The characterization of heterogeneous fracture patterns in complex reservoirs, such as folds, is difficult, as multiple stages of fracturing and fracture reactivation take place pre-, synand post-folding. Outcrop studies help understand the behavior of fractures and subsequent fluid flow in folds, as outcrops provide both small-scale fracture patterns and the large-scale fold geometry. We aim a...

Joints within the Catskill Delta complex are believed to be natural hydraulic fractures and abundant indirect evidence supports this claim. The indirect evidence is based on many observations of joint surface morphology and joint spacing among other features. The Alleghanian orogeny left a unique imprint on the joint surfaces also, indicating a rotating horizontal compressive stress field. Nume...

In this work, the geochemistry of the rare earth elements (REE) was studied in eleven outcrop samples and six, depth-interval samples of a core from the Marcellus Shale. The REE are classically applied analytes for investigating depositional environments and inferring geochemical processes, making them of interest as potential, naturally occurring indicators of fluid sources as well as indicato...

Due to the increasing amount of photovoltaic (PV)-based power generation being connected to power systems, issues pertaining to the integration of the PV-based generators have attracted intense attention. In this connection, the design of a PV-based stabilizer for enhancing power system dynamic stability is examined. The damping action is achieved through the independent control of real power f...

Fine Dechlorane (DCR) particles with an average size of 12 Am were successfully encapsulated with poly(methyl methacrylate) (PMMA) and poly(1-vinyl-2-pyrrolidone) (PVP) polymers via in situ dispersion polymerization in supercritical carbon dioxide (scCO2). Adjusting the process parameters can control the coating thickness, surface morphology, and degree of particle agglomeration. A uniform thin...

In this paper, a PID fuzzy controller structure is presented. To be successful in implementing fuzzy PID controllers in large applications we must also considered their operating principles. Fuzzy logic controllers are based on empirical control rules. A study case for the validation of the proposed tunning mechanism is presented and analyzed with control application for a synchronous generator...

Unconventional shale-gas plays are formed by fine-grained organic-rich shales of tight-porosity and ultralow permeability which act as the source, seal, and the reservoir rock. The shale-as-reservoir has its beginnings in 1820 but commercial shale-gas wells were drilled in 1990s in Mississippian Barnett Shale of USA by Mitchell Energy after prolonged (about 17 years) experimentations and advanc...
