Before committing capital to overhaul programs, parts purchases, or replacement decisions, oil and gas operators need an evidence-based picture of what they actually have on the ground. Reactive maintenance budgets are often built on assumption rather than measurement — and the cost of getting that picture wrong is measured in deferred barrels, emergency parts freight, and unplanned compressor train downtime.
Planterra Energy delivers independent, on-site technical assessments of existing CAT G3612, G3616, G3608, G3500-series, and related compression and power-generation infrastructure. The audit documents engine condition, total operating hours, top-end and in-frame component status, fuel-gas quality, lubricant trending, sour-gas exposure controls, and prioritized repair requirements — engine-by-engine, with as-found and as-left photographic evidence and a written report formatted for executive review and procurement decision-making.
Our lead technical specialist has personally conducted CAT G3600 and G3500 reliability assessments at PetroPiar, PetroBoscan, Boquerón, and Quiriquire — operating environments that span Eastern Venezuela's heavy-oil belt, the Maracaibo basin, and the sour-gas duty cycles that define Venezuelan compression operations. That field history is the difference between a generic engine inspection and an assessment grounded in how these specific engine populations behave under real Venezuelan operating conditions.
Cylinder condition, liner distress and bore wear, valve recession, deposits, blowby measurement, turbocharger and exhaust temperature balance, intake restriction, aftercooler performance, jacket-water control, crankcase pressure, and bearing risk indicators — captured with as-found / as-left documentation.
ADEM and ESS event review, misfire and detonation analysis, ignition timing, spark plug and coil condition, harness and grounding integrity, air-fuel ratio response, start reliability, and nuisance-trip diagnosis.
Gas chromatography review, methane number management, Wobbe index and BTU consistency, hydrogen sulfide (H₂S) and CO₂ content, water dew point, hydrocarbon liquids carryover, fuel pressure regulation, and derate exposure from variable associated gas.
Oil sample trend analysis (TBN, TAN, oxidation, nitration, wear-metal mapping, viscosity), sour-gas oil suitability and change-interval optimization, coolant chemistry, cavitation protection, scaling, and contamination.
Compressor unloader and valve health, alignment and coupling condition, vibration signatures, cylinder balance, AVR stability, protection-trip review, and production-deferment mapping at the train level.
H₂S work-permit discipline, fixed and personal detector coverage, rescue readiness, isolation and purge controls, and SCBA / supplied-air verification — calibrated to U.S. NIOSH exposure limits regardless of host-country variance.
Our lead technical specialist has conducted CAT G3600 and G3500 assessments and overhauls at the following Venezuelan operating environments:

Every Planterra Field Assessment & Audit engagement produces a defined deliverable set, written to the standard a U.S. shareholder, lender, or counterparty procurement organization expects to see:
Each deliverable is built to be acted on. The audit report is not the end product — the decisions it enables are.
Tell us what you’re looking to mobilize—and we’ll reply with next steps and a practical deployment path.
We operate in Venezuela under Big Oil standards—so you don’t build locally or manage ops on the ground.
