Field Applications
| Primary Zonal Isolation |
Requirements:
- Reduce / eliminate fluid loss to the formation and/or damaging the formation
- Avoid flow paths in the annulus
- Achieve successful pressure tests that allow drilling to depth
- Comply with tighter regulatory requirements for additional annular barriers to optimize wellbore architecture integrity
- Withstand stress loads brought on by cyclic loading and/or annular deformation
- Resist failure and maintain isolation throughout the high pressures of completions operations and drawdown during production
- Prevent annular gas migration and/or water cut
- Contain unwanted flow
- Avoid environmental hazards and operational issues
How WellLock resin can address primary zonal isolation requirements:
- Highly elastic with compressive strengths proven up to 48,500 psi
- Can provide a gas impermeable seal to help preserve aquifers
- Can be pumped as a fluid stage in primary cementing operations

| Secondary Annular Barrier |
Requirements:
- Withstand increasingly higher concentrations of fracture placement
- Establish wellbore architecture able to tolerate stress loads brought on by cyclic loading and/or annular deformation throughout the high pressures of hydraulic fracturing
- Demonstrate sensitivities regarding environmental sustainability, particularly in reference to aquifers
- Work with suppliers that can help exceed the regulated wellbore architecture requirements and regulatory concerns
- Comply with tighter regulatory requirements for additional annular barriers to optimize wellbore architecture integrity
How WellLock resin can address secondary barrier requirements:
- Demonstrate elastic recovery via the infinite polymer network
- This can occur even under severe pressures (unconstrained compressive strength up to 48,500 psi in laboratory tests)
- Achieve a casing-to-casing gas-impermeable seal, a secondary barrier to the primary cement sheath
- As such, it is placed as a fluid stage during cementing operations – eliminating the need for set time of a casing packer
- Can provide an annular barricade capable of blocking any flow through the annulus that may develop over time, preventing flow beyond the point of where the resin is placed
- Flow prevention can be achieved by a high-pressure seal of 1,000 psi per foot.
- Be pumped as a fluid stage in primary cementing operations

| Remediation |
Requirements:
- Address water break through
- Seal micro-annuli
- Repair tight casing leaks
- Contain gas migration
- Fix damaged sand screens and gravel packs
How WellLock resin can address remediation requirements:
- Once an injection rate is established and it has been determined the area is viable to receive a fluid, this resin can be bullheaded down the annulus for a squeeze operation
- Zero yield point allows this resin to infiltrate very small openings and achieve depths of penetration not achievable by conventional cements
- Need for acid cleanup is not required, helping deliver operational time and cost savings
- An un-weighted resin can penetrate micro-pore spaces
- Like water, the starting force to achieve flow is very low
- Since fluids are present, it is a uniquely valuable property for this resin to withstand contamination by up to 30% and still form a competent bond with high compressive strengths
- This is due to a phenomenon known as “infinite polymer network” whereby this resin establishes covalent bonds throughout that require profoundly high pressures to break

| Plug & Abandon (P&A) |
Requirements: Achieving successful pressure tests of plugs across
- Hydrocarbon / producing zone(s)
- Casing shoe(s)
- Fresh-water aquifer(s)
- Additional strata if prescribed by the ruling regulatory authority for any given field globally
- Environmental sustainability
How WellLock resin can address P&A requirements:
- Superior mechanical bond for a permanently plugged well
- The resin can displace any aqueous or hydrocarbon based fluid without degrading the bonding strength or the ability to resist cracking
- Highly economical solution due to the conservative volume of WellLock resin required to establish a sustainable plug
- Since fluids are present, it is a uniquely valuable property for this resin to withstand contamination by up to 30% and still form a competent bond with high compressive strengths
- This is due to a phenomenon known as “infinite polymer network” whereby this resin establishes covalent bonds throughout that require profoundly high pressures to break

| Injection and Disposal Wells |
Injection and Chemical Disposal Well Challenge
- Demonstrate social responsibility by essentially making it impossible for any injected or disposed fluids to affect aquifers
- Adhere to regulatory injection and/or disposal well requirements
- Injection well: secure the fluid in the originating zone once re-injected
- Demonstrate a concern for environmental sustainability and protection of fresh-water aquifers, groundwater and surface resources
- Secure all levels of casing with a hydraulic seal
- Isolate the injection zone with a secondary barrier, typically a packer
- Protect tubing from corrosion and use corrosion resistant slurries for the hydraulic seal in the annular space
How WellLock resin can address injection and disposal well requirements:
- This resin is inert, and does not corrode or degrade when in contact with corrosive chemicals such as CO2 (carbon dioxide), NaCl (sodium chloride), carbonation, salt, etc.
- Superior mechanical bond for a permanently sealed well
- Since fluids are present, it is a uniquely valuable property for this resin to withstand contamination by up to 30% and still form a competent bond with high compressive strengths
- This is due to a phenomenon known as “infinite polymer network” whereby this resin establishes covalent bonds throughout that require profoundly high pressures to break
