Enhanced recovery
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 a case study from a mature field redevelopment project where pulsed neutron logging was integrated with advanced reservoir modeling to improve the understanding of fluid-contact dynamics and optimize new horizontal well placement.
This paper aims to showcase examples of how integrated analysis of surveillance data in the Azeri-Chirag-Gunashli field has improved reservoir understanding and informed reservoir-management decisions.
-
The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR. -
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.
-
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).
-
In this paper, two different EGR methods are investigated and systematically compared in terms of efficiency.
-
This paper introduces a new carbon dioxide (CO2) -hybrid fracturing-fluid design that intends to improve production from ultratight reservoirs and reduces freshwater usage.
-
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.
-
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.
-
A normal five-spot polymer-flooding pilot has been conducted at the Mangala field, one of the largest onshore fields in India, and results are encouraging
-
Several studies explored the possibility of improving both areal and vertical sweep efficiency in mature water-alternating-gas (WAG) patterns in the Magnus oil field.
-
Foams have proved to be efficient at temporarily blocking high-conductivity layers and improving gas-injection conformance and sweep efficiency in predominantly matrix reservoir systems, at least in laboratory and field pilot tests.
