Sub-Surface Sampling Services
Our sampling solutions are designed to preserve original reservoir conditions, ensuring reliable laboratory results for critical engineering and economic decisions.
Our services cover downhole fluid sampling, surface sample transfer, pressurized sample storage, and handling, using advanced sampling systems suitable for high-pressure and high-temperature well environments.
We provide downhole fluid sampling services using positive displacement and single-phase sampling techniques to obtain contamination-free, representative reservoir fluids directly from the wellbore.
- Accurate collection of reservoir fluids at downhole conditions
- Prevention of contamination before and after sampling
- Reliable sample volume confirmation
- Controlled sampling duration for precise results
Our sampling methods ensure:
For challenging fluids containing asphaltenes, paraffins, or viscous components, we offer single-phase sampling, which maintains the sample above bubble or dew point throughout the entire operation to preserve true reservoir fluid properties.
After retrieval to surface, samples are transferred using high-pressure field transfer units into piston-type pressurized sample cylinders. These cylinders are designed for safe transportation and storage of hydrocarbon samples while maintaining pressure integrity.
- Controlled and safe sample transfer
- High-pressure capability for surface and subsurface samples
- Minimal dead volume to preserve sample quality
- Secure handling during transport to laboratory facilities
Key features include:
- Sample transfer at reservoir temperature
- Improved flow characteristics during surface handling
- Reduced risk of phase change or blockage
Heating & Sample Conditioning:
For viscous fluids or samples containing waxes and asphaltenes, we provide heating jackets for both sample chambers and sample cylinders. These allow:
- Mechanical time-delay triggering systems for downhole samplers
- Nitrogen pressurization systems to maintain sample pressure
- Dedicated tool kits to ensure efficient and safe field operations
Sampling Support Equipment:
Our sampling services are supported by a complete range of operating tools and accessories, including:
- Representative, contamination-free reservoir fluid samples
- Suitable for high-pressure, high-temperature wells
- Single-phase sampling capability for complex fluids
- Safe, controlled transfer and transportation
- Reliable data for reservoir studies and PVT analysis
