The lowest-carbon remedial job is the one that was never required. We publish mechanisms, not slogans — and we do not claim a benefit we cannot trace to a physical cause.
Cement and concrete carry a genuine and well-documented carbon burden. Any materials company claiming to have solved that in a brochure should be read with care, and we would rather be read carefully than believed quickly.
So, plainly: we do not describe our products as green, carbon-neutral or sustainable. We do not publish a percentage reduction without saying what it was measured against. We do not count avoided emissions from work that has not been done. And we do not present a laboratory result as a lifecycle assessment.
What we do claim is narrower and, we think, more useful: materials that last longer and fail less produce less carbon over the life of the asset, through mechanisms that can be named, argued and checked. Those mechanisms are set out below.
A remedial cementing job is not a small event. It is rig or intervention-unit time, fuel, personnel movements, additional cement and steel, and deferred production — frequently followed by another attempt.
Systems engineered against the actual failure mode — elasto-plastic behaviour where the well cycles, healing chemistry where micro-fractures open — reduce the probability of that cycle beginning. Every avoided repair is avoided cement, steel, fuel and rig days.
The saving depends on the failure probability of the alternative in that specific well. It is calculable per well with the operator’s own data; it is not a number we can publish as a general claim, so we do not.
Most embodied carbon in a well or a structure is spent at construction. Amortised over sixty years it is modest; amortised over twenty because the asset had to be rebuilt, it is not.
A dense, low-permeability matrix resists the ingress that drives deterioration, and an elastic sheath survives the cycling that cracks a brittle one. Assets reach their design life instead of being rebuilt inside it.
Durability claims over decades rest on accelerated testing and on materials science, not on sixty years of observation. We describe the evidence as what it is, and the long-duration programmes as under way.
Clinker production is where the emissions of a cementitious material overwhelmingly sit. The meaningful question is not how much binder is in a cubic metre, but how much binder is required to deliver a given structural capability.
Ultra-lightweight and fibre-engineered systems deliver structural performance at lower mass and permit thinner sections and lighter reinforcement — less material placed, and less binder per unit of capability delivered.
This is a functional-unit argument. Compared per cubic metre, a high-performance material can carry more binder, not less. We state the comparison we are making, because the comparison is the whole claim.
Carbon storage only counts while the CO2 stays where it was put. The cement sheath and the abandonment plug are the barrier that decides this, and they must hold on regulatory rather than commercial timescales.
Barrier systems engineered for CO2-rich environments make the containment side of carbon storage more defensible — which is the largest environmental contribution this technology can make.
Our CCUS work is a stated development direction, not a released product. We will describe it as available when the validation record supports it, and not before. See the roadmap →
As the United Kingdom company builds its testing and verification capability, environmental data is being put on the same footing as performance data: traceable to a method, attributable to a functional unit, and open to inspection.
Until that work is complete, this page carries no numbers. That is deliberate. An unverified environmental figure is worth less than no figure at all — and costs more when someone checks it.
Our validation programme, methods and data discipline are available for technical review under NDA, including by environmental and technical advisers.
