Auditing in the process of cementing includes the following:

• Sampling to determine matching of cement slurries and chemical reagents at fields and field sites of service companies, designed to prepare cement slurries in accordance with с GOST 30515-97, ISO 10426-1, ISO 10426-2.

• Complete research of characteristics of cement slurries in accordance with norms of ТУ (engineering specifications), GOST (State standard), and ISO.

• Physical verification of documentation for equipment operated under high pressure, and documentation for cementing reagents.

• Verification of compliance with the norms and requirements in accordance with HSE.

The accredited laboratory’s testing process includes the following:

• Performing physical and chemical research of characteristics of cement slurries for compliance with the requirements of normative documentation of GOST, ISO, statement of work, or other project related documentation.

• Issue of analysis reports with conclusions on existing deviations in cement slurries.

Technical experts’ report:

• Issue of output from analytics of the quality of cement slurries, buffers, applied cements, chemical reagents and additives, based on monitoring.

• The analysis of complications arising during well cementing process.

• Issue of recommendations on selection of formulas of cement slurries, risk assessment.
