A New Waterflooding Characteristic Curve for Naturally Fractured Sandstone Reservoirs [PDF]

, 2015
Characteristic curves have found wide applications to analysis and prediction of waterflooding behavior for sandstone reservoirs. Based on the theory of water-oil two-phase flow in dual porous media and taking advantage of the relative permeability curve

Theoretical Modeling of the Impact of Salt Precipitation on CO2 Storage Potential in Fractured Saline Reservoirs [PDF]

, 2020
Deep saline reservoirs have the capacity to hold large volumes of CO2. However, apart from the high brine salinity, which poses an injectivity challenge, a high percentage of saline reservoirs are also fractured.

High-Strength Controllable Resin Plugging Agent and Its Performance Evaluation for Fractured Formation

Gels
Lost circulation is a common and complicated situation in drilling engineering. Serious lost circulation may lead to pressure drop in the well, affect normal drilling operations, and even cause wellbore instability, formation fluid flooding into the ...

The Structural and Diagenetic Coupling Controls the Distribution of Deep Carbonate Rock Reservoirs in the Southern of Tahe Oilfield, Tarim Basin

Geosciences
Deeply buried carbonate successions in China’s Tarim Basin host substantial hydrocarbons. In the southern Tahe Oilfield, Middle–Lower Ordovician limestones show little evidence of subaerial weathering because the Upper Ordovician strata protected them ...

A Geologically Consistent Permeability Model of Fractured Folded Carbonate Reservoirs: Lessons from Outcropping Analogue

, 2013
Presently adopted fracture-related permeability models of large folded reservoirs are simplistic and often unrelated to the geological setting and evolution of the considered structure.
