CO2 huff-n-puff experimentation and numerical simulation for 3D printed rock samples

International Journal of Heat and Mass Transfer, 2021
Abstract 3D printed rock samples advance the experimental research of fluid flow physics in the petroleum industry. 3D printed replicas can be flexibly tailored to different experimental setups, in addition to the low cost of creation with uniform materials.

Geochemical insights for CO2 huff-n-puff process in shale oil reservoirs

Journal of Molecular Liquids, 2020
Abstract CO2 huff-n-puff process appears to be important to unlock hydrocarbon resources from shale oil reservoirs after multi-stage hydraulic fracturing. While existing literature shows that CO2 diffusion plays a significant role in kinetics of oil recovery, few studies have been able to draw on any systematic research into fluid-shale interaction ...

Evaluation of a Vietnam Offshore CO2 Huff "n" Puff Test

SPE Improved Oil Recovery Symposium, 2012
AbstractFirst CO2-EOR application to the offshore oil field in Vietnam has been investigated through an international joint study scheme between Japan and Vietnam since 2007 and a preliminary study outcome indicated feasibility to some extent. To reduce and mitigate uncertainties/risks in the field scale EOR implementation, a CO2-EOR pilot test was ...

CO2 Huff-n-Puff: Initial Results from a Waterflood SSC Reservoir

Proceedings of Permian Basin Oil and Gas Recovery Conference, 1996
Abstract The application of cyclic CO2, often referred to as the CO2 Huff-n-Puff (H-n-P) process, may find its niche in the maturing waterfloods of the Permian Basin. Coupling the CO2 H-n-P process to miscible flooding applications could provide the needed revenue to sufficiently mitigate near-term negative cash flow concerns in these ...

Performance Evaluation of CO2 Huff-n-puff Processes in Tight Oil Formations

SPE Unconventional Resources Conference Canada, 2013
AbstractTechniques have been developed to experimentally and numerically evaluate performance of CO2 huff-n-puff processes for unlocking resources from tight oil formations. Experimentally, core samples collected from a tight formation with a permeability range of 0.27-0.83 mD are used to conduct a series of coreflooding experiments. The performance of

Enhanced heavy oil recovery via surfactant-assisted CO2 huff-n-puff processes

Journal of Petroleum Science and Engineering, 2017
Abstract CO 2 huff-n-puff suffers from sharp decrease of recovery factor (RF) after the second cycle. The major objective of this paper was to study the key parameter and mechanism of surfactant-assisted CO 2 huff-n-puff process (SACHP) as an enhanced oil recovery (EOR) method after the second cycle.

CO2 huff-n-puff process to enhance heavy oil recovery and CO2 storage: An integration study

Energy, 2022
Abstract In this study, experimental and mathematical studies were carried out to investigate heavy oil production performance using the carbon dioxide (CO2) huff-n-puff process, as well as the potential of CO2 storage in abundant reservoirs. Five experiments were conducted under different injection pressures and different pressure depletion rates ...

Boosting Oil Recovery in Naturally Fractured Shale Using CO2 Huff-n-Puff

SPE Argentina Exploration and Production of Unconventional Resources Symposium, 2018
Abstract Although hydraulic fracturing in Liquid-Rich Unconventional Reservoirs (LUR) have become a norm, the recovery factor continues to be low. Use of Enhanced Oil Recovery (EOR) techniques in LUR have recently become more popular to improve the recovery.

Performance evaluation of CO2 Huff-n-Puff and continuous CO2 injection in tight oil reservoirs

Energy, 2017
Abstract The CO 2 -enhanced oil recovery (EOR) effectiveness was simulated and analyzed by comparing Huff-n-Puff and continuous injection scenarios. A field-scale numerical compositional reservoir model was built based on typical fluid, reservoir, and fracture properties from the Middle Bakken Formation. The effect of matrix permeability ranging from

Removal of Gas-Condensate by CO2 Huff-n-Puff Injection: A Simulation Study

Abu Dhabi International Petroleum Exhibition & Conference, 2017
Abstract Accumulation of gas-condensates in near wellbore regions, and consequently reduction of gas production rates, is a well-known phenomenon in most gas reservoirs all around the globe. In this study, injection of CO2 in "huff-n-puff" mode and its potential advantages of removing accumulated gas-condensates are thoroughly ...
