Carbon dioxide (CO2) injection has been widely used in conventional reservoirs for
enhanced oil recovery and CO2 sequestration. Nevertheless, the effectiveness of CO2 …

This research fills the gap in understanding the impact of corrosion inhibitors (CIs) and a
chelating agent on the rheology and stability of foam under harsh conditions. In this regard …

Unconventional hydrocarbon resources mostly found in highly stressed, overpressured, and
deep formations, where the rock strength and integrity are very high. When fracturing these …

Current oil prices and global financial situations underline the need for the best engineering
practices to recover remaining oil from unconventional hydrocarbon reservoirs. These …

A full petrographic and petrophysical characterization of tight sandstones has been
conducted as part of ongoing study of Carbon Dioxide Enhanced Oil and Gas Recovery (CO …

Unconventional reservoirs are characterized by their extremely low permeabilities
surrounded by huge in-situ stresses. Hydraulic fracturing is a most commonly used …

Unconventional oil reservoirs are usually classified by extremely low porosity and
