A Case Study on Simulation of In–Situ CO2 Huff–‘n’–Puff Process

SPE Reservoir Evaluation & Engineering, 2017
In-situ carbon dioxide (CO2) huff-‘n’-puff (ISCHP) is a promising enhanced-oil-recovery (EOR) technique that could overcome some major drawbacks associated with continuous CO2 flooding such as early CO2 breakthrough, high operation costs, and demand for CO2 source. The application in Jiangsu Oil Field triggered the augmentation of well productivity and

CO2 Huff-n-Puff and Storage in Vaca Muerta Shale

SPE Western Regional Meeting
Abstract This study examines the co-application of CO2 huff-n-puff (HnP) technology for enhanced oil recovery (EOR) and sequestration in Vaca Muerta shale rocks. The rock samples undergo a primary production stage to establish a depleted rock sample before conducting CO2 HnP and storage experiments.

Laboratory Evaluation of the CO2 Huff-N-Puff Process for Heavy Oil Reservoirs

Journal of Canadian Petroleum Technology, 1984
Abstract Laboratory tests were carried out to evaluate a CO2 huff-n-puff well stimulation process in a Lloydminster heavy oil reservoir. Two series of phase behaviour measurements were done on the reconstituted oil, each in a pressurization-then-liberation cycle.

Pore-scale investigation of CO2/oil exsolution in CO2 huff-n-puff for enhanced oil recovery

Physics of Fluids, 2020
A pore-scale high-pressure visualization experimental system is used to investigate CO2 exsolution during the CO2 huff-n-puff process for enhanced oil recovery and geological CO2 storage. Eighteen different experimental cases are examined to investigate the mechanisms by which depressurization-induced CO2 exsolution is affected by a near-miscible vs an

The CO2 Huff 'n' Puff Process in a Bottomwater-Drive Reservoir

Journal of Petroleum Technology, 1988
Summary Two CO2 huff ‘n’ puff projects were conducted in the 4,900-ft [1495-m] Reservoir (BA) Sand Unit [4900' R(BA)SUI, Timbalier Bay field, Louisiana. This reservoir is a bottomwater-drive reservoir with a 26 degrees API [0.9-g/CM3] Oil gravity and 18% primary oil recovery. Before CO2 injection, both project wells

Simulation Study of CO2 Huff-n-Puff Process in Bakken Tight Oil Reservoirs

SPE Western North American and Rocky Mountain Joint Meeting, 2014
Abstract Advancements in horizontal drilling with hydraulic fracturing have enabled commercial oil production from Bakken tight oil reservoirs. However, the primary recovery factor remains very low (less than 15%), resulting in the high volume of oil remaining in place.

Scale Prediction During CO2 Huff 'n' Puff Enhanced Recovery, Crooks Gap Field, Wyoming

Proceedings of Low Permeability Reservoirs Symposium, 1991
ABSTRACT Perturbation in the rock-water systems of petroleum reservoirs during CO2 enhanced recovery processes may cause precipitation of scale in production lines. Therefore, a prediction of the scale potential of a particular system is valuable in the design of the enhanced recovery treatments.

Huff-N-Puff Foam Injection in Naturally Fractured Carbonates Using Supercritical CO2

SPE Improved Oil Recovery Conference
Abstract Foam injection into naturally fractured reservoirs unequivocally has superior merits over pure gas injection. In this study, we present a novel foam generation strategy that incorporates the co-injection of surfactant and supercritical CO2 with huff-n-puff technique for the efficient diversion of the foaming gas into the rock ...

A Nanoparticle Assisted CO2 Huff-N-Puff Field Test in the Eagle Ford Shale

SPE Improved Oil Recovery Conference, 2020
Abstract The primary objective of this work was to investigate the results and the possible mechanisms of oil recovery in a huff-n-puff style improved oil recovery (IOR) field pilot using nanoparticle assisted CO2 injection. A secondary objective was to study the sensitivity of the process to injection volume of nanoparticles and gas ...

Simulation study of factors affecting CO2 Huff-n-Puff process in tight oil reservoirs

Journal of Petroleum Science and Engineering, 2018
Abstract CO2 injection is one of the effective enhanced oil recovery (EOR) methods in conventional oil reservoirs, which has been widely applied in the tight oil reservoirs. Although there are some efforts on the investigation of engineering parameters such as fracture half-length, fracture conductivity, and fracture height, the effects of CO2 ...
