A wide range of professional reservoir description services are offered by PetroAzma and its distinguished partners and associates to the oil and gas industry.  These services include: 


Core Preparation


The core analysis workflow starts immediately by core preparation upon arrival of the core barrels to our Laboratory. This preparation starts with layout, cleaning, measuring and mark-up of the core. During these operations close attention is paid to the proper matching and orientation of core fragments. The samples used in such studies should be as representative as possible of the reservoir rock at depth if the final data is to be credible, and an efficient use of the financial resources devoted to them. These plugs are obtained by drilling cylinders from the core using appropriate drilling fluid such as brine or oil and trimming the ends of these cylindrical samples. Samples of the reservoir rock and fluid are commonly altered by the process of obtaining them (coring, recovery, well-site handling, shipment, storage, and preparation for experimentation).This process is carefully considered and appropriate preparation strategy is employed. Standard prepared plugs are then used for determination of oil and water saturation, porosity, permeability, grain density measurements (at ambient pressure or at higher pressures to mimic subsurface conditions) and for a variety of Special Core Analysis tests.

Routine Core Analysis


Routine (Conventional) Core Analysis (RCAL or CCAL) attempts to give the very basic petro-physical properties of unpreserved and cleaned state core plugs or outcrop samples. The routine data provide a useful guide to well and reservoir performance of different formations such as sandstone, un-consolidated sediment, carbonate, shale, and coal. Core samples may be taken either in vertical, horizontal or inclined orientations depending on the objectives of the study. Routine core analysis usually includes measurement of porosity, air permeability, fluid saturations, grain density, and determination of lithology and texture. It could also cover the core gamma photography.

PVT Analysis


Reservoir fluid analysis laboratory in PetroAzma offers comprehensive Pressure-Volume-Temperature (PVT) studies for all reservoir fluid types to provide complete picture of any hydrocarbon sample using advanced and latest equipment. Our well-experienced and specially trained staff can provide accurate PVT analysis, which is vital for precisely calculation and evaluation the value of the reserve. PVT fluid studies can be performed on validated recombined surface separator samples or subsurface reservoir samples.

Special Core Analysis


Special Core Analysis (SCAL) attempts to extend the data provided by routine measurements to situations, which are further representative of reservoir conditions. Special core analysis usually includes measurement of porosity and permeability at reservoir conditions, capillary pressure, relative permeability, rock electrical properties, cation exchange capacity, X-ray computerized tomography (CT), acoustical properties, residual saturations, preferential wettability and core flood and EOR tests. SCAL data is usually used to support log and well test data in gaining an understanding of individual well and overall reservoir performance.
