Geology
Good morning. I trust you all had an enjoyable Homecoming. If not, lie to me. I'm in a much better mood today. *smiles pleasantly* Coffee and snacks are near the back, next to the handouts and please remember to sign the roll sheet.
Today we will be discussing how geology relates to mining and other geologically based professions. To a lesser extent, we will also examine how weathering can affect urban development, and why it's never a truly bright idea to build a house on a mountainside without proper preparations.
Developing rules to predict the reservoir properties of deep-water sandstone sheet systems is important. Sheet sandstone reservoirs are difficult to image and seismic commonly yields an over-simplistic view of reservoir architecture. Distal sands that comprise these reservoirs record longitudinal flow transformations that produce facies changes within thin beds that affect property distributions. Complex bed stacking affects the connected reservoir volume. Downstream channel branching within a distributive network progressively decreases channel depth and aerially equilibrates sand volumes producing “seismic sheet” geometries. Sandstone beds onlapping seafloor topography thin and show facies and lithology changes at pinch outs below seismic resolution. Because sheet sandstones dominate outer fan reaches, these reservoirs generally occur in high-cost, ultra-deepwater settings where data is sparse and models are most dependent on rule-based analog information.
