Problems solved by technology

Since 2009, when the production method was implemented to accrue depletion, SEC (U.S. Securities and Exchange Commission) reserves are the economically recoverable reserves that oil companies listed in the United States must disclose, and they are also the basis and basis for accruing depletion of oil and gas. Therefore, the SEC reserves There is a direct relationship between the size and the depreciation cost. The depreciation cost enters the company to complete the production cost, thus affecting the overall net profit
This patent application only considers the impact of different values ​​of various economic parameters on the return on investment of exploration and development projects, and the impact of investment decision-making results; it does not take into account the difference in project benefits under different investment scales, and does not make a decision on the overall investment scale. generate constraints

Embodiment Construction

[0021] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.

[0022] In oilfield development, as the water cut continues to rise, the development unit must increase the investment in production costs such as measures to maintain a stable or increased production, and as the production rises, the cost increases exponentially, and the cost per ton of oil rises The rate (increased cost / increased output) keeps rising. In addition, to maintain the output of the oil field, there must be incremental investment in new investment projects, and the development of new units will inevitably increase the net asset value; the production, reserves, and net asset value affect each other, especially the depletion cost of the stock, thereby affecting the overall profit.

[0023] Such as figure 1 as shown, figure 1 It is a flow ch...

Abstract

The invention provides an oil production and oil and gas asset loss fee optimization evaluation method. The method comprises the following steps: step 1, dividing calculation and extraction units according to oil reservoir types or development modes by utilizing a clustering analysis method; step 2, determining oil and gas production operation cost and SEC reserves of each metering and extraction unit; step 3, determining the ton oil loss fee of each metering and extracting unit and the oil production capacity of each metering and extracting unit, and obtaining the optimal yield Q1i; step 4, determining stock oil and gas assets and newly added oil and gas asset transfer parameters of each metering and extraction unit; step 5, determining a relationship between newly-added oil and gas asset transfer and yield of each metering and extraction unit, and obtaining an optimal yield Q2i; step 6, optimizing the optimal value Q3i of each counting and extracting unit according to the complete cost of each ton of oil and the ton oil loss fee; and step 7, optimizing the output composition to obtain an optimal output distribution scheme of each unit. The method can reasonably formulate a development strategy for mine field production, determines a new oil and gas asset input direction, better improves the operation effect, and improves the enterprise profit.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to an optimization evaluation method for oil production and depletion of oil and gas assets. Background technique [0002] Depletion of oil and gas assets (hereinafter referred to as depletion) is the value of oil and gas assets gradually transferred to the cost of the extracted product (oil and gas) as the current development progresses. It is an accounting policy for oil and gas that is of concern to the government, the oil and gas industry and related industries One of the focuses, the follow-up measurement of depletion of oil and gas assets is also difficult. Since 2009, when the production method was implemented to accrue depletion, SEC (U.S. Securities and Exchange Commission) reserves are the economically recoverable reserves that oil companies listed in the United States must disclose, and they are also the basis and basis for accruing depletion of oil ...
