1 SYLLABUS GEOLOGY 4191/ METHODS IN PETROLEUM GEOLOGY SPRING 2009 Class: TR 1:20-2:35 ESB # 1038 Instructor: Randi Martinsen RANDMART@UWYO.EDU MRRC RM #1012 # Office hrs: TUES-THURS 11am -12:30 pm, or by appointment RECOMENDED CLASS TEXT: Elements of Petroleum Geology, by Richard Selley, 1998 SUPPLEMENTAL CLASS TEXTS: 1) AAPG Development Geology Reference Manual, 2) Applied Subsurface Geological Mapping by Tearpock & Bischke, 3) Basic Well Log Analysis for Geologists by G. Asquith. All are on reserve in the Science Library. Some assigned readings are out of the AAPG Development Geology Manual (cited simply as AAPG), the Applied Subsurface Geological Mapping text (cited as ASGM, and Asquith s book. The assigned readings are to aid you in 1) completing your assignments, and 2) provide additional background information that we may or may not cover in class. How carefully you choose to read them is your decision. Co-requisite/prerequisite: Geol. 4190/5190 (Petroleum Geology) Course Requirements: various exercise/problems There will be no exams in this class. Your grades (S/U) will be based on a series of exercises/homework problems. You will be marked down for exercises turned in late, unless you have a valid excuse (illness, death in the family, etc.). You are encouraged to work together, but you must hand in separate assignments. NEATNESS COUNTS. If I can t read or understand what you do, I can t give you credit for it. You may come to me for assistance during office hours. I am also usually around either the department or IER (Biochemistry rm 311) 9:30 am till 5 pm. Up until the day before the exercise is due (usually the exercises will be due the following week in class, so you have until Friday to meet with me), I will be happy to provide a review of your exercise. In addition to class time, exercises may require an additional 2 to 10 hours/week work outside of class. For each lab you need to bring: Lead pencils Colored pencils Straight edge Scissors Scotch tape
