There is a relationship between the economic requirements for the development of oil and gas facilities in the oil-producing regions of the North and the environmental problems of sustainable development. One of the ways to solve this problem is the wider use of underground gas storage facilities both for reducing peak loads in the Unified Gas Supply System by collecting and storing previously flared associated petroleum gas, and for burying a large volume of industrial emissions that are harmful to the environment. We have considered a mathematical model of an automated control system for the creation and operation of underground gas storage in the horizons of a depleted oil and gas condensate field with its subsequent use for disposal of industrial emissions. To ensure the stability of the functioning of objects of accumulation and consumption, it is necessary to calculate the depth of feedback for each component of the component: proportional, integral, differential.

Oil tank operation efficiency highly depends on the bottom sediments clean out technologies. In order to monitor oil tank efficiency and provide design improvements certain electro-physical studies were performed. These studies allowed to find the homogeneity conditions; oil-water phase boundary; monitor and identify the state of matter and lead to significant design improvements. It was proposed to update design and arrangement of the inlet and outlet nozzles of oil tank and place them in opposite sides of tank. Along with continuous electro-physical monitoring of the phase boundaries new design allows to increase overall efficiency of oil tank.
