RML-2.0 Surface Casing Patch

Customer needs a result! Revelation Management is pleased to introduce the renewed RML-2.0 Surface Casing Patch.

It was specifically designed for sealing shallow casing failures. Its unique design provides a large internal diameter for downhole access.

100% Success Rate

Proven in 270+ wells with no equipment failure

No Excavation

Eliminates digging out the wellhead to treat the failure

5.5–6 Hours

Predictable installation, far less than cementing

The RML-2.0 Surface Casing Patch Is

  1. More cost-effective than cementing operations.
  2. Eliminates the need to treat the casing failure by excavating the wellhead.
  3. Demonstrating a 100% success rate.
  4. Ensuring long-term sealing reliability beyond what cementing can achieve.

RML-2.0 Surface Casing Patch Advantages

  • Predictable installation time. The Casing Patch installation takes 5.5–6 hours, which is less time than cementing technologies or repairs that require digging out the wellhead.
  • Long-term isolation. Our mechanical sealing system delivers consistent, controlled setting and ensures long-term, dependable isolation for the full service life of the well.
  • Cost-effective retrieval. Can be removed from the well with minimal cost when required using standard fishing equipment.
  • Eliminates auxiliary risks. Unlike competing technologies, it does not require:
    • A bridge plug (which later needs milling out)
    • Corrugated pipe (which has low collapse resistance)
    • Cone-expanded end fittings (which may fail to provide full casing contact or can get stuck during installation)
    • Inflatable packers for pressure testing

RML-2.0 Surface Casing Patch Technical Features

  • Utilizes only a hydraulic setting tool to set the elements. No mechanical manipulation required for setting the elements.
  • By design, the Surface Casing Patch elements cannot be accidentally set under any circumstances.
  • Tested to 22.2 daN (50,000 lb) downward force with zero force applied to the elements.
  • ID of 108.61 mm (4.275”) on the 127 mm x 168.3 mm (5” x 6 5/8”) Surface Casing Patch.
  • Half-muled and beveled lower entry guide.
  • Allows the client to maintain well control via pumping of fluids down the annulus during RIH and setting of the Casing Patch.

About the Pressure Test Cup

The Pressure Test Cup model was specifically designed to reduce manufacturing costs and eliminate the need for a bridge plug and inflatable packers. Our equipment alone is sufficient to carry out the pressure test.

Our Pressure Test Cup model does not require running an additional hydraulic setting tool to bring it into the operating position.

At the same time, this model has limitations — a limited run-in depth, as it is suitable only for shallow applications.

What Can the RML-2.0 Surface Casing Patch Do for You?

Benefits
  • Can be removed from the well with minimal cost when required using standard fishing equipment.
  • Predictable installation time. The Casing Patch installation takes 5.5–6 hours, which is less time than cementing technologies or repairs that require digging out the wellhead.
  • Long-term isolation. Eliminates the risks of re-cementing operations. Our mechanical sealing system delivers consistent, controlled setting and ensures long-term, dependable isolation for the full service life of the well.
  • Well control via pumping of fluids down the annulus during RIH and setting of the Casing Patch.
  • Increased safety to personnel.
  • Reduces costs and minimizes production downtime. Eliminates costly cementing technology repairs.
  • With 6+ years of installation, durability and success, the element design has been proven in 270+ wells with no equipment failure.

RML Patch Slip Assembly — What We Do Better Than Our Competitors

  1. Coarser teeth (10 vs 13): allows more area for debris, helping prevent debris from packing in and compromising the function of the teeth.
  2. 3 slips (vs 4 slips): the slip area is the same, while delivering better centralization within the casing and better contact points if the casing is not perfectly round (elliptical or egged).
  3. Extra grooves and serrations: 2 of the 3 slips in the RML-2.0 patch slip-cage have extra grooves and serrations milled into them. This makes the slip more aggressive in biting into the casing and also allows extra room for debris, so it does not interfere with the contact point of the teeth within the casing.
