselves and leaves nothing in the wellbore, no drill out is needed after the job is done, saving operators time and money.

Methane leaks in oil and gas wells cost the industry millions of dollars in unsuccessful attempts to seal while taking up precious time and resources. Historically, technologies for eliminating sustained casing pressure have been inconsistent, expensive, and inefficient. BioSqueeze^® sets a new standard as the most effective and environmentally friendly solution for stopping gas migration.

BioSqueeze^® answers the call with a cost-effective solution that seals even the toughest leaks at a single flat rate.

Eliminate Sustained Casing Pressure, Once and For All

BioSqueeze Inc. has successfully sealed leaks in nine U.S. states and two Canadian provinces – often eliminating leaks in multiple annuli in a single application. BioSqueeze^® has been used in P&A, DUC and producing wells, as well as gas storage and sequestration wells. Avoid paying for another round of drill out and cement, costing hundreds of thousands of dollars and tying up crews for months on end. If we don’t stop the leak on our first attempt, we will work with your team until the problem is solved.

 

Why Choose Biosqueeze^®?

• Sealed Well

BioSqueeze^® routinely seals multiple leaks in a single application – often after dozens of other attempts using cement and resins have failed and millions have already been spent. BioSqueeze^® does the job right, the first time.

• Superior Penetration

Low viscosity (1.05 cP) fluids seal even the smallest leakage pathways (as small as 1 micron or 0.00008 inches wide), which no other technology can reach.

• Permanent, Gas-Tight Seal

BioSqueeze^® forms crystalline calcium carbonate similar to limestone in leakage pathways, readily bonding to steel, cement, and the formation to create an impermeable seal that prevents leaks once and for all.

• No Drill Out Necessary

BioSqueeze^® forms a seal in the leakage pathways themselves, not the wellbore, leaving nothing to drill out after the job is done.

• Green Technology

BioSqueeze^® uses natural and safe biomineralization technology, which poses no risk for aquifer contamination and generates less than 1/3 the amount of CO² as a traditional cement squeeze.

• Abundant Applications

BioSqueeze^® seals leaks to eliminate annular casing pressure in a wide variety of wells, before or after other attempts to seal and across a wide range of temperatures, pressures and depths. BioSqueeze^® can also be used in refracturing and enhanced oil recovery to utilize more of a well's potential.

 

 

A). MacroSeal^™

In applications where cement bond is poor but present remedial cementing can be ineffective as placement may be impossible, cement can be gas cut before it sets, and the frac gradient is often exceeded thus exacerbating existing integrity issues by creating additional leakage pathways.

MacroSeal^™ is a low-viscosity fluid system that rapidly crystalizes to form an impermeable, limestone barrier stronger than existing cement. MacroSeal^™ can be injected into poorly cemented intervals, is impervious to gas cut, and is placed with precision pumping systems that ensure the frac gradient is not exceeded making it a more effective solution for restoring cement integrity.

4x More Successful than Cement

 

 

 

B). MicroSeal^™

In applications where leakage pathways are too tight for remedial cementing alternative sealants like resins and micro-fine cements can be ineffective due to their inability to access all leakage pathways and shrinkage that occurs during setup allowing gas to circumvent the new barrier, with the status quo being repeated remediations and subsequent drillout.

MicroSeal^™ is a low-viscosity fluid system that self-diverts into leakage pathways to repair existing barriers. MicroSeal^™ can be injected into channels, micro-annuli, and pinholes where it forms a gas-tight seal while leaving the wellbore full drift, thus reducing risk and making it the most effective and economic solution on the market.

3x More Successful than Resins

 

 

 

 

C). NanoSeal^™

In applications where cement bond is good and injection cannot be established but small leaks exist/persist options are limited to extensive remediations to establish a new barrier entirely or intrusive treatments that mechanically alter existing cement. Both fail to address the root cause while incurring significant costs and risks.

NanoSeal^™ is a low-viscosity fluid system composed of sub-micron particles that penetrates deep into the smallest aperture gaps to eliminate fluid/gas migration. NanoSeal^™ is safe for application in environmentally sensitive applications, capable of penetrating 1,000s of ft, and strengthens the materials its injected into making it the only solution for healing defects in otherwise competent cement.
