AGAT Laboratories’ Reservoir Engineering Division offers a complete range of services to efficiently explore, develop and produce petroleum resources. We offer clients one integrated source for complete formation and reservoir evaluation through a combination of professional personnel, advanced technology, experience and training. The Special Core, Detailed Reservoir Fluid and Scale and Corrosion services are designed to effectively resolve any of our clients’ problems in the areas of drilling, completion and production.

SPECIAL CORE ANALYSIS SERVICES are used for reservoir characterization, to allow better predictions of reservoir performance from core samples, and to evaluate any detrimental effects of subjecting a reservoir to foreign fluids, to avoid or eliminate production problems.

Capillary Pressure Measurements, conducted by porous plate or heated ultra-centrifuge, provides Air/Brine or Oil/Brine capillary curves for evaluation of reservoir hydrocarbon saturations.

Wettability Evaluation is conducted by a combined AMOTT/USBM test procedure that effectively differentiates between mixed and neutral wettabilities in addition to basic oil versus water wet conditions.

Formation Resistivity Parameters (a, m, and n) are unique to a specific reservoir and need to be measured on reservoir core samples to allow accurate evaluation of downhole electrical logs for water saturation determination.

Relative Permeability Parameters, measured at full reservoir conditions of pressure and temperature, are essential for reservoir simulations to predict recoverable reserves and to evaluate the economic impact of water floods or other enhanced recovery schemes.

Liquid Permeability Recovery Tests provide the most accurate evaluation of any detrimental effects of subjecting a reservoir to foreign fluids such as drilling mud, completion or workover fluids or injection water for water flood implementation.

Drilling Mud Leakoff Tests provide an accurate evaluation of leakoff control and formation damage for proposed mud systems for horizontal drilling applications.

DETAILED RESERVOIR FLUID (PVT) STUDIES are conducted on representative reservoir hydrocarbon fluids acquired through downhole sampling or recombination of surface separator samples. The data generated through these services is essential for the predication of reservoir performance and product mix throughout the producing life of the reservoir.

Differential Displacement Tests simulate the pressure depletion process, which occurs during production and predicts the changes in fluid properties associated with the evolution of gas from the oil or the condensation of liquids from a rich gas system.

Pressure-Volume Relationship Tests document the volumetric changes to the fluid system as the reservoir pressure declines during fluid production.

Live Oil Viscosity Tests evaluate the effects on the fluid viscosity both above and below the saturation pressure of the hydrocarbon system to predict any decline in production rates.

Separator Flash Tests are conducted to evaluate changes in product mix (GOR and composition) resulting from changes in surface processing equipment conditions to allow optimization of the economic value of the produced hydrocarbons.

Field Sampling Services are provided by AGAT’s trained personnel to ensure representative hydrocarbon fluid samples are collected from surface separators or with AGAT’s downhole sampling tools.

SCALE AND CORROSION SERVICES evaluate potential production problems associated with handling produced and/or make-up water in both the surface facilities and injection into the reservoir. Scale and corrosion inhibitor products can be evaluated to minimize the problems associated with the identified scale formation or equipment corrosion.

Water Compatibility Simulation Modeling, conducted by Slomeneq.88 thermodynamic computer program, will identify any potential scale formation in produced waters or associated with the mixing of injection brines from differing formations.

Physical Compatibility Tests confirm the types of scales which form and the rates at which they form. XRD and SEM/XES analyses are used to identify the scales formed.

Scale Inhibitor Evaluation is conducted by a modified NACE standard test procedure, utilizing the actual formation and injection waters. Testing can be conducted at ambient conditions to simulate surface facilities or at full reservoir conditions of pressure and temperature.

Dynamic Wheel Corrosion Inhibitor Tests are conducted at elevated pressure and temperature using actual reservoir brine solutions. AGAT’s custom designed pressurized test apparatus allows the inclusion of the correct partial pressures of corrosive gases (H2S and CO2) to accurately simulate field production conditions.

Field Consulting Services are available utilizing highly trained and experienced technical staff, to evaluate production facilities and to implement recommended scale and/or corrosion inhibitor processes.
