Inventory production control: How can oil companies ensure compliance with the new requirements of the Federal Agency for Mineral Resources Regulatory Document

Background. In view of the introduction by the Federal Agency for Mineral Resources of the new regulations of well testing from 1 October 2023, the article considers the issues of technological support of the requirements for the coverage and frequency of instrumental control of the production of recoverable oil reserves during the development of raw hydrocarbon deposits, provided by the regulations. Objective. To develop recommendations to oil companies and subsoil users on fulfillment of the requirements of the new Regulatory Document in conditions of development of highly watered fields under conditions of oil displacement by low-mineralized waters. Materials and methods. The use of logging and production logging methods is shown using the examples of typical Neocomian deposits in Western Siberia. Results. The problem of low quality of hydrodynamic models due to nonuse of well surveying data is analyzed. In conditions of low mineralization of invading waters, low reliability of carbon/oxygen logging is shown. It is proved that oil companies have the opportunity to rely on the on the information content of “active” neutron logging (with artificial injection of mineralized salt solutions), as well as on the interpretation of logging complexes in newly drilled wells. Conclusions. The cardinal solution to the problem of controlling the development of recoverable reserves and, as a result, ensuring the oil recovery factors approved in the new regulations should be observation nonperforated wells with fiberglass or metal liners under conditions of their monitoring by logging and production logging methods.
