By combining our well test (pressure transient) and advanced decline (rate transient) analysis services, SAJ Energy Services provides a comprehensive understanding of reservoirs, completion efficiency, and optimization potential.


Well Testing (Pressure Transient Analysis)

Design and analysis of multi/single point flow and buildup for conventional and multi-fractured horizontal wells, injection and falloff (including mini-frac analysis), DST and perforation inflow tests

Determination of near wellbore reservoir parameters (permeability, skin, fracture parameters)

Estimation of reservoir pressure, distances to reservoir boundaries and/or heterogeneities

Prediction of deliverability potential at various flowing conditions

Recommend potential stimulation (for damaged wells) or optimization candidates (utilizing tubing performance curves and liquid lift calculations)




Rate Transient Analysis

Reservoir characterization (permeability, skin, fracture half-length)

Diagnose changing skin or permeability conditions

Monitor well performance in competitive drainage situations

Monitor productivity to ensure proper production allocation

Analytical and numerical production modeling – single zone vertical to multi-frac horizontal wells

Determination of stimulated reservoir volume, optimal well spacing and EUR/well for unconventional reservoirs
