Well Testing

Drill Stem Testing (DST) is a core discipline at Excelsior Energy, where we deliver end-to-end well testing solutions that span from detailed planning and field execution to high-quality data interpretation and reporting, all in accordance with international industry standards. Our expertise covers the full spectrum of DST services, including inflow and recovery testing with representative fluid sampling for advanced laboratory analysis. We conduct Injection Fall-Off Testing to evaluate tight formations and hydrocarbon suppression potential, as well as Diagnostic Fracture Injection Testing (DFIT) to assess caprock integrity and stress profiles—critical for horizontal drilling, fracture stimulation, and geotechnical studies. Additionally, our Air Assisted Flow Testing (AAFT) services enable extended-reach reservoir evaluations and efficient fluid recovery, particularly for water production wells, using downhole shut-in tools for precise control and accelerated testing cycles. Excelsior Energy’s DST capabilities provide clients with the data and insight required for confident reservoir evaluation, completion design, and development planning.
