Nicholas Pieri Introduction The Moab fault is a normal fault that runs 45 km exposing Permian units of the Paradox Basin by up to 960 m (3150 ft) of vertical stratigraphic offset (Doelling , 1988; Foxford et al . , 1996 , 1998) . The area most focused on by geologists for fault study is the central section of the Moab Fault. The central section consists of sandstones and siltstones of the Lower to Middle Jurassic Navajo , Entrada , and Curtis formations in the footwall against Upper Jurassic and Cretaceous shale and sandstone of the Morrison , Cedar Mountain , and Dakota formations in the hanging wall (Figure 2) (Eichhub et al . , 2009) . The focus of this research is based around deformational features of the Moab Fault and how these features affect the porosity of the rock. Rock porosity determines how water and hydrocarbons are transported and stored throughout the rock. As

Unformatted text preview: demand for water oil continues to rise it is crucial to understand the role deformation plays on rock porosity and permeability. Forms of deformation include deformational banding, joints and shear fractures, cementation, and bleaching. Deformational bands which are found everywhere in faulted sandstone along the Moab Fault will be observed and discussed. Joints and shear fractures are found along relays and intersections (Davatzes et al . , 2005). Cementation’s ability to affect permeability, and the degree it affects the Moab Fault will also be discussed through field research conducted by varying geologists. Core samples will be used to determine the helium porosimetry and the percent permeability ....
