RML-LSA-3.0 Casing Patch: Advanced Large Sub Assembly
Revelation Management LTD (RML) and KhalidX Energy are pleased to introduce the next-generation RML-LSA-3.0 Casing Patch. Engineered with a large internal diameter (Large Sub Assembly) for unobstructed downhole access, this advanced technology delivers superior sealing reliability and operational efficiency far exceeding conventional cementing practices.
Cost-Effective
Significantly lower cost than repetitive cementing operations
High Success Rate
Proven in 270+ wells across 6+ years with 0% equipment failure
Long-Term Reliability
Permanent mechanical isolation matching full well service life
Strategic Partnership: RML & KhalidX Energy
Revelation Management LTD (RML), established in 2016 in Bonnyville, Alberta, Canada under Founder, President & CEO Don Slipchuk, provides premier downhole tools to major global operators including ExxonMobil and CNRL. KhalidX Energy is the exclusive Strategic Partner and representative for RML in Oman and across the Middle East.
Under this cooperation framework, RML leads technology development, engineering, and technical control, while KhalidX Energy oversees local representation, market access, and the establishment of a localized manufacturing and service facility in Oman.
Four-Stage Business Development Roadmap in Oman:
- Strategic Partner in Oman: Establish local framework with KhalidX Energy operating local facilities while RML directs technological development.
- Local Supply & Manufacturing: Procure standard tubulars, crossover subs, and components with gradual transfer of production to Oman.
- Talent Development: Recruit and train specialized Omani engineers and technical crews in advanced intervention tools.
- Regional Platform: Transform Oman into the regional hub for local content, service execution, and technology deployment across MENA.
Product Specifications & Materials
- Multiple Sizes: 5” to 7” (127.0 mm to 177.8 mm).
- Pressure Rating: Elements tested to a pressure of 3,150 psi (21.7 MPa).
- Thermal Rating: Can be dressed for an element rating of 343°C (650°F) for thermal applications.
- Tailored Element Stack: Customized based on exact wellbore parameters (Temperature, Pressure, H2S/CO2 gas composition).
- Product Composition:
- AISI 4130 HTSR / L-80 (80 KSI Min Yield)
- AISI 4140 HTSR / P-110 (110 KSI Min Yield)
- AISI 1018 Mild Steel (50 KSI Min Yield)
- AISI 1026 Mild Steel (50 KSI Min Yield)
RML-LSA-3.0 Advantages & Technical Superiority
- Predictable Installation Time: Executed in 2 runs (Dummy Run & Patch Run), taking substantially less time than multi-stage cement squeezes.
- Permanent Mechanical Isolation: Eliminates the risks and uncertainties of re-cementing operations.
- Cost-Effective Retrievability: Can be completely removed from the well at minimal expense using standard fishing tools.
- Eliminates Auxiliary Risks: Unlike competing systems, RML-3.0 does not require:
- A bridge plug (which later requires costly milling out)
- Corrugated pipe (which suffers from low collapse resistance)
- Cone-expanded end fittings (which risk incomplete contact or getting stuck during installation)
- Inflatable packers for pressure testing
- Hydraulic Setting Precision: Sets solely via hydraulic setting tool—no mechanical manipulation or rotation required.
- Zero Accidental Setting: Impossible to accidentally set the elements during run-in-hole (tested to 50,000 lb / 22.2 daN downward force with zero element load).
- Large Internal Drift: ID of 108.61 mm (4.275”) on the 127 mm x 168.3 mm (5” x 6 5/8”) patch.
- Half-Muled & Beveled Entry Guide: Ensures smooth re-entry and tool passage.
- Active Well Control: Allows the operator to maintain well control by pumping fluids down the annulus during RIH and setting.
Advanced RML-3.0 Patch Slip Assembly vs Competitors
- Coarser Teeth (10 vs 13): Provides larger clearance area for debris, preventing swarf and scale from compromising tooth engagement.
- Optimized 3-Slip Geometry (vs 4 slips): Equal total slip area while delivering superior centralization and optimum contact points in out-of-round, oval, or egged casing.
- Dual Aggressive Milled Grooves: 2 of the 3 slips feature extra milled relief grooves and serrations for deeper bite into high-grade casing and additional debris evacuation.
- Engineered Maximum Casing Contact: Designed and verified for full 360-degree contact force distribution against casing walls when set.
- Superior High-Strength Spring Arms: Heavy-duty spring arm architecture ensures that upon cone disengagement, slips return cleanly and stay flush to the mandrel, completely eliminating casing contact during retrieval.
- Shear-Screw-Free Neutral Release: Slips easily disengage into a neutral position upon pulling without resisting upward retrieval force, unlike competing systems with shear screws.
