Enhanced recovery
Coreflood experiments reveal that alkali significantly reduces viscosity loss in polyacrylamide flooding systems by minimizing adsorption and improving polymer stability under shear stress. The findings position viscosity retention as a key screening criterion for successful alkali-polymer enhanced-oil-recovery applications.
This study investigates the potential for in-situ hydrogen generation from hydrocarbons using in-situ combustion, with particular emphasis on the role of kerogen content and heating mode.
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.

A pilot project validates the use of an advanced polymerflooding technology on the Alaska North Slope. -
Russia’s Gazprom Neft Technologies is partnering with France’s SNF, the world’s largest maker of polyacrylamide, a polymer widely used in Chemical EOR. They aim to develop demand for chemical flooding technologies throughout Siberia.

The complete paper aims to identify the role of different geological settings with different types of fluid saturations in the response of EM-wave propagation and absorption.
-
In the complete paper, the authors generate a model by using an artificial-neural-network (ANN) technique to predict both capillary pressure and relative permeability from resistivity.
-
The complete paper describes the first successful implementation of natural dumpflooding offshore Malaysia as a case study to provide insight into the value of using the approach to maximize oil recovery in a mature field, particularly in a low-margin business climate.
-
The enhanced-oil-recovery literature produced in the past several months was dominated by reservoir modeling and characterization; flood enhancements; machine learning; and, more notably, relative permeability estimation. This last one needs to be understood further.
-
Malaysia’s national oil and company will employ the technology suite in secondary recovery and well stimulation. The deal follows the service provider’s recent agreements in the Middle East.
-
In the complete paper, a philosophy for the future of EOR projects is developed through a series of questions that applies to the industry’s transition from completion of conventional EOR toward unconventional EOR.
-
To reach their targets for carbon neutrality, many oil and gas producers are investing in other energy industries. This US company will instead get there by investing more in its oil fields.
-
The challenge is immense, but the promise is, too. If the oil and gas business can scale up CO2 EOR, then it can play a very big role in mitigating climate change while offering carbon-negative fuels.
