Introduction

National Standard of the People's Republic of China GB/T 43125—2023: In-depth Interpretation of Technical Specifications for Shale Oil Productivity Evaluation

Evaluation method	Applicable conditions	Key parameters	Advantages and disadvantages analysis
Analytical method	Applicable when well test data is available	Effective permeability, fracture effective half-length, fracture conductivity, etc.	High accuracy, but requires high-quality data support
Decline method	Applicable when production data for more than 12 months is available	Reservoir thickness, permeability, crude oil viscosity, etc.	Simple and easy, but sensitive to later data
Numerical simulation method	Applicable when a geological model can be established	Ground stress, pore pressure, fracture distribution, etc.	High accuracy, but high calculation complexity

Standard formulation background and technology evolution analysis

Shale oil production capacity evaluation technical specifications are formulated to meet the needs of my country's unconventional oil and gas resource development. With the transformation of energy structure and the rapid development of shale oil technology, this standard fills the gap in the field of shale oil production capacity evaluation in China.

Implementation suggestions for shale oil production capacity evaluation methods

Data acquisition and processing: Ensure the integrity of production well dynamic data and avoid interference from outliers.
Model optimization: Select the optimal evaluation model (such as Arps decline model, Duong model, etc.) according to regional geological conditions.
Economic indicator considerations: Comprehensively consider oil and gas commodity rates, taxes and production costs to determine a reasonable economic lower limit.
