High-Pressure, High-Temperature Gamma Ray Spectroscopy Measurements in the Oil Field: Data Quality Improvements Using Cerium-Doped Lanthanum Bromide Scintillation Crystal [PDF]

EPJ Web of Conferences
In the oilfield industry, exploration of the subsurface is essential to answer questions regarding location, type, quantity, and producibility of hydrocarbons. The environment in which these measurements are made can be severe.

Modeling and monitoring injectivity evolution during cold CO2 injection with field evidence from aquistore carbon capture and storage operations

Deep Underground Science and Engineering, EarlyView.
This work integrates 5 years of field data from the Aquistore CCS project with a non‐isothermal THM modeling framework to explain how cold CO2 injection alters injectivity over time. The study shows that sustained cooling near the wellbore reduces effective stresses, promotes tensile micro‑cracking, and leads to semi‑reversible permeability enhancement

Integrated modeling of a complex oil rim development scenario under subsurface uncertainty

Journal of Petroleum Exploration and Production Technology, 2019
Evaluation of the economic benefit of field development projects in the oil and gas industry is naturally subject to subsurface uncertainties and risks.

Root cause of sand production and methodologies for prediction

Petroleum, 2021
The consequences of sandstone reservoir rock failure may lead to sand production. This phenomenon can have negative impact on lifting cost and economic of any field development.

3D seismic imagery of a buried glacitectonic thrust complex in the North Sea and the dimensions of composite ridge systems in glaciated landscapes

Journal of Quaternary Science, EarlyView.
ABSTRACT Sets of sub‐parallel composite ridges in glaciated landscapes have long been regarded as landforms produced by glacitectonism, the brittle and ductile deformation of sediments at and immediately beyond glacier and ice‐sheet margins resulting from stresses produced by ice.

Understanding the origin of hydrogen sulphide in South-Western Gissar, Southern Uzbekistan

All Earth
Hydrogen sulphide (H2S) concentrations across three adjacent gas condensate fields in Southwestern Gissar produced from fractured Middle-Upper Jurassic reef-carbonates with anhydrite-bearing beds have been analysed. Wellsite testing measurements followed

3D finite element modelling of multilateral junction wellbore stability

Petroleum Science, 2018
Wellbore failure can occur at different stages of operations. For example, wellbore collapse might happen during drilling and/or during production. The drilling process results in the removal of an already stressed rock material.

Geomechanical modelling of cold heavy oil production with sand

Petroleum, 2022
The contribution of geomechanics to provide a rigorous quantification of porosity changes and associated permeability changes is often neglected when considering hydrocarbon production.
