A number of indices generated from SARA analyses data are used for characterization of
petroleum mixtures (eg colloidal instability index I c=(As+ S)/(R+ A) and asphaltene index I …

ABSTRACT The Williston Basin has proven to be a global super basin. Initially, development
across this basin was dominated by conventional production from the Madison Group and …

One of the important challenges of the oil industry is the formation of asphaltene deposits
and emulsions, which cause many operational and economic problems. Asphaltenes are …

Fouling is one of the leading causes of energy loss in oil industry, particularly in preheat
exchangers of refineries and desalting units. For each day that an oil operation unit …

In this paper, a new method called sweet spot index (SSI) is proposed by the combination of
shale oil mobility and shale reservoir fracability to predict the vertical distribution of shale oil …

Tight resources are defined as low porosity (less than 10 pu)-low permeability (nanodarcy–
microdarcy scale) formations, from which natural primary production is minimal and …

As the petroleum industry builds long-term production histories in major liquid-rich
unconventional resource (UCR) plays, development geologists and engineers have realized …

It is difficult to obtain the end-members required to allocate commingled oil samples
produced from a shale reservoir that has been hydraulically fractured–and then use those …

Solvent extracts obtained from center-cut horizontal core plugs selected in the Upper
Wolfcamp (UW) and Eagle Ford source-rock (SR) beds contain unaltered volatile (ie …

Stratum Reservoir has developed a novel method of low temperature hydrous pyrolysis (EZ-
LTHP) to mobilize oil from wet water-based mud (WBM) cuttings. This workflow yields …
