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.
-
Secondary and tertiary efforts are critical for sustaining the productive lives of unconventional plays. -
This paper discusses the effect of injected-polymer viscosity on various aspects of a project, from recovery to surface facilities, including both theoretical arguments and practical field experience—which do not always align.
-
This study leverages oil-fingerprinting technology and geochemical data to evaluate the fluid connectivity between a main field and its stepout wells.
-
This paper provides details of a pilot study conducted on multiple wells, showcasing the potential of a novel biotechnology in Bakken enhanced oil recovery.
-
In this work, microseismic observations are integrated with strain and other observations to investigate the microseismic response in relation to the underlying hydraulic fracture geometry for different rock types.

This year’s Acidizing feature presents three SPE conference papers that discuss an important battlefront of enhanced production—carbonate reservoirs, those plays whose heterogeneity, reactivity, and flow behavior pose challenges that remain comparatively little-understood, despite the industry’s intensified efforts to maximize their output.
-
The three papers selected for this feature highlight some creative solutions that aim to increase project value by either increasing recovery or optimizing injectant cost, or both.
-
This paper extends an integrated two-scale continuum model that contemplates mass, momentum, and energy changes to study the acid-stimulation process in complex carbonate acid-stimulation systems with the development of fracture and vug networks.
-
The authors of this paper write that autonomous outflow-control devices can positively affect matrix acidizing by providing the best possible conformance.
-
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.
