Technical Expertise

Deep Capability Across Basins, Reservoir Types, and Asset Stages

Our team has worked across the full spectrum of subsurface challenges — from frontier exploration to mature field redevelopment — in basins spanning four continents.

Core Disciplines

Where Our Technical Depth Lies

Atria Energy's advisory capability spans the integrated subsurface workflow. Each discipline is led by a specialist with direct operator experience in that domain.

01

Structural & Stratigraphic Interpretation

Regional and prospect-scale interpretation of 2D and 3D seismic datasets. Fault framework analysis, horizon mapping, depth conversion, and structural uncertainty assessment. Extensive experience in extensional, compressional, and strike-slip tectonic settings.

02

Reservoir Geology & Sedimentology

Facies analysis, depositional system interpretation, and reservoir architecture modelling for clastic and carbonate reservoirs. Core description, thin section petrography, and diagenesis assessment integrated with log and seismic data.

03

Seismic Attribute Analysis & AVO

Advanced seismic attribute extraction and interpretation for reservoir characterisation and direct hydrocarbon indication. AVO analysis, inversion workflows, and spectral decomposition for stratigraphic and fluid prediction.

04

Dynamic Reservoir Simulation

Full-field and sector model construction, history matching, and production forecasting using industry-standard simulation platforms. Sensitivity analysis and uncertainty quantification to support development decision-making.

05

Formation Evaluation & Petrophysics

Comprehensive wireline log analysis, core calibration, and fluid characterisation. Net pay determination, saturation modelling, and petrophysical parameter derivation for volumetric and simulation inputs.

06

Unconventional Reservoir Evaluation

Shale gas, tight oil, and coalbed methane assessment including geomechanical analysis, completion design optimisation, and production forecasting. Experience across North American and emerging international unconventional plays.

Project Highlights

Representative Engagements

The following examples are illustrative of the type and scale of work Atria Energy delivers.

Field DevelopmentNorth Sea

Full-Field FDP for a Mid-Size Independent Operator

Led the integrated subsurface workstream for a full field development plan covering a 200 MMboe oil and gas accumulation. Delivered static model, dynamic simulation, well programme, and production forecast in support of FID. Project sanctioned on schedule.

Due DiligenceWest Africa

Pre-Acquisition Technical Due Diligence for a PE-Backed Buyer

Conducted independent technical due diligence on a deepwater asset package comprising three producing fields and two appraisal discoveries. Assessed reserves, production forecasts, and development upside. Findings directly informed bid pricing and risk allocation.

Production OptimisationSoutheast Asia

Production Optimisation Study for a Mature Gas Field

Integrated production analysis and reservoir surveillance study for a mature gas condensate field experiencing accelerating decline. Identified infill drilling targets and compression timing recommendations that extended plateau production by 18 months.

ExplorationEast Africa

Exploration Portfolio Screening for an NOC

Rapid technical screening and risking of a 12-block exploration portfolio for a national oil company preparing for a licensing round. Delivered prospect inventories, play fairway maps, and ranked opportunity set within a six-week turnaround.

Reserves CertificationNorth Africa

Competent Person Report for a Stock Exchange Listing

Prepared an SPE-PRMS compliant Competent Person Report covering proved, probable, and possible reserves across five fields in support of a Main Market listing. Report accepted by the exchange and published in the company prospectus.

AppraisalCaspian

Appraisal Well Planning for a Carbonate Discovery

Subsurface advisory for the planning of two appraisal wells on a significant carbonate discovery. Defined well objectives, target depths, and data acquisition programme. Both wells encountered reservoir as prognosed and materially upgraded the resource estimate.
