The California Memorandum of Subsurface Underground Gas Storage Lease and Agreement is a legally binding document that defines the terms and conditions for the leasing and agreement of underground gas storage facilities in the state of California. This agreement provides a framework for the proper operation and regulation of these facilities, ensuring safety standards and environmental regulations are met. Under this agreement, the lessor grants the lessee the right to use a specific area of subsurface land for the purpose of underground gas storage. The lease outlines the duration of the agreement, the terms of payment, and any additional responsibilities or requirements that must be fulfilled by both parties. There are various types of California Memorandum of Subsurface Underground Gas Storage Lease and Agreement, based on different factors such as the size and capacity of the storage facility, location, and the specific gas storage method used. Some key types include: 1. Depleted Reservoir Lease: This type of agreement involves using depleted oil or gas reservoirs for underground gas storage. These reservoirs are no longer productive but have the capacity to store large quantities of gas. 2. Aquifer Storage Lease: Under this agreement, the lessee has the right to use underground aquifers for gas storage. Aquifers are usually porous and can hold significant amounts of gas. 3. Salt Cavern Storage Lease: Salt caverns are another possibility for underground gas storage. This type of agreement grants the lessee access to utilize these caverns for storing gas. Salt caverns provide advantages like high deliverability rates and can store large volumes of gas. 4. Solution-mined Cavern Storage Lease: This agreement pertains to using solution-mined caverns in underground salt formations for gas storage. In this process, water or brine is injected into the salt formation to dissolve it, creating storage space for gas. It's important to note that these agreements must adhere to California state laws and regulations governing gas storage operations. The California Memorandum of Subsurface Underground Gas Storage Lease and Agreement aims to ensure the safe and responsible storage of gas, promoting environmental protection, and minimizing any potential risks associated with these activities.
