This is the course web page for Professor Bruce Railsback's GEOL 4320/6320 Petroleum Geology course at the University of Georgia.  The page is an outlet for course news and provides links to course materials.  This page was last updated on Thursday, November 18, 2015, to add news about Exam II.

Course news:

The GEOL 4320/6320 exam questions were updated on November 18, 2015, and a new file produced.  There is one new question, Question 47.  On Exam II, students will be responsible for all questions other than Question 40. However, because Questions 15 and 47 each are effectively ten and seven questions, respectively, the total number of questions is effectively fifty-four.  

Lecture Powerpoint files are now available to students via eLCnew and no longer available via links below.

Exercise 7 will be due on Thursday, November 12, 2015, at 3:30:00 pm. Grades for late exercises will undergo a 20% reduction for each calendar day late or part thereof.

Exercise 10 will be due on Tuesday, October 27, 2015, at 3:30:00 pm. Grades for late exercises will undergo a 20% reduction for each calendar day late or part thereof.

The GEOL 4320/6320 exam questions have been updated, and a new file produced.  There are three new questions, Questions 6, 16, and 20.  On Exam I, students will be responsible for Questions 1 to 20.  However, Question 15 is effectively about ten questions, because there are about ten logs that we have covered, so the number of questions in the list is effectively about thirty.
Students should also remember at least 85% of the 100 points will be allocated to the pre-announced questions in the list, but as much as 15% of the 100 points may be allocated to un-announced questions derived from lecture presentations or readings.

Because Monday, September 7, 2015, is a UGA holiday to celebrate the achievements of the organized labor movement, the due date for Exercise 2 has been extended to Thursday, September 10, 2015, at 3:30 pm.

Railsback has been excused from jury duty, and so class will meet as scheduled on Tuesday, September 1, 2015, and Thursday, September 3, 2015.

A syllabus for Fall 2015 is available below. Of the lecture Powerpoint files linked below, those with "√" have been updated for 2015, whereas files with "-" are still those used in 2013.

The first meeting of this class will take place on Tuesday, August 18, 2015, at 3:30 pm in Room 142 GG.
