Abstract
The article introduces the problems of choosing a methodological base for forming and accounting costs during well construction, taking into account the intensification of gas inflow at the final stage of field development. The main methods that allow taking into account the costs of drilling operations are outlined. The main costs that need to be taken into account when designing fields with hard-to-recover gas reserves are identified and characterized. The main stages of cost formation by construction phases of a gas-producing well are shown, as well as the factors influencing the level and structure of the cost price during the construction of a well are highlighted. The authors consider the classification of cost accounting methods in the context of the comparison criterion and present the possible results of the correct choice of the cost formation method during the construction of a gas well at the final stage of its development.
Highlights
The article introduces the problems of choosing a methodological base for forming and accounting costs during well construction, taking into account the intensification of gas inflow at the final stage of field development
One of the conditions for reducing the gas production cost is the implementation of a consistent saving mode at all stages of well construction, primarily this is aimed at reducing the cost of material resources cost of servicing the production process of well construction and management, as well as eliminating losses from defects, and other unproductive expenses
The choice of a methodological basis for forming and accounting costs during well construction must consider that gas inflow intensification is reached at the final stage of field development
Summary
The article introduces the problems of choosing a methodological base for forming and accounting costs during well construction, taking into account the intensification of gas inflow at the final stage of field development. The reserves of high-quality hard-to-recover raw hydrocarbons within the known and exploited areas are especially valuable Their development and operation require attracting additional costs for the development of social, industrial, and transport infrastructure, which is the main factor affecting the cost of drilling operations during well construction. In the context of insufficiency of various types of resources, such as financial, economic, investment, etc., due to the unstable macroeconomic situation and changes in the development trends of the world energy market, the problem of reducing the level of costs is becoming very urgent First of all, this concerns the work on intensifying the inflow of hard-to-recover hydrocarbon reserves, in terms of drilling operations. The development and construction of wells with hard-to-recover gas reserves are considered to be successfully implemented when setting and implementing a goal, such as achieving the estimated minimum increment in gas production while reducing the extraction of associated water in the conditions of the stable near the well-bore area to improve the economic efficiency of the work performed in general (Vaganov y Kustyshev, 2016; Vaganov y Cheymetova, 2020)
