Depositional environments of the White Rim sandstone member of the Permian Cutler formation, Canyonlands National Park, Utah The White Rim Sandstone Member of the Permian Cutler Formation in Canyonlands National Park, southeastern Utah, was deposited in a coastal eolian environment. The White Rim consists of three types of eolian deposits: dune, interdune, and sabkha. Characteristics of the dune deposits are large-to medium-scale, unidirectional, tabular planar crossbed sets; high-index ripples oriented parallel to the dip direction of the foresets; inverse graded laminations formed by ripple migration; sand-flow toes; and raindrop impressions. Interdune deposits are of two types, erosional and depositional, formed under varying degrees of wetness. Erosional interdune deposits are characterized by thin, coarse sand to granule size, bimodal...

Utah, Fewer tags From outcrop to reservoir simulation model: Workflow and procedures Advances in data capture and computer technology have made possible the collection of three-dimensional, high-resolution, digital geological data from outcrop analogs. This paper presents new methodologies for the acquisition and utilization of three-dimensional information generated by ground-based laser scanning (lidar) of outcrops. A complete workflow is documented—from outcrop selection through data collection, processing and building of virtual outcrops—to geological interpretation and the building of geocellular models using an industry-standard, reservoir-modeling software. Data sets from the Roda Sandstone in the Spanish Pyrenees and the Grabens region of Canyon-lands National Park, Utah, USA, are used...

Experiments reacting supercritical CO2 with natural and synthetic brines in the presence and absence of limestone and plagioclase-rich arkosic sandstone showed that the reaction of CO2-saturated brine with limestone results in compositional, mineralogical, and porosity changes in the aquifer fluid and rock that are dependent on initial brine composition, especially dissolved calcium and sulfate. Experiments reacting CO2-saturated, low-sulfate brine with limestone dissolved...
