Integrated Asset Modelling

See the whole production system before making the compression decision.

Integrate reservoir, well, gathering network, process and compressor behaviour to determine where production is constrained, when compression is required and which field-development option creates the strongest life-of-field outcome.

Why Integrated Asset Modelling

A compressor cannot be optimised in isolation from the asset it serves.

Reservoir decline, well deliverability, gathering-system hydraulics, separator pressures, pipeline backpressure, process constraints and compressor operating envelopes all interact. Analysing one element in isolation can produce a technically sound answer to the wrong problem.

Declining field pressure Understand how falling reservoir and wellhead pressures affect future compression duty.
Uncertain compression timing Determine when compression begins to create material production value.
Network and process constraints Separate compressor limitations from upstream, downstream and facility bottlenecks.
Competing field-development options Compare location, capacity, staging and phasing using a common production basis.

The production system is connected

ETA links the elements that influence production so the compression decision reflects the behaviour of the whole asset.

What You Get

Engineering evidence for the next investment decision.

01

Life-of-field production forecast

Understand how candidate compression strategies influence future production performance.

02

Compression duty definition

Define flow, suction and discharge pressures, power and operating envelope as conditions evolve.

03

Constraint identification

Quantify where production is limited and distinguish compressor constraints from system constraints.

04

Option comparison

Compare central, field, wellhead or staged compression concepts on a consistent basis.

05

Phasing strategy

Identify triggers for additional trains, rewheels, modifications or new pressure stages.

06

Decision-ready recommendation

Translate modelling results into a practical recommendation for concept selection or FID.

How ETA Uses IAM

From integrated model to compression strategy.

The model is not the end product. Its purpose is to support a better engineering and investment decision.

Step 1

Define the decision

Clarify the production problem, decision criteria, field horizon and commercial question.

Step 2

Build / validate the model

Integrate reservoir, wells, gathering network, process facilities and compressor behaviour.

Step 3

Benchmark the base case

Establish current and future constraints before testing new equipment or modifications.

Step 4

Test development options

Evaluate compression location, timing, capacity, configuration and operating strategy.

Step 5

Translate to a roadmap

Recommend the preferred strategy, decision triggers, risks and next engineering actions.

When to Use IAM

Best suited to decisions where compression and production interact.

Field-development planning

Assess future compression requirements before selecting or revising a development concept.

Post-plateau decline

Determine how compression can sustain production as pressure and well deliverability decline.

Brownfield debottlenecking

Test whether the real constraint lies in wells, flowlines, facilities, compressors or export systems.

Compression concept selection

Provide system-level evidence for CONCEPTCOMPRESSOR™ option screening and selection.

Concept revalidation

Update the basis when pressures, reserves, forecasts or operating assumptions have changed.

CAPEX justification

Connect a compression investment to production recovery, timing and field-life value.

How IAM Fits Within ETA

A specialist capability supporting multiple ETA decisions.

IAM should be positioned as a technical capability beneath the relevant service or Decision Tool—not as a standalone software exercise.

CONCEPTCOMPRESSOR™

Uses IAM to support compression concept selection, timing, capacity and life-of-field strategy.

modgas™

Uses integrated analysis to locate production constraints and test brownfield redesign options.

CompressorDoc™

Provides wider system context where compressor performance or reliability problems may have external causes.
