Nigeria & West Africa
Engineering-led. Operator-focused. Built for Africa.
Who We Are
Harrowgate Energy Services is a wholly indigenous Nigerian integrated energy services firm.
We work with operators across the upstream oil and gas sector in Nigeria and West Africa — providing multidisciplinary engineering, project delivery, and technical advisory.
Our team brings international experience across Shell E&P deepwater programme management, Siemens Energy automation and controls, Colonial Pipeline brownfield integrity, and large-scale greenfield industrial delivery — placed entirely at the service of our clients.
Whether the challenge is a new facility from concept, a capacity upgrade, a field development plan for a new licence, or the engineering support your team simply needs to move forward — we are here to help you solve it.
Our Commitments
We recruit and retain engineers with the right qualifications and attitude — people who continuously add value. Our team is our product.
We work alongside your team — bringing international methodology to Nigerian operating realities and producing results that exceed the sum of their parts.
Whatever the complexity, we focus on delivering appropriate, cost-effective solutions — within budget, in compliance with industry standards, and tailored uniquely to you.

Hydraulic modelling, integrity assessment, cathodic protection, pigging systems
Wellhead pads, flow station steel, manifold foundations, tankage
Well programmes, casing design, completions, wellhead selection, well integrity
Artificial lift, ESP/gas lift, flow assurance, sand management, optimisation
SCADA, DCS, PLC/HMI, SIL assessment, instrumentation-as-a-service
HV/LV distribution, generator tie-in, arc flash, area classification
Site development, access roads, foundations, drainage, camp infrastructure
HAZOP/HAZID, SIL, PSM, PIA compliance, safety case development
PMO build, stage-gate governance, contractor management, NCDMB compliance
RBL structuring, DFI advisory, capital structure, bankability assessment
What We Bring To You
Our Shell E&P background in deepwater and pipeline programme management means we bring the same governance standards, stage-gate discipline, and contractor management approach that major international operators expect of themselves.
Our Siemens Energy experience in turbine controls, SCADA systems, HAZOP/HAZID, and SIL studies across multiple countries gives our clients access to automation capability that is rarely available from a local Nigerian firm.
Our experience in PSM-aligned brownfield integrity management — from Colonial Pipeline and Stepan Company — gives us a genuine understanding of what aging infrastructure needs to remain safe, compliant, and productive.
Our experience governing large greenfield industrial programmes gives us a deep appreciation for the rigour, patience, and stakeholder alignment that complex capital projects require.
Our Journey
Growing with our clients across West Africa
Reactivate and strengthen our presence in the Nigerian market. Launch the HEEP programme. Build trusted engineering partnerships with marginal field operators and new PPL holders.
