A Systematic Approach for Upscaling of the EOR Results from Lab-Scale to Well-Scale in Liquid-Rich Shale Plays

Abstract

Breakthrough technologies such as horizontal drilling and hydraulic fracturing have led to game-changing results in the oil and gas industry. With the increase in energy demand and the overall growth in oil production in the United States, unconventional resources have become extremely attractive to exploit this end. The

A Literature Review of CO2, Natural Gas, and Water-Based Fluids for Enhanced Oil Recovery in Unconventional Reservoirs

“…Numerous short cycles over a specified duration were more beneficial than a single cycle. Akita et al presented an equation to upscale experimental EOR results to field-scale to account for all the unknown parameters in the field (Table , entry 53) . They suggest that the high laboratory oil recoveries are not observed in the field because of the low area of the matrix exposed to EOR fluid in the field.…”

“…Akita et al presented an equation to upscale experimental EOR results to field-scale to account for all the unknown parameters in the field (Table 5, entry 53). 231 They suggest that the high laboratory oil recoveries are not observed in the field because of the low area of the matrix exposed to EOR fluid in the field. The authors noted that oil recovery is dependent upon the Biot number, which is the product of the matrix volume and fracture permeability divided by the product of the fracture surface area and the total gas diffusion coefficient in the matrix.…”
