An Integrated Approach to the Development and Reservation of Gas in Central Yakutia

Abstract

The article provides a detailed overview of diverse problems in gas industry in the Central part of the Republic of Sakha (Yakutia). The problems associated with the provision of recoverable gas reserves, seasonal contrast of produced amounts, production and gas transportation system and the challenges of increasing the gas consumption market are considered in details. A retrospective assessment of the initial geological reserves of natural gas of the Middle-Viluy gas condensate deposit is given. On the basis of production characteristics of deposits and the analysis of development of the worked-out deposits, coefficient of recovery of gas is estimated. It is concluded that under the current system of development of the Middle-Viluy gas condensate deposit, the ratio of the ultimate gas recovery will amount to just 0.5. The inexpediency of construction of boosting compressor station for production of several billion cubic meters of gas is shown. An integrated approach to solving the existing problems of the gas industry is proposed. The necessity of reserving gas raw materials in close proximity to the consumer by creating an subsurface gas storage is noted. It is concluded that only the creation of a gas reservation system will allow to extract most efficiently gas resources of the Central Yakutia and provide the necessary level of energy security.
