Core Analysis quality assurance starts with correct wellsite handling. It is vital that the personnel handling the core at the wellsite be fully trained and aware of the need for careful attention to be given to the orientation, marking and preservation of the core.

Proper packing will ensure cores arrive at the core analysis laboratory in the best condition and without jeopardising the core integrity. Any delay in sampling of the cores can result in alteration of the fluid distribution within the cores thus impacting subsequent analyses.

COREX are able to provide experienced trained staff to carry out the following wellsite services; 

  • Wellsite Core Technician Hire
  • Core catching and initial handling
  • Core Processing

Core Stabilisation

It has been widely acknowledged that core handling is critical to the preservation of core integrity.


You can depend upon COREX rapid deployment wellsite team to handle to prepare, stabilise and handle your core are the wellsite assuring the accuracy of core data produced at the testing laboratory is maintained to the highest level. The accuracy of data and economic impact of quality analysis can be fully realised protecting your investment and maximising your benefit by choosing COREX as your preferred contractor for wellsite core stabilisation.

We offer a range of advanced methods for core stabilisation. Quality stabilisation managed alongside the expert project management and quality control of core handling at the well site, safeguards core quality when it arrives at the analytical lab. As independent experts in wellsite services Corex can provide highly valued reports and recommendations as part of a pre-study therefore producing high quality reservoir data at an early stage. These services can be also offered in the laboratory, for forward transport.

The main drive of core preservation is to preserve the pore fluids in the stabilised core samples thus preventing saturation and wettability alteration. COREX utilise a high quality wax which has superior sealing and preservation properties for short and long term storage of core material.

 

Consignment Shock Recording

Transportation knocks and bumps are recorded by an accelerometer with a triaxial

sensor inside the core container or core barrel.

Recording shocks (in 3 directions) and the free fall height recording the duration and the energy of a shock. The accelerometer provides the following specifications:

Range +/- 6G. 75Hz, temperature range from -20⁰C to +40⁰C we use accelerometers to measure transportation shocks and assist in loss prevention of the very valuable rock samples, fluids and gases, as they are transported from the wellsite to the COREX analytical laboratories.

 

Wellsite Core Handling Consultancy

Accurate core analysis programs, begin at the wellsite, COREX  consultants will also ensure the core analysis program, SCAL program, reservoir geology study and reservoir rock type exploration program is designed to match the best coring procedures. To assist in this task an experienced coring supervisor, wellsite geologist, core analysis specialist, petrophysicist, reservoir geologist, rock mechanics engineers are available to assist with program design and management.

 

Digital Core Photography

Our highly trained rapid deployment wellsite team have a range of portable equipment which can be easily transported to wellsite offshore or onshore.
