... investigated the extent and timing of misaligned well orientations on production. Over 71,000 wells from eight US unconventional plays, such as Bakken, Barnett, Eagle Ford, Haynesville, Marcellus, Granite Wash, and Utica, were analyzed for the misalignments of well horizontals with minimum horizontal stresses...

... Abstract Utica shale is one of the major source rocks in Ohio and extends across much of eastern US. Its organic richness, high content of calcite, and development of extensive organic porosity makes it a perfect unconventional play and has gained the attention of the oil and gas industry...

... relationships, well performance must be normalized with engineering data in order to isolate the impact of geologic attributes on well performance. In this study, a well performance predictive model was created in the Utica from identified key play drivers that combined engineering, geologic, and geophysical...

... displacement. In both clay-rich Utica and carbonate-rich Marcellus shale, we observe that increasing confining stress during fracturing results in significant decreases in fracture permeability ranging over 3 to 4 orders of magnitude. In a clay-rich direct-shear specimen, negligible permeability development...

.... In this study, pore pressure and minimum horizontal stress are assessed in the Utica and Point-Pleasant play using easy-to-acquire data and traditional poro-elastic concepts. The result exposes the existence of significant in-situ stress variations in the play and suggests that changes in kerogen maturity...

... Introduction As the number of wells drilled in the Utica Shale play continues to grow, maximizing well performance by optimizing wellbore orientation, landing point and proper completion strategy are vital to the success of this play. This paper will focus on wellbore orientation. Most...
