Typical payback window on Sigma4 fees through delivered operational gains

Experience in finding efficiencies during historic price lows

Combined founder experience in UKCS operational engineering

Sigma4 exists to protect and improve asset value.

In mature North Sea operations, small performance gaps quickly become material. We bring experience and innovation to help teams close performance gaps and deliver measurable improvement.

100% focused on UK oil and gas. No diversification. No distraction.

Most of our potential competition is scrambling to show renewables revenue as part of an exit strategy. We aren't. We plan to be operating in oil and gas 50 years from now.

Steve co-founded Performance Improvements Group in 1997. Within a decade, operators across the UKCS were calling it "the AA of the North Sea": the team you called when the asset was struggling and you needed it fixed, not advised on.

PI survived its first year through an oil price crash below $10/bbl. It grew to over 120 people before acquisition by AMEC in 2009, having worked for most of the majors and independents across the UKCS.

With hands-on experience gained from working offshore on over 50 assets over a 40 year career to date, Steve is equally at home in the board room as a control room, championing operational excellence and continuous improvement to deliver bottom line value to clients.

Fraser has worked on both sides of the operator–contractor relationship, from the process deck of North Sea FPSOs to leading large-scale EPC programmes and emissions reduction strategies internationally.

Fifteen years of that gives you an unusually complete picture of where technical efficiency is lost and why.

As a Chartered Chemical Engineer, Fraser brings the engineering rigour that makes PACE recommendations defensible at board level. As someone who has managed those same operations from the operator side, he understands the constraints that make most external advice difficult to implement.

We're hiring experienced senior engineers and AI-savvy junior engineers across all four PACE pillars. Steady growth, no churn, positive culture. That's how we’re planning to build Sigma4.

COO & Operations Director

You're making portfolio-level decisions about assets aging faster than your budget allows. Which get investment, which approach CoP, which can be pushed harder without compromising integrity.

You need an independent view you can trust, one not shaped by a consultant's interest in extending their own engagement. Sigma4 provides the technical and commercial analysis that makes those decisions defensible at board level, with a contract model that keeps our incentives aligned with yours all the way to CoP.

Asset Manager

You own the production number, the safety case, and the budget, usually simultaneously. When the regulator asks a question, you need a clear answer. When production drops, you need a root cause, not a hypothesis. When a TAR runs long, you carry the consequences.

Sigma4 provides the embedded expert resource that gives your team the depth it needs when it's stretched. We work alongside your people, not around them.

Technical Lead & Specialist Engineer

Sometimes you need someone who has been where you are. OEM-level knowledge your in-house team can't carry. An independent read on a problem you've been too close to for too long. SIL verification that will withstand regulatory scrutiny.

We go offshore. We solve it. On the asset, not in a report.

01

Understand before we scope

We don't write a proposal until we have properly understood the problem. That means time at the proposal stage with your commercial drivers, your operational constraints, your in-house team dynamics, and the risks you're managing. Most consultancies skip this. We don't.

02

See the complete PACE picture

Every engagement is assessed across all four PACE pillars, because the levers interact. A recommendation that is technically correct but economically incoherent isn't a recommendation worth having.

03

Deliver early wins on purpose

The fastest way to build trust with a new client team is to solve something visible, quickly. We identify and deliver quick wins early, with your team, so every win is owned collectively. Our job is to make you and your team look good. Not to be the heroes.

04

Embed, monitor and sustain

Real-time KPI dashboards, leading indicators, embedded expert support. Improvements that aren't monitored don't last. We stay long enough to see sustained improvement, not just initial gains.

05

COMMITTED TO THE END GAME

Same team, same asset, same accountability, measured all the way to CoP. Asset knowledge compounds year on year, not on every fresh engagement. Embedded expertise is the point; the commercial wrapper around it is a conversation for when you're ready.

Partnership

We work in collaboration to achieve a win-win and share lessons learned. Our job is not to be heroes but to make our clients heroes, they'll remember who made the difference.

Positivity

We approach work with energy, enthusiasm, optimism and confidence. We are radiators, not sinks. Clients have enough issues to deal with; if we can lift the mood in the room, they'll want us back.

Proactivity

We think several moves ahead to anticipate and solve risks before they become issues. Unless checked, risks become incidents, losses, emissions and cost. Not on our shift.

Performance

We consistently deliver, higher safety, more production, lower emissions, reduced costs, on budget and on time. Consistent on-time delivery of added value is how a reputation is built.
