Osmotic pressure (P osmotic) is an important mechanism for fracturing fluid loss in clay-rich
unconventional reservoirs. Surfactant is often added to the fracturing fluid to control this loss …

Relative permeability is notoriously difficult to measure in the laboratory for low-permeability
rocks with permeability values in the nanodarcy/microdarcy range. The objectives of this …

The growth in productions of liquid hydrocarbons from tight formations (shales) has been
phenomenal in recent years. During the production of liquids (oil and condensate), large …

Low-permeability hydrocarbon resources are currently under commercial development in
North America. However, recovery factors remain low and production rates often decline …

In this paper, we developed a laboratory protocol to evaluate the performance of three
microemulsion (ME) additives in fracturing water for enhanced oil recovery. We applied the …

Relative permeability is an important control on fluid (gas/liquid) mobility in the reservoir,
and a key input for models used to evaluate primary and enhanced oil recovery in tight …

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 …

Technology advancements (eg, hydraulic fracturing and horizontal drilling) to recover
unconventional oil and gas (UOG) resources are critical in maintaining future US oil and gas …

Well deliverability impairment due to liquid dropout inside gas-condensate reservoirs below
dew-point pressure is a common production problem. The operating conditions and the …

Fluid distribution and fluid-rock interactions within the nano-/macro-porous pore network of
tight oil reservoirs will affect both primary and enhanced oil recovery (EOR) processes …
