... Production of viscous oil suffers from low recovery efficiencies owing to the poor mobility ratio. Increasing the amount of water injection and reducing the well spacing improves oil recovery by waterflooding from such reservoirs ( Beliveau 2009 ). Chemical Enhanced Oil Recovery (EOR) can be used...

... recovery in pilot areas by improving vertical and area sweep efficiency. The additional recovery factor gain from the pilot was approximately 10% based on the STOIIP of the polymer-affected area. A significant water cut reduction of 20% was also observed within 6 months of injection. Additionally...

... Abstract The prevalence of longer extended-reach drilling (ERD) wells as a means of more efficiently recovering reserves in a variety of upstream oil and gas applications has led to heightened focus on overcoming related drilling and casing running challenges. The case study presented...

What if the shale drillers of America were sent to work with a geothermal drilling team in Romania? Would they be able to navigate a dangerous and life-threatening event, or would...

...-based fluids is a common technique to improve horizontal downhole cleaning. However, these fluids cannot always guarantee an efficient wellbore cleanout. One way to enhance cleanout efficiency is by rotating the drill pipe to mitigate the settling of solids and facilitate their removal. However, drill...
