Western Siberia is Russia’s main oil and gas productive area. Industrial plants here have huge adverse environmental impact which is why they are considered to use the best available technologies when developing the project solutions within their license blocks. The Russian environmental laws promote the oil and gas companies to approach the best available technologies. In the process of oil production the companies could use an innovative mud pit for temporary storage of drilling waste. A new technology is oriented to achieve, suppose building a structure for temporary storage of drilling waste which provides advanced environmental safety.
The innovative drilling mud storage technology is designed to build a mud pit with watertight screen on the bottom and walls of it, and to create conditions for further rehabilitation of the mud storage facilities. Resource advantage of the proposed technology is the use of modular enclosure structures which assigns the innovative mud pit to capital construction. Unlike the temporary facilities the capital construction facilities allow collecting and dumping wastes, as well as storage and burying. The technology of using modular enclosure structure based on recycling and low material consumption is unique. It reduces costs for construction of new waste storage facility, as well as acts as a primary element of the environmental safety system when implementing construction of structures and facilities in the license holders’ blocks. Thanks to this mud pit construction technology atmospheric precipitation ingress does not occur to the stored mud. Instead, it runs down outside the fencing structure and off the field. Ground water cannot penetrate into the pit, so that water soluble hazardous substances cannot be carried out from the pit.
The innovative mud pit technology ensures the increased environmental safety and efficiency in drilling mud handling. The costs for its implementation remunerate operating expenses of the license holder in terms of disposal fee for wastes generated from drilling, that reduces profit tax base. Allowance collected by the license holder for the value of the implemented technologies will be a significant incentive to adopt the new technologies when implementing oil production project solutions in the license block, which is a new generating stage in development of oil and gas production in Western Siberia.
