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.

As the announcement of carbon sequestration projects becomes the norm, it’s time we look at what we know from a technical angle about how these projects need to be run based on the industry’s experience with enhanced oil recovery. -
This paper summarizes the integrated technical learnings from the successful application of the installation of autonomous outflow control technology in a new long horizontal injector well.
-
This paper describes how a better understanding of the connection between the well and the reservoir through use of fiber-optic sensors can improve reservoir simulation models, decision-making, and well-performance evaluation.
-
In this study, the application of electrical resistance heating on multilateral wells is studied to illustrate the enhanced physical and economic benefits of the method.
-
This paper introduces methods to fully couple reservoir simulation with wellbore flow models in fractured injection wells.
-
The paper presents a model for shale gas production in which CO2 is injected by huff ’n’ puff into a hydraulic fracture surrounded by a shale matrix.

Statistics are important in knowing where the sharp minds of SPE members are investing their energies. Typically, this is also in proportion to what those members need. Hence, it is noteworthy that more than a fifth of the papers were about CO2-based EOR, indicating not only renewed interest but also the motivation for carbon capture, use, and storage.

This study explores pitfalls experienced when using capacitance/resistance modeling as a plug-and-play technique for waterflood optimization and discusses workarounds and mitigations to improve its reliability.

As the discovery rate of new hydrocarbon resources decreases, the need for more-efficient enhanced-oil-recovery processes increases. Unlike in the past, however, when the efficiency was defined in terms of maximizing the recovery factor (RF), the new interpretation of efficiency is based on optimizing the balance between RF and the reduction of carbon footprint.

This paper reveals the potential of an in-situ generated gel system designed with a bionanoparticle that has tunable strength and gelation reversibility in porous media for underground applications.
