Enhanced recovery
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 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.

Numerical simulation methods of compositional models were incorporated with logarithmically spaced, locally refined, and dual-permeability reservoir models and local grid refinement (LGR) of hydraulic-fracture conditions to investigate the feasibility of CO2 injection in shale oil reservoirs. -
In the first paper, a comprehensive experimental evaluation of gas injection for enhanced oil recovery (EOR) in organic-rich shale and, in the second, the effect of fluid transport in organic-rich shale on recovery mechanisms under gas injection.
-
This paper involved laboratory experiments introducing miscible gases into core samples to investigate enhanced oil recovery (EOR) mechanisms for Permian Basin shales to provide information to design field tests for a huff ’n’ puff (HNP) recovery process.
-
In recent years, some effort has been made to use EOR techniques, particularly CO2 injection, to extract additional oil and gas from unconventional resources. This has the potential to change the dynamics (again) of oil production from these tight and difficult reservoirs.
-
One of my best moments is to have made the technical case for polymer flooding and to see the fruits of this several decades later. As is so often the case in our industry, my contribution stands alongside those of many others in the intervening years who have all made the EOR journey possible.

A thermal asset in Oman is characterized by a large-scale steam-drive/cyclic-steam-soak development project, underpinned by extensive data gathering.

This paper discusses an enhanced-oil-recovery (EOR) polymer-flood pilot at the Captain field in the UK North Sea during 2011–2013.
-
This paper discusses the operation of the largest offshore high-pressure water-alternating-gas (WAG) injection pilot using hydrocarbon (HC) gas, with a gas-injection capacity of approximately 100 MMscf/D, in the giant Al-Shaheen field offshore Qatar.
-
There is every reason to believe that enhanced oil recovery through huff-and-puff injections in US tight-oil plays could be a technical success across large numbers of wells. However, widespread economic success remains uncertain.
-
Aker Solutions and FSubsea have agreed to a joint venture, named FASTSubsea, to help operators increase oil recovery.
