Cost Efficiency
Cutting costs on a late-life asset is not always the right move.
Sometimes a targeted investment in reliability or chemical management extends the economic field life by months, and the NPV of those additional months exceeds any cost reduction achievable at the same margin. Sigma4 runs both sides of that calculation. Our cost work starts from benchmarking: what should this asset cost to run, relative to comparable UKCS assets at a similar stage? From there, we identify where spending is genuinely excessive, where it is insufficient, and what the economic consequence of each position is.

The view is commercial first, technical second. Every recommendation is presented in $/boe and CoP-shift terms, board-ready, scenario-modelled, independently scoped.
Opex benchmarking & cost reduction programme
Structured review against UKCS peer benchmarks, identifying top cost drivers, challenging value for money from major contracts, ranking reduction opportunities. We challenge whether opex is too low as much as too high: sometimes greater spend has a net economic benefit and pushes back the CoP date.
COO / Ops Director
C, $/boe reduction
P, economic life extended
E, efficiency savings
Contract & supply chain commercial review
Independent techno-economic review of major service contracts, integrated services, maintenance, inspection, logistics. KPI performance challenged, scope creep and commercial leakage identified, with the independent view needed to renegotiate from a position of knowledge.

C, leakage recovered
P, service performance ↑
Organisational review & resource optimisation
As companies merge and consolidate portfolios, we provide independent assessment of organisational design, competency gaps, offshore workforce optimisation and the correct balance of staff versus contracted resource. Especially relevant post-M&A or during late-life portfolio rationalisation.
COO / Ops Director
C, overhead optimised
A, competency gaps closed
Late-life economics & CoP timing assessment
Economic modelling of cessation of production timing under oil price, production decline and tax regime scenarios. Identifies optimal CoP windows, remaining investment requirements, value of life extension options and decommissioning cost benchmarking. Addresses the TCOP vs ECOP tension directly.

Project criticality & investment portfolio review
Independent review of a constrained project portfolio, identifying critical path activities, challenging prioritisation and providing a transparent methodology for ranking competing investments. Scarce resources (beds, cash, shutdown windows) allocated to the activities with the highest net benefit.

C, capital allocation
P, highest-value first

TAR planning, scope challenge & execution support
Independent expert support across the full TAR lifecycle, scope development and challenge through to onsite execution oversight. Safety-critical work correctly prioritised, beds optimised and opportunistic maintenance windows captured when unplanned events create access.

Cost cuts that defer safety-critical maintenance aren’t savings.
The right call sometimes is to spend more, not less — if it pushes CoP out and recovers more barrels. We bring the operational and economic discipline to make those judgements honestly, against UKCS peer benchmarks, not against the easiest line-item to cut.
