.... However, these different gases showed different performance in both of lab scale and field pilots conducted in shale reservoirs. In this paper, numerical simulation methods of compositional models have been incorporated with LS-LR-DK (logarithmically spaced, locally refined, and dual permeability) models...

... the separate ‘upside-down’ or inverted vertical containment of natural gas, condensate and oil in shale reservoirs. Once vertical containment is demonstrated with data from the Eagle Ford shale in Texas, the research moves to investigating huff and puff gas injection in hydraulic fractured horizontal wells...

... Abstract The objective of this paper is to couple wellbore and surface production facilities models with reservoir simulation for a shale reservoir that contains dry gas, condensate and oil in separate containers. The goal of this integration is to improve liquid recoveries by dry gas injection...

... Abstract Evaluation of enhanced liquid recovery from tight or shale reservoirs is currently of great interest to operators. One reason is the low primary oil recovery of tight/shale reservoirs, which ranges between 5-10% ( Shoaib and Hoffman, 2009 ) even after expensive multi-stage hydraulic...

... Abstract Identification of potential oil flow zones in shale reservoirs has been conducted in the past with the use of an oil saturation index (OSI) determined from Rock-Eval pyrolysis measurements on samples collected at pre-specified depths (partial sampling). This study introduces a new...

... Abstract A novel integrated workflow based on Nuclear Magnetic Resonance (NMR) Factor Analysis (FA) is developed to evaluate organic shale reservoirs. Current organic shale formation evaluation techniques cannot distinguish immobile hydrocarbons from producible hydrocarbons. The new workflow...

It is concluded that the methodology developed in this software will prove valuable and facilitate the petrophysical evaluation of shale and tight formations. well logging shale reservoir transit time log analysis upstream oil & gas log...

... Abstract While light tight oil reservoirs such as found in Bakken and Cardium style plays can be stimulated by fracturing, significant oil production from true shale reservoirs dominated by clay size fraction sediments may not be feasible, even when reservoirs are fractured, if current oil...

... Given this pore complexity and low porosities in organic, gas- or oil-bearing shales, it is no surprise that the permeabilities are correspondingly diminished. Stoneburner 8 in his presentation showed that the matrix permeabilities in Shale reservoirs varies in the range from 10 −14 to 10 −3...
