Abstract

Abstract: Large-scale development of shale gas in China is at the initial stage. Unscientific valuation methods present a major challenge to the optimization management of drilling investment. This paper proposes a set of optimization analysis methods for drilling investment: "valuation method integration + standard well management". The purpose of valuation method integration is to establish a valuation method system for drilling engineering which will meet the needs of the entire process of management of oil and gas exploration and development projects. The premise is to establish unified and standardized calculation rules for the bills of quantities for drilling engineering, cost composition of drilling engineering projects, and a standard valuation system for the whole process of drilling engineering. The standard well management process is to establish several standard well projects for scientific investment decision-making and organization of drilling operation. These methods were applied in the calculation of development well investment and the optimization analysis of cost reducing and benefit increasing in CNPC's special planning for shale gas development in 2021-2030. This paper introduces the analysis of drilling productivity levels and preparation of budget quotas. There are 6 main functions: rough calculation quotas; rough calculation indicators; estimation indicators; reference indicators, and the methods and results of drilling investment calculations.

Key words: shale gas, drilling, investment, integration, standard well, bill of quantities, valuation method, valuation standard, cost reducing and benefit increasing, planning
