Geofluids, Volume 2021, Issue 1, 2021., 2021 In recent years, greenhouse gases have increased in the atmosphere, and climate change concerns have triggered global efforts to find solutions for CO2 capture, separation, transport, and storage. Geological sequestration in the depleted unconventional reservoir is an effective measure to reduce the atmosphere’s CO2 content. The exact evaluation of the

A Semianalytical Two‐Phase Imbibition Model in Dual‐Porosity and Dual‐Permeability Reservoirs
Geofluids, Volume 2021, Issue 1, 2021., 2021 The pressure transient behavior of water injection well has been extensively investigated under single‐phase flow conditions. However, when water is injected into formation, there are saturation gradients within the water flooded area. Additionally, water imbibition is essentially important for oil displacement in dual‐porosity and dual‐permeability ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 For constant rate production of a single well in a closed boundary fractured‐vuggy carbonate reservoir, when the pressure wave propagates to the reservoir boundaries, boundary‐dominated flow occurs, and the transient flow period ends, the reservoir will be in a state of pseudoequilibrium (i.e., pseudosteady state flow occurs, and the pressure at any ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 Carbonate reservoirs are mainly fractured‐caved reservoirs with very well‐developed dissolved pores, fractures, and caves. They have strong heterogeneity with various types of reservoir pore spaces. Using seismic inversion and reservoir static characterization, the result shows that the fractured‐caved carbonate rocks in China are mainly caves with ...

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Naturally fractured reservoirs (NFR) represent an important percentage of worldwide hydrocarbon reserves and production. The performance of naturally fractured gas condensate reservoirs would be more complicated regarding both rock and fluid effects. In contrast to the dual‐porosity model, dual‐porosity/dual‐permeability (dual‐permeability) model is ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 Fractured horizontal wells have been widely used to develop unconventional oil and gas reservoirs. In previous studies, most studies on the transient pressure behavior of multistage horizontal wells were based on the assumption of single porosity medium, in which the coupling relationship of natural fractures and artificial fractures was not taken into

Performance evaluation of multiple fractured horizontal wells in shale gas reservoirs
Energy Science &Engineering, Volume 8, Issue 10, Page 3657-3671, October 2020., 2020 In this paper, a triple‐porosity dual‐permeability model is developed for simulating the flow mechanism of shale gas. Different lengths and widths of network fractures, different fracture intervals, and asymmetry distribution are considered in this model.

Geofluids, Volume 2020, Issue 1, 2020., 2020 Carbonate reservoirs typically have complex pore structures, so the production wells typically have high production in the early production stage, but they decline rapidly. It is highly challenging to achieve accurate interpretation results. In this paper, a new and practical methodology for production data analysis of fractured and fractured‐vuggy ...

Novel, Integrated and Revolutionary Well Test Interpretation and Analysis [PDF]
, 2018 Well test interpretation is an important tool for reservoir characterization. There exist four methods to achieve this goal, which are as follows: type‐curve matching, conventional straight‐line method, non‐linear regression analysis, and TDS technique ...
