Tertiary hydrothermal activity and its effect on reservoir properties in the Xihu Depression, East China Sea

Petroleum Science, 2019
Three large-scale episodes of volcanic activity occurred during the Tertiary in the Xihu Depression, located in the East China Sea. Intermediate-felsic magmas intruded along faults and the associated hydrothermal fluids resulted in the hydrothermal ...

Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

Near Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Integrated numerical simulation of hydraulic fracturing and production in shale gas well considering gas-water two-phase flow

Petroleum Exploration and Development
Based on the displacement discontinuity method and the discrete fracture unified pipe network model, a sequential iterative numerical method was used to build a fracturing-production integrated numerical model of shale gas well considering the two-phase ...

Carbon Populism and Representative Politics: On Why Fossil Fuel Firms Speaking for ‘The People’ Is a Bad Idea

Journal of Management Studies, EarlyView.
Abstract Despite growing recognition that countries around the world must transition to a low‐carbon economy, global greenhouse gas emissions continue to rise. One way that decarbonization has been obstructed, we argue, is by fossil fuel firms intentionally conflating their agenda with ‘the people’, evoking notions of national identity, security and ...

Characteristics of water alternating CO2 injection in low-permeability beach-bar sand reservoirs

Energy Geoscience
Water flooding can be ineffective in highly heterogeneous low-permeability beach-bar sand reservoirs. The introduction of CO2 flooding helps boost the oil production of the reservoirs but only in an early stage.

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

Sedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...
