Everyone wants the flexibility to do what they want when they want. And yet operators today face significant challenges, such as installing clads below already installed clads, the accompanying ID restrictions, and the inability to isolate well zones or fix leaks fur-ther down the well. The result is that operators have to produce from the ‘bottom up’ of the well with severe limitations on well zone isolation.
The Meta Internal Clad? solution addresses these issues while enhancing well productivi-ty through the world’s first rig-less ‘clad through clad’ system. Field proven, the Meta In-ternal Clad, has allowed identical clads to be installed below already installed clads with no significant ID reductions, reinstating well integrity and therefore enabling production to be brought back to full capacity.
Effective in highly challenging well environments with tool flexibility allowing the inter-nal clad to pass through highly deviated sections of a well, the ability to isolate selected zones without significant ID restrictions brings an end to the limitations of ‘bottom-up’ production and means that operators maintain well access for future interventions.
And the result? Increased well integrity and optimised productivity for operators and the luxury of producing where you want, when you want. They say good things come to those who wait…why wait?
Increased production back to full production: 100%
Clad through clad: 0 restriction
Compromise: Zero
Application:
?Integrity: The Meta Internal Clad? enables operators to rapidly reinstate well integrity when challenges occur. Whether it is seal perforations, leaking connections, corroded casing, the shutting off of zones due to water breakthrough, the Internal Clad creates ro-bust gas tight connections with compliant metal contact across the length of the clad, which reinstates well integrity and optimises production
?Clad–Minimal Loss of ID: The Meta Internal Clad? is a genuine industry first. No one has previously managed to run a new clad system of the same size through the ID of an already set internal clad, with minimal loss of original casing ID. With consecutive clads of the same ID being set, the result is increased productivity and recovery from all pro-ducing zones, the isolation of producing formations when watered out, full access for fu-ture interventions and the ability to turn the ‘bottom-up’ production approach on its head.
?Perforation Isolation: The Meta Internal Clad? optimises production due to its ability to quickly and easily isolate perforations which are no longer beneficial, without significant restrictions in ID and therefore maintaining well access for future intervention.
Case study
Challenge
Our Far East client’s business model was to perforate and produce key zones of a well first then produce the rest over time.
Prior to using Meta’s technology, our client, like most operators across the globe, did not have the freedom to produce its wells in the optimum way.
Previous technology allowed the client to produce the key zone, but following water in-gress and subsequent zonal isolation, the technology’s ID restricting nature would not al-low lower zones to be produced. Or it would limit any re-perforation and / or well inter-vention.
Requirement
–Clad through clad capability
–Wireline deployment
–2000 psi external seal pressure rating
–Life of well solution
This method did not capitalise on the production of the well and therefore did not maxim-ise profitability.
The client wanted a clad solution, which would give them the freedom to produce key are-as first, and then have the ability to perforate or carry out further well interventions in the lower formations in the well, without restricting their options. Also due to rig constraints it was essential that this be deployed via wireline.
Solution
The Meta Internal Clad, with its clad through clad capability, is a system that can be de-ployed on wireline and allow operators to set a clad below a previously installed Meta In-ternal Clad with no ID restrictions.
Demonstrating the Internal Clad’s unique clad through clad capability and minimal re-striction in ID, Meta then ran a further clad through the existing clad allowing production from zones lower in the well. Future well production is not comprised.
Results
Meta successfully ran and set a clad in the well and isolated perforations at a depth of 3250m and a temperature 120°, bringing gas production back to full capacity – an increase from 0.3 MMSCF to 2.0 MMSCF/
About the company
Meta is a premium downhole isolation company offering complete integrity across the life of the well from well architecture and drilling through to completion, production and decomissioning. With its unique patented Metalmorphology technology, Meta’s products shape metal downhole to create gas-tight, axial load bearing, metal-to-metal downhole isolation for the life of the well. The result for operators is reduced risk, the protection and maximisation of future production, and prof-itable and productive wells.
