Well Testing

“Reliable reservoir data for confident decisions”

Overview

At Omasup Energy Services, we deliver advanced well testing solutions that provide reliable reservoir data for confident exploration, development, and production decisions. Our services help operators fully understand reservoir performance, fluid behavior, and well integrity.

Well testing delivers critical insights into reservoir productivity and deliverability, accurate fluid characterization of oil, gas, and water, precise determination of reservoir pressure and boundaries, and verification of well integrity and completion effectiveness for safe and optimized operations.

Our Well Testing Solutions

01

Drill Stem Testing (DST)

Real-time reservoir evaluation during drilling, delivering accurate pressure and flow data without full completion to confirm productivity and reservoir boundaries.

02

Surface Well Testing (SWT)

Precise surface measurement of flow rates, pressure, and fluid properties using portable systems and advanced multiphase metering for onshore, offshore, and deepwater operations.

03

Reservoir Characterization

Integrated analysis of downhole and surface data to support dynamic reservoir modeling and long-term production planning.

Where Well Testing Applies

  • Exploration & appraisal wells — Confirm productivity and reservoir boundaries early.

  • Reservoir modeling & characterization — Feed dynamic models with reliable downhole and surface data.

  • Production optimization — Applied in both conventional and unconventional developments.

Key Benefits

  • Accurate reservoir evaluation
  • Reduced uncertainty in field development
  • Optimized production performance
  • Enhanced safety and well integrity
  • Lower operational costs through reduced NPT
We combine engineering expertise, advanced technology, and dependable service delivery to provide precise well testing solutions for smarter, faster, and safer decisions.
