What is the capping capacity of a gas storage reservoir?
For a gas storage reservoir, the capping capacity of the cap is the ability of the reservoir to prevent the escape of natural gas, which controls the vertical distribution, abundance, and working pressure of natural gas in the reservoir (Liu et al. ).
Should energy storage be used in depleted oil and gas reservoirs?
Utilizing energy storage in depleted oil and gas reservoirs can improve productivity while reducing power costs and is one of the best ways to achieve synergistic development of "Carbon Peak–Carbon Neutral" and "Underground Resource Utilization".
How does ground stress affect a gas storage reservoir?
The ground stress field in a gas storage reservoir varies cyclically with the injection and extraction cycles. In addition to varying degrees of elastic–plastic deformation, localized stress concentrations may be induced, and such stress concentrations can accumulate in the rock and form fatigue damage.
Can CO2 be stored in natural gas fields?
Case studies on the potential for CO 2 storage in natural gas fields. – Methods for monitoring and verifying CO 2 injection were developed, which can be utilized in future commercial-scale projects of CO 2 subsurface storage. – The available storage pore volume in the formation equals 1.45 × 10 7 tonnes of CO 2.
What are the types of gas storage?
The types of gas storage include salt cavern, depleted oil and gas reservoir and aquifer. The surrounding rock of salt cavern has good creep property and the high salt content can inhibit some microorganisms, but the suitable sites are few and the gas storage is limited. Aquifers have large gas storage capacity.
What is underground gas storage?
There is a need to study the gas mixtures underground for storage. The concept of underground gas storage is based on the natural capacity of geological formations such as aquifers, depleted oil and gas reservoirs, and salt caverns to store gases.
