  • Determination Methods of Geological Resources,Recoverable Resources and Well-Controlled Recoverable Reserves in Shale Gas Reservoir
    Xinjiang Petroleum Geology, 2020
    Co-Authors: Chen Yuanqia
    Abstract:

    The main component of shale Gas is methane accounting for 98.5%,with minor amounts of ethane,propane,helium,oxygen and carbon dioxide Gas.Shale Gas Reservoir is a kind of special Closed Gas Reservoir,and it is composed of extra-dense matrix and micro-fracture system.Gas in matrix is stored in a state of saturated adsorption on the surface of particles ranging from nanometers(10-9m) to micrometer(10-6m);natural Gas in micro-fracture is existed in a free state into the micro-fractures,and they belong to one pressure-balanced system.Shale has larger density,while fracture has small porosity,therefore,adsorbed Gas is the main reserves of shale Gas.Currently,the evaluation methods for shale Gas resources reported in the literatures are incorrect,hence the results are unreliable.This paper presents the volume method for geological resources,the dynamic balance method for recoverable resources and the production decline method for well-controlled recoverable reserves in shale Gas Reservoirs.

  • A new method to determine reasonable well pattern density in low-permeability Gas Reservoirs
    Journal of Petroleum Exploration and Production Technology, 2019
    Co-Authors: Tianjin Zhang, Hu Xia, Chunsheng Li, Zhisheng Zhang, Hailong Liu
    Abstract:

    The productivity evaluation of Gas Reservoirs is used to determine the optimal number of well pattern, which is an important part of the preparation of Gas Reservoir development plan. Using integral transformation and asymptotic analyses to solve the pseudo steady-state flow model in Closed rectangular Gas Reservoir of constant thickness, analytic solution of pressure distribution of eccentric well can be obtained. This paper presents mathematical model of multiple wells producing from a Closed Gas Reservoir by applying the principle of pressure superposition. The pseudo steady-state dimensionless production index is introduced to solve the multiple well mathematical models under the constant pressure, and the number of production wells and cumulative production in different production interval are obtained. The results of the calculation shows that the curve of the cumulative production and economic benefits have a maximum value when the producing time, Gas price, and drilling costs are given, so it can determine the optimal number of wells and provide the basis for making Gas Reservoir development plan.

  • Determination of well pattern density in low permeability Gas Reservoirs based on dynamic single well production
    Journal of Northeast Petroleum University, 2020
    Co-Authors: Liu Hailon
    Abstract:

    Using productivity evaluation of Gas Reservoirs to determine the optimal number of well pattern is an important part of the preparation of Gas Reservoir development plan.Using integral transformation and asymptotic analyses to solve the pseudo steady-state flow model in Closed rectangular Gas Reservoir of constant thickness,analytic solution of pressure distribution of eccentric well can be obtained.This paper presents mathematical model of multiple wells producing from a Closed Gas Reservoir by applying principle of pressure superposition.And by introducing the pseudo steady-state dimensionless production index to solve the multiple wells mathematical model under the constant pressure,the number of production and cumulative production as well in different production interval is well obtained.The results of calculation show that the curve of the number of cumulative production and economic benefits as well has a maximum value when giving the years of production,Gas price and drilling costs,so it can determine the optimal number of wells and provide the basis for making Gas Reservoir development plan.
