Equipment Hire Core Lab supplies a wide variety of oilfield analysis equipment on a short- or long-term hire basis. The available items include gas chromatograph, Coulter Counter, Karl Fisher, Miran, Hach spectrophotometer and centrifuge equipment. On-site training and test procedures are also available upon request.

Mobile PVT Laboratories
Core Lab's mobile laboratories are currently being used for wellsite restoration, sample validation and the evaluation of oil-based mud filtrate contamination. This is particularly important for proving, validating and transfering samples from open hole tools such MDT or RCI chambers. The mobile laboratories are also used where a quick analysis is essential to the client and in overseas and remote locations where it would prove difficult to export samples.

Oil and Gas Analysis
Core Lab chemists routinely perform on-site oil and gas measurements during well tests to determine fluid properties. The measurements include gas composition testing for carbon dioxide, hydrogen sulfide and other sulfur species, as well as mercury and radon. Hydrogen sulfide, mercaptans and mercury contents are determined on site due to the associated losses within sample cylinders.

Surface Oil and Gas Sampling
Hydrocarbon sampling is provided by our PVT-trained sampling engineers. With our extensive range of high-pressure cylinders, we can collect samples from the wellhead, test separator and any other process points. We also offer on-site sample validation and transfer of open-hole tools such as MDT or RCI chambers.

Subsurface Sampling
Core Lab sampling specialists provide both Single Phase Bottom Hole and Positive Displacement Sampling Services with a maximum working pressure to 15,000 psi and maximum working temperature to 350°F. Single phase bottom hole samples are the best means of obtaining uncontaminated and representative Reservoir Fluids. This is particulary important with regard to flow assurance and Asphaltene deposition in particular.

Water Analysis
Produced water is collected and analyzed to determine the fluid composition and likely origin. The Ca2+, Cl-, Mg2+, Ba2+, HCO3-, S2-, SO4-, Fe, and other ion concentrations are determined as well as the pH, resistivity and specific gravity of the fluid. Personnel can also be supplied to plan, coordinate and collect samples during chemical squeeze treatments.

Core Handling Services
Core Lab's specially trained core analysts perform various on-site core handling services. Their global experience in many different locations, climates and difficult operating conditions qualify these technicians to identify and solve problems which may have a direct or indirect impact on core quality. The services include core catching, plugging, core stabilization by resin injection, and preservation by resin encasement.
