THREE EXAM QUESTIONS AND ANSWERS PETROLEUM GEOLOGY -MY FIRST QUESTION AND ANSWERS 5) Discuss the different types of traps and seals and the importance of “timing”. Give an example related to the Middle East. “Trap” can be defined as shield against oil and gas movement. In other words, the trap system had been set up before the migration of oil and/or gas to this location. After coming across the trap, oil and

Question 1 The idea of Continental Drift to explain the current shape of Earths landmasses was first proposed by Abraham Ortelius in 1596. He proposed the idea to highlight the geometrical coincidences between America and Europe-Africa. In his work Thesaurus Geographicus he suggested that the Americas were “torn away from Europe and Africa…by earthquakes and floods”, and that “the vestiges of rupture reveal themselves, if someone brings forward a map of the world and considers carefully the coasts

Dolomitization – Question C One of the conundrums of carbonate diagenesis is that seawater is supersaturated in dolomite, yet dolomite is rarely directly precipitated in the present day. Discuss the strengths and weaknesses of different mechanisms that have been postulated to explain dolomitization, and why it is important to understand from a hydrocarbon perspective. Introduction Dolomite (CaMg〖(CO_3)〗_2) is found in carbonate rocks of all ages that formed under a variety of conditions, but today

Introduction to Geology GEOL-101 Midterm 1 Review Based on the textbook: Understanding Earth, 6th Edition, by Grotzinger and Press CH 1: earth system Summary The human creative process, field and lab observations, and experiments help geoscientists formulate testable hypotheses (models) for how the Earth works and its history. A hypothesis is a tentative explanation focusing attention on plausible features and relationships of a working model. If a testable hypothesis is confirmed by a large

Water from the south then flowed in over time, thus forming the evaporites now found along the coastlines there. (Lois Van Wagner, 2013)(Figure 5) However, Wegener believed that only the continents were moving and they plowed through the rocks of the ocean basins. (Colliers Encyclopedia, 1996) Harold Jeffreys then argued

Introduction. Over the past century there have been rapid and noticeable changes in environmental conditions on Earth. These changes can be traced in various geospheres: alterations of the gaseous composition of the atmosphere, major decreases in global ice volume (Cryosphere), in both: land- and water based glaciers with consequent rise of sea-level (Hydrosphere), increase in the frequency and severity of geohazards (Lithosphere) etc. Triggering mechanisms for those changes include both: natural

INTRODUCTION Archie Unleashed is an attempt to put the basic log analysis methodology for computing water saturation into a readable reference document. The beginning log analyst or petrophysicist should have little difficulty with the terms and concepts utilized in this paper, however, most terms are redefined in appendix A. The basic outline of this document closely follows a previous work written for the casual interpeter in log analysis. Archie Unleashed is meant to carry that work one step
