Storengy, one of the leading operators of natural gas storage in the world, will conduct the technical audit for each gas storage facility. After the initial data analysis, the team will visit the sites and provide a detailed technical assessment.
The legal aspect of the study also includes drafting laws, bylaws and decisions. Ukraine intends to expand the use of the storage facilities, including through the development of attractive access conditions for international customers. Storengy, a subsidiary of ENGIE, designs, builds and operates storage facilities for 60 years, owning 21 sites in France, Germany and the United Kingdom with a total capacity of As an active player in the energy transition, Storengy offers its technical expertise to numerous partners around the world.
Risk Management Plans. The operator of an underground gas storage project is required to submit a project-specific Risk Management Plan for Division review and approval.
The operator of an existing underground gas storage project must submit a Risk Management Plan within six months of the effective date of the rules. Emergency Response Plan.
The operator of an underground gas storage project must have an emergency response plan approved by the Division and ready for immediate implementation. The emergency response plan must specify a schedule for carrying out drills to validate the plan.
The operator of an underground gas storage project will be required to provide the Division with highly detailed data, analysis, and interpretation that demonstrate that stored gas will be confined to the approved zone s of injection and that the underground gas storage project will not cause damage to life, health, property, the environment, or natural resources. Operators of existing underground gas storage projects must submit revised and updated project data within days of the effective date of the rules.
Evaluation of Wells Within the Area of Review. The rule specifies minimum requirements, which the Division may augment on a project-specific basis, that are intended to ensure that wells within the area of review will not be a potential conduit for migration outside the approved gas storage zone.
Underground Gas Storage
Records Management. The operator of an underground gas storage project must prepare and submit to the Division a Records Management Program designed to ensure that essential information is created, maintained, protected, and retrievable when needed. Certain records are to be maintained for the lifetime of the project.
Well Construction Requirements.
Underground natural gas storage facility operators will be required to design, construct, modify, and maintain gas storage wells and every other well that penetrates the gas storage reservoir so that mechanical integrity is effectively ensured under anticipated operating conditions. The operator must ensure that a single point of failure does not pose an immediate threat of loss of control of natural gas and other fluids. Mechanical Integrity Testing.
Underground Gas Storage Facilities, Design and Implementation -- Flanigan, Orin -ѕ©¶«ФД¶Б-ФЪПЯФД¶Б
Each gas storage well and every other well that penetrates the gas storage reservoir must be tested in multiple ways: A temperature and noise log shall be conducted at least annually. A casing wall thickness inspection to estimate internal and external corrosion shall be performed at least once every 24 months. Pressure testing of the production casing shall be conducted at a minimum frequency determined on a well-by-well basis. If the Division has not approved a well-specific minimum pressure testing frequency for a well, the operator shall pressure test the well at least once every 24 months.

Monitoring Requirements. The underground gas storage facility operator will be required to monitor for the presence of gas in all well annuli by measuring and recording annular and tubing pressure at least once a day. The operator shall monitor the material balance of an underground gas storage project and shall submit material balance support data to the Division at least once a year.
