Bore-hole Sealing Sleeve

Bore-hole Sealing Sleeve – High-Integrity, Corrosion-Resistant Sleeve for Zonal Isolation, Casing Protection, and Fluid Migration Control in Water Wells, Geothermal, and Oil & Gas Boreholes Across the GCC

In subsurface operations where fluid migration, casing corrosion, and formation cross-flow threaten well integrity and environmental safety, the Bore-hole Sealing Sleeve serves as a critical engineered barrier. Designed to be installed inside well casings or open boreholes, this robust sleeve isolates zones, protects base pipe from abrasive or corrosive fluids, and provides a reliable sealing surface for packers, inflatable plugs, or cement bonding in water supply wells, geothermal loops, monitoring boreholes, and oil & gas injection/abandonment operations across the UAE, Saudi Arabia, Oman, and beyond. At Qalalam Industrial Supply, our Bore-hole Sealing Sleeves are manufactured from high-grade stainless steel (316L, Duplex 2205), carbon steel with epoxy lining, or specialty alloys, engineered to withstand saline groundwater, high temperatures, abrasive sand, and chemical exposure in the harsh subsurface environments of the Middle East.

Unlike temporary plugs or standard casing patches, the Bore-hole Sealing Sleeve is a permanent or semi-permanent engineered solution that ensures long-term zonal isolation—critical for groundwater protection, reservoir management, and regulatory compliance in GCC regions where water scarcity and environmental regulations are stringent.

Core Functions: Sealing, Protection, and Isolation

The Bore-hole Sealing Sleeve performs three essential roles:

1. Zonal Isolation:
   Prevents vertical fluid movement between aquifers or formations—critical for drinking water safety and geothermal efficiency.
2. Casing Protection:
   Shields the original well casing from abrasion (sand), corrosion (chlorides, H₂S), and erosion (high-velocity flow).
3. Sealing Interface:
   Provides a smooth, compatible surface for packers, bridge plugs, or cement to achieve leak-tight isolation.

This makes it indispensable for well rehabilitation, abandonment, monitoring well construction, and geothermal loop integrity.

Design & Installation Features

• Diameter Range: 50mm to 300mm (2″ to 12″)
• Length: 1m to 6m standard (custom up to 12m)
• Wall Thickness: 3mm to 10mm (based on collapse pressure)
• End Connections:
  • Plain end (for welding or cementing)
  • Threaded (API LCSG) for mechanical joining
  • Flanged for surface installations
• Surface Finish:
  • Internal: Ra ≤ 1.6µm (for packer compatibility)
  • External: Coated or bare (per spec)

🔧 Pro Tip: For packer installations, specify internal diameter tolerance h9 and no weld seams in the sealing zone.

Frequently Asked Questions (FAQs)

Q1: Can I install a bore-hole sealing sleeve in an existing well?
A: Yes—via wireline, coiled tubing, or drilling rig. Sleeves can be:

• Cemented in place (most common)
• Mechanically expanded (for open hole)
• Packer-anchored (for temporary isolation)
  We provide installation engineering support for your method.

Q2: What’s the difference between a sealing sleeve and a casing liner?
A: A casing liner is structural—it carries load and replaces damaged casing. A sealing sleeve is non-structural—its primary role is isolation and protection. Liners are thicker (8–12mm); sleeves are thinner (3–8mm) and optimized for sealing.

Q3: Do your sleeves comply with UAE groundwater regulations?
A: Yes. Our SS 316L and Duplex 2205 sleeves meet:

• UAE MOCCAE environmental standards
• GCC Standardization Organization (GSO) requirements
• ISO 11960 for well tubulars
  We provide compliance documentation with every order.

Q4: Can you supply sleeves with pre-installed packer bores?
A: Yes. We machine precise internal diameters at specific depths for:

• Inflatable packers
• Mechanical bridge plugs
• Cement retainers
  Just provide your packer model and setting depth.

Q5: How do you prevent galvanic corrosion between sleeve and original casing?
A: We recommend:

• Insulating centralizers (non-metallic)
• Matching materials (e.g., SS sleeve in SS casing)
• Dielectric coatings on carbon steel casings
  Our engineers can model galvanic risk for your well.

Q6: What’s your lead time for custom-length sleeves?
A: 7–10 days from Dubai for standard materials. 12–15 days for Hastelloy or custom coatings. We keep 4″–8″ SS 316L in stock for emergency rehab.

Q7: Can sleeves be used in horizontal or deviated wells?
A: Yes—with centralizers to ensure even cement distribution. For high-angle wells (>60°), we recommend shorter sections (1–2m) for easier installation.
