PROPRIETARY DECISION TOOLS
How mid-sized operators recover lost production without full CAPEX replacement
Three purpose-built processes give you a defensible, engineered path to more uptime and production — without defaulting to a full system replacement.
Map My Compression Decision →
Operators facing compression problems are usually pushed toward one of two extremes: live with the failures, or replace the whole train. Both are expensive — one in lost production, the other in unnecessary CAPEX.
ETA's three proprietary tools exist for the decisions in between: which concept to select, why an existing system is underperforming, and how to extend or modify what you already have before you replace it.
01
DECIDE
USE IT WHEN
You're developing a field or facing declining pressure, and need to select a compression concept before committing capital.
CONCEPTCOMPRESSOR™
THE PROBLEM IT SOLVES
Choosing the wrong compression concept at the field-development stage is a decision that's costly and often irreversible once construction begins.
WHAT IT DE-RISKS
Over-specifying (paying for capacity or complexity you don't need) or under-specifying (a system that can't hold plateau production).

5Development Roadmap
PROOF POINT
Rosneft, Rospan asset
ETA rebuilt an inaccurate integrated asset model and cut simulation cycle time from a week to under four hours — turning a blocked field-development decision into one the client could act on.
02
DIAGNOSE
USE IT WHEN
Your existing compression system has chronic reliability issues, unplanned shutdowns, or a pattern of interventions that never quite fix the underlying problem.
CompressorDoc™
THE PROBLEM IT SOLVES
Repeated equipment failures that erode uptime, revenue, and stakeholder confidence — without a clear root cause.
WHAT IT DE-RISKS
Spending on the wrong fix (or the same fix repeatedly) because the root cause was never properly isolated from symptoms.

5Uptime Roadmap
PROOF POINT
BP, North Sea Andrew platform
An existing reliability issue combined with a planned satellite tie-in required a full reassessment of the compression train's fitness for purpose — reliability was restored ahead of schedule.
03
EXTEND
USE IT WHEN
Your facility is bottlenecked or your field's duty has changed, and a full system replacement isn't justified by the problem.
modgas™
THE PROBLEM IT SOLVES
Facilities outgrowing their original design basis, where the cost-effective answer is modification, not replacement.
WHAT IT DE-RISKS
Committing to a full rebuild when a targeted redesign would meet the same production objective at a fraction of the cost and downtime.

PROOF POINT
Pluspetrol, Cashiriari field, Peru
Declining reservoir pressure required a third compression train delivered in a remote, biodiversity-sensitive site with complex multiphase flow — delivered on programme and within budget.
