Reservoir Characterization of Pennsylvanian Sandstone Reservoirs

Production Analysis of Tight Sandstone Reservoir in Consideration of Stress-Sensitive Permeability

Received: August 22, 2016 Revised: February 07, 2017 Accepted: March 10, 2017 Abstract: Background: Tight sandstone reservoirs play an important role in the oil industry. The permeability of tight sandstone reservoir generally has stronger stress sensitivity than that of conventional reservoir because of the latter’s poor physical properties. However, the production analysis of tight sandstone ...

Numerical Simulation on Open Wellbore Shrinkage and Casing Equivalent Stress in Bedded Salt Rock Stratum

Most salt rock has interbed of mudstone in China. Owing to the enormous difference of mechanical properties between the mudstone interbed and salt rock, the stress-strain and creep behaviors of salt rock are significantly influenced by neighboring mudstone interbed. In order to identify the rules of wellbore shrinkage and casings equivalent stress in bedded salt rock stratum, three-dimensional ...

Oil Displacement by Water in Hauterivian Sandstone Reservoir of Kashkari Oil Field

Abstract—This paper evaluates oil displacement by water in Hauterivian sandstone reservoir of Kashkari oil field in North of Afghanistan. The core samples of this oil field were taken out from well No-21st, and the relative permeability and fractional flow are analyzed. Steady state flow laboratory experiments are performed to empirically obtain the fractional flow curves and relative permeabil...

Reservoir Characterization of Upper Devonian Gordon Sandstone , Jacksonburg , Stringtown Oil Field

The Jacksonburg-Stringtown field was discovered in 1895. It is located on the western flank of the Burchfield syncline, in southeastern Wetzel, eastern Tyler, and northwestern Doddridge counties, West Virginia. Over 500 wells were drilled in the field between 1 897 and 190 1 ; most were plugged by 19 10. Primary recovery has been estimated to lie between 1454 and 1590 barrels of oil per acre. P...
