Estimation of total reserves in shale/gas and shale/oil reservoirs is challenging but critical.
Different logging tools and core-evaluation procedures are used to address this challenge …

Many naturally occurring porous media contain different types of grains with different
wettabilities, therefore, understanding the effect of wettability heterogeneity on multiphase …

Significant advances have been made in the evaluation of micro-and nano-scale variations
of pore structure in low-permeability (unconventional) reservoirs using imaging techniques …

Wettability affects the occurrence and exploitation of gas and oil in shale matrices; however,
conventional methods for shale wettability evaluation (ie, contact angle testing, imbibition …

Surfactants have been used for decades to enhance the production of hydrocarbons from oil-
bearing subterranean formations. Production improvement is tied to optimization of the …

Recently, significant breakthroughs have been made in exploring northeast China's shale
part of the Q formation. On-site observation reveals that the appearance of oil at the …

Recently, significant breakthroughs have been made in exploring one specific shale oil field,
northeast China. On-site observation reveals that the appearance of oil at the wellhead is …

Abstract Low permeability ('tight') reservoirs have become a viable source of hydrocarbons
in North America because of horizontal drilling and multi-stage hydraulic fracturing. While …

Recently, significant breakthroughs have been made in exploring one specific shale oil field,
northeast China. On-site observation reveals that the appearance of oil at the wellhead is …

Fractures are widely present in the subsurface, often representing primary channels for fluid
flow in low permeability rocks. While fracture surfaces are composed by different minerals …
