Subsurface Engineering, Reservoir Management and Advisory

We support opportunities from basin and acreage evaluation through appraisal, development planning, redevelopment and late life. 

Our capability includes seismic interpretation, petrophysics, geomodelling, static and dynamic simulation, volumetrics, reserves and resources assessment, well placement, uncertainty analysis, EOR and IOR evaluation and full-field development planning.

By bringing the relevant disciplines together around a specific decision, we help clients understand what the available data supports, where uncertainty remains and which technical work will add meaningful value.

Our production teams help clients understand well and field performance, identify production losses and manage opportunities through to implementation. 

Services include production and reservoir surveillance, forecasting, allocation and reporting, well-performance analysis, production optimisation, flow assurance, network modelling, artificial-lift evaluation and production technology.

Support can be provided for a focused performance challenge or as a continuous outsourced production and reservoir management service.

Geomechanical understanding can influence well design, production performance, field development, storage integrity and abandonment strategy. 

Our specialists undertake pore-pressure and fracture-gradient studies, wellbore-stability assessment, sand-production and sand-control studies, compaction and subsidence analysis, fault and fracture evaluation and crossflow assessment.

We also support core-programme design and management, specialist laboratory studies and the integration of core results into reservoir, completion and production decisions.

We combine technical understanding with commercial analysis to support transactions, investment decisions, reserves reporting and portfolio strategy. 

Our work includes acquisition and divestment due diligence, asset valuation, data-room evaluation, Competent Person’s Reports, reserves audits and certification support, unitisation and determination, portfolio analysis and post-acquisition transition.

Advice is developed around the decision and the applicable reporting framework, including SPE-PRMS and UNFC where required.

Our digital capability combines subsurface expertise with software developed around recurring reservoir and production workflows.

POSEIDON supports mature-field reservoir management and the identification of remaining-oil opportunities by bringing geological, reservoir and production information into a structured workflow.

TITAN provides a connected environment for daily production management, optimisation, forecasting and reporting, helping production teams identify performance gaps and focus engineering effort. We also develop and digitalise client-specific workflows where an established process can be made faster, more consistent or easier to repeat.
