As Egypt’s largest oil and gas investor, Eni is ramping up its 2026–2027 drilling campaign with new investments cross the Mediterranean offshore, Nile Delta, Western Desert, and offshore Sinai to strengthen the country’s role as a regional gas and LNG export hub.
This paper presents an experiment investigating dissolution of basaltic primary minerals and conditions favorable for secondary phase formation under deep subsurface storage conditions.
This study aims to investigate the efficacy of chemical additives strontium chloride and barium hydroxide in accelerating CO₂ trapping mechanisms, their effect on dissolution of carbonate-bearing minerals, and resulting poroelastic changes in the host rock.

In hydraulic fracturing, the use of diagnostic-fracture-injection tests (DFITs) can provide valuable information. -
The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR.
-
Recent experience with a newly introduced sampling-while-drilling service has shown that it is possible to make reliable downhole formation-fluid-property estimates during sampling-while-drilling operations.
-
Comprehensive formation evaluation is one of the technical focus areas that is fundamental across almost all upstream businesses.
-
Produced water from chemical floods can cause problems for separation and water treatment equipment due to the polymers and surfactants used. Challenges are greater offshore where space limitations can affect treatment options.
-
In this study, the authors use measured CO2/brine relative permeability data available in the literature to study the behavior of the data obtained for various rocks.
-
This paper introduces a new carbon dioxide (CO2) -hybrid fracturing-fluid design that intends to improve production from ultratight reservoirs and reduces freshwater usage.
-
The combination of technology advances and world politics results in oil supply-and-demand cycles that have occurred repeatedly over the past 100 years and that have affected and will continue to affect our careers.
-
History shows that technology adapts to the economic conditions. What is the optimum technology in a high-price environment is not optimum for a low-price scenario.
-
This work demonstrates that molecular diffusion may be a viable oil-recovery mechanism in fractured reservoirs during injection of carbon dioxide (CO2) for enhanced oil recovery (EOR).
