Cyclic gas injection effectively enhances oil recovery for low-permeability oil reservoirs.
Numerous theoretical, mathematical, and laboratory investigations have attempted to unlock …

Shale and tight oil reservoirs, with horizontal wells and hydraulic fractures, typically have a
recovery ratio of around 10%. The exploration of tight oil and shale in North America has …

The significant amount of gas produced from unconventional reservoirs in the US in recent
years has reduced market prices for hydrocarbon gas and created an opportunity for using …

Injection pressure, soaking duration, and depletion strategy are crucial operational
parameters for a successful gas Huff-n-Puff (HnP) pilot. There is limited experimental data …

In this paper, we propose a novel analytical solution to predict the diffusion coefficient and
depth of natural gas penetration during soaking period of the cyclic gas injection process …

Hydrogen can be a critical part of the energy transition and salt caverns have been
considered for underground hydrogen storage. Although there have been some successful …

Gas injection for enhanced oil and gas reservoir recovery is a crucial method in offshore
Carbon Capture, Utilization, and Storage (CCUS). The B6 buried hill condensate gas …

Huff-n-Puff technology is considered one of the most effective methods to increase oil
recovery in shale reservoirs. Previous works were mainly focused on Bakken and Eagle …

Recent field reports show the uplift in oil production rate (qo), after the shut-in period,
referred to as “flush production”. The conventional hypotheses for explaining this …

Abstract Gas Huff-n-Puff (HnP) has been implemented as an enhanced oil recovery
technique to recover the residual oil after primary production from unconventional wells …
