The science platform

Materials science,
practised as engineering.

BETOSIM™ is not a product line with a laboratory attached. It is a formulation platform, a design method and a data discipline — and every system that leaves it carries the evidence of all three.

Engineered cementitious materials

The binder is a designed system,
not a bag of powder.

Conventional oilfield cement is a commodity: a class of Portland cement, a handful of additives and a pump schedule. It performs adequately in the wells it was designed for — and it is the single most common origin of loss of well integrity in the wells it was not.

BETOSIM systems are engineered cementitious materials. The binder chemistry, the particle-size distribution, the reinforcing and healing phases and the fluid-loss behaviour are treated as design variables, tuned against a defined failure mode rather than a generic specification. The result behaves less like cement and more like a purpose-built structural material that happens to be pumpable.

What we design against

  • Mechanical failure — radial cracking and de-bonding under pressure and temperature cycling, addressed through elasto-plastic behaviour rather than raw compressive strength.
  • Placement failure — losses into weak or depleted formations, addressed by reaching structural performance at densities conventional slurries cannot achieve.
  • Time — micro-annuli and micro-fractures that open years after the job, addressed by autonomous healing chemistry designed to close them as they form.
  • Chemical attack — carbonic-acid and thermal-cycling environments, designed for over regulatory rather than commercial timescales.

The same platform produces our strategic concretes. A material engineered to hold a 3,000-metre annulus and one engineered to hold a long-span structure are, in laboratory terms, the same discipline pointed at a different load case.

Per-well engineering workflow

Well file in.
Validated system out.

There is no BETOSIM catalogue number that fits your well. There is a workflow that produces the system your well needs, and a test record that proves it before it is pumped.

01 — WELL FILE IN

Analyse

Formation strength and lithology, thermal regime, pressure and injection cycling, offset well history, prior integrity failures, regulatory barrier requirements.

02 — ENGINEERED DESIGN

Formulate

A candidate system is drawn from the formulation library and tuned — density, elasticity, healing capacity, thickening time and fluid loss set against the identified failure mode.

03 — VALIDATED SYSTEM OUT

Prove

Validated to API Spec 10A / RP 10B-2 protocols, witnessed by the client’s engineers where required, and released with the worksheets that support every number on the sheet.

Inputs we ask for
Well schematic and casing programme, formation and pore-pressure data, bottom-hole static and circulating temperatures, mud and spacer programme, integrity history and the barrier requirement you must satisfy.
What is returned
A well-specific system design, the laboratory programme that validates it, the pumping envelope and the QC plan for execution — with the test worksheets behind every figure.
Standards framework
Slurry design and testing follow API Spec 10A and API RP 10B-2 protocols. Mechanical and durability characterisation is run to the recognised standard applicable to the property under test.
Turnaround
Set case by case against the laboratory programme the design requires. We do not quote a turnaround before we have seen the well file.
The formulation library

Every system we have ever
validated, kept as data.

The library is the asset. Each validated formulation is held with its full test record — composition, conditions, apparatus, operator, date and result — so that a design produced today can be traced to the evidence that justified it, and reproduced years later in a different laboratory on a different continent.

This is what makes the technology licensable. A licensee does not receive a recipe; they receive a family of validated formulations, the method that selects between them and the data discipline that keeps the result defensible in front of an operator’s engineers, an auditor or a regulator.

Data discipline

  • Traceability — every published figure resolves to a specific worksheet, apparatus and date.
  • Reproducibility — formulations are specified so that a qualified laboratory can repeat the result, not approximate it.
  • Version control — formulation families are versioned; superseded versions stay in the record rather than disappearing from it.
  • Claims control — no performance figure enters commercial use until the record behind it is complete. This governs us and, by licence, every licensee.
Validation posture

Where our numbers come from —
and where they are going.

We would rather explain the status of our evidence than overstate it. Our published headline figures come from the group’s own validation programme. Independent re-verification is under way, and we say so plainly until it is complete.

R&D and accreditation

The UK ISO 17025
accreditation programme.

BETOSIM Ltd is building its United Kingdom testing and verification capability around accreditation to ISO/IEC 17025, the international standard for the competence of testing laboratories. That programme is in progress; we are not yet accredited, and we do not describe ourselves as accredited.

Until it completes, independent verification is obtained through recognised accredited laboratories, and our own results are published as what they are: results from the group’s validation programme, with the worksheets available for inspection under NDA.

Why we are doing it the slow way

Our licensees will sell into markets where a performance claim is a contractual and sometimes regulatory undertaking. An accredited chain of evidence is not a marketing asset — it is what makes the claim survivable when an operator’s technical authority, an insurer or a regulator asks the obvious question. Compliance is the moat.

Research direction

  • Long-duration durability characterisation of healing systems under representative downhole conditions.
  • Barrier performance in CO2-rich environments over regulatory timescales.
  • Thermal-cycle endurance for geothermal completions.
  • Binder-intensity reduction at constant structural performance across the concrete lines.

We engage the United Kingdom research ecosystem — universities and accredited laboratories — as the environment in which this work is done and checked. More about the company →
