Understanding the Impact of Open-Framework Conglomerates on Water-Oil Displacements: Victor Interval of the Ivishak Reservoir, Prudhoe Bay Field, Alaska [PDF]
, 2014 The Victor Unit of the Ivishak Formation in the Prudhoe Bay Oilfield is characterized by high net-to-gross fluvial sandstones and conglomerates. The highest permeability is found within sets of cross-strata of open-framework conglomerate (OFC).

Journal of Petroleum Exploration and Production Technology, 2018 The main purpose of this work is to prepare an efficient series of preformed particle gels (PPGs) and to study their behaviors to control unwanted water in oil fields. To this end, 12 copolymer samples composed of acrylamide and acrylic acid [poly(AAm-co-

Modelling the adsorption-desorption behavior of CO2 in shales for permanent storage of CO2 and enhanced hydrocarbon extraction [PDF]
, 2017 Increasing global need for energy security has spurred a need for enhanced oil and gas recovery from unconventional reservoirs. From a carbon cycle point of view however, enhanced hydrocarbon extraction results in higher concentrations of CO 2 in the ...

Study on Pulse Characteristic of Produced Crude Composition in CO2 Flooding Pilot Test
Geofluids, 2018 It has been observed in many laboratory tests that the carbon number of the maximum concentration components (CNMCC) of produced oil varies monotonically with CO2 injection volume at the core scale. However, in CO2 flooding pilot test at the field scale,

Experimental study of flow friction behavior in coiled tubing
Energy Reports, 2022 Coiled tubing (CT) technology has been widely applied in well cleanouts, drilling plug, and shale oil and gas fracturing. Fluid flow in CT produce a more significant flow friction pressure loss because of the long length and small tubing diameter coiled ...
