Clay stabilization in sandstone reservoirs and the perspectives for shale reservoirs

Advances in Colloid and Interface Science, 2020
This study presents a comprehensive review of clay stabilizers and updated understandings of their mechanisms on stabilizing clay minerals in improved and enhanced oil recovery (IOR and EOR) applications. First, formation damage mechanisms related to clays in conventional sandstone and shale reservoirs are briefly introduced.

Optimisation of hydraulic fracturing parameters based on cohesive zone method in oil shale reservoir with random distribution of weak planes

, 2020
Hydraulic fracturing technology plays a key role in the in-situ exploitation of oil shale. A mechanism for generating complex fracture networks in oil shale reservoirs with randomly distribution weak planes is of vital importance to hydraulic fracturing ...

Characteristics of Shale Reservoirs

2016
Shale gas reservoir shows several features dissimilar with conventional reservoir which make it difficult to understand behavior of it. In this chapter, these features such as natural fracture system, adsorption/desorption of gas, diffusion in nanopores, non-Darcy flow, and stress-dependent compaction are presented.

Unconventional Measures for Shale Reservoirs

Journal of Petroleum Technology, 2016
Unconventional Measures for Shale Reservoirs Stephen Rassenfoss, JPT Emerging Technology Senior Editor One of the biggest ways to lower the cost of production from shale would be to identify zones that are productive, or not, before fracturing them.

A Semi-Analytical Model of a Hydraulically Fractured Horizontal Well with Pre-Darcy Flow and Stimulated Reservoir Volume in a Radial Composite Shale Reservoir

SPE Journal
Due to the low porosity and permeability of the shale matrix, multi-fractured horizontal well (MFHW) is one of the most well-known technologies to promote the withdrawal of shale oil.

The study of fracture propagation in pre-acidized shale reservoir during the hydraulic fracturing

, 2020
Due to the high stress difference, high breakdown pressure and undeveloped natural fracture, the pre-acidizing treatment is an effective method for deep shale reservoir hydraulic fracturing.

Differential Characteristics of the Upper Ordovician‐Lower Silurian Wufeng‐Longmaxi Shale Reservoir and its Implications for Exploration and Development of Shale Gas in/around the Sichuan Basin

Acta Geologica Sinica (English), 2019
The Upper Ordovician Wufeng‐Lower Silurian Longmaxi shale is widely distributed in the Sichuan Basin and its periphery, which is the key stratum for marine shale gas exploration and development (E&D) in China.

Experimental evaluation of oxidation sensitivity in organic-rich shale reservoir

, 2020
Organic-rich shale reservoirs are rich in reductive minerals, such as pyrite and other organic matters. The working fluid for the development of shale gas reservoirs contains large amount of dissolved oxygen.

Transport behaviors of real gas mixture through nanopores of shale reservoir

Journal of Petroleum Science and Engineering, 2019
The modeling of shale gas transport through nanopores is the basis for shale gas production simulation. The real shale gas always consists of a series of gases, including ethane, propane and hydrogen sulfide etc.
