The demonstration of the proposed methodology was performed by the first author on 10 (ten) separate cases of production from gas wells in the Marcellus Shale (PA...

... Abstract Individual well performance in the Marcellus Shale of northeastern Pennsylvania varies markedly, even in areas where the lithology, fluid composition, and completion design are consistent. A primary reason for this is the natural fracture system, which influences hydraulic fracture...

While previous reports have focused on iron oxides and sulfate mineral scale precipitation in the near-surface matrix alteration zone, our observations show that these reactions account for only...

... Abstract The publicly available multi-terabyte dataset of the Marcellus Shale Energy and Environmental Lab (MSEEL) consortium provides a unique opportunity to develop fracture models and analyze the effectiveness of the stimulation of a reservoir on a consistent base.

We evaluated the geochemistry, microbial community structure, and microbial abundance of produced water samples collected from the Marcellus Shale, Permian Basin...

... Abstract The Middle Devonian Marcellus shale play has emerged as a major world-class hydrocarbon accumulation and represents one of the largest and most prolific shale plays in the world. According to many outcrop studies in the region, natural fractures are well developed in the Marcellus...

... Abstract The highly productive nature of the Marcellus Shale has led to an interesting observation where individual well estimated ultimate recoveries (EURs) often exceed the calculated gas-in-place (GIP). These observations have led us to question our understanding of GIP, vertical...
