Orientation for PETE 648: (specific to 2017)

The offering of PETE 648 in the Spring 2017 term remains a bit of a "rebuild" from the course I taught in the early 2000s — a "rebuild" in the sense that I lost all of my course material for PETE 648 in a computer theft in 2004 (lesson-learned: always keep your files backed-up). Another faculty member taught this course from 2004-2014, and I did continue to teach PETE 324 (the undergraduate version of this course) through 2009. However; PETE 648 is (and should be) of more depth and breadth than PETE 324. You are free to review any/all of my archives on my website (, including those for PETE 324 and PETE 663. The reference materials are generally well-organized and provide the means for self-study, and the assignments are both straightforward and extremely well-documented.

Goals for PETE 648: (specific to 2017)

Familiarity with the background, solutions, assumptions/limitations, diagnostics, and methodology for the analysis and interpretation of pressure transient test data and production data. The successful student will have developed both familiarity and mastery of the course materials and assignments. In particular, the course reading assignments (i.e., the "Reading Portfolio") are a critical component, as also are the assigned problems in the "Homework Portfolio," as these text example problems are essential to understanding the scope of pressure transient testing.

Assignments for PETE 648: (specific to 2017)

(Due 17 Apr 2017) Reading Portfolio [Paper reviews for assigned publications.] (50 papers/20 points) 20 percent

(Due 24 Apr 2017) Homework Portfolio [Problems from Lee, et al text.] (25 problems/50 points) 50 percent

(Due 01 May 2017) Final Examination [Problems taken from literature and field cases.] (6 problems/30 points) 30 percent

Total = 100 percent

Philosophy about Students:

I am a teacher, that role defines my life and my career. I am not the best teacher you will ever have, but I can almost guarantee that I will be the best "motivator" you have ever had. Students always come first with me — BUT, students must pull their own weight, I have zero tolerance for those who exhibit a low effort or "just want to get by." My goals as a teacher are:

● To create materials and exercises that ensure that the student masters the concepts/applications for a given topic.

● To challenge the student to become a creative and independent thinker.

● To provide an understanding of a student/young engineer's responsibilities as a professional (i.e., the work always comes first).

Philosophy about Life:

● Most Appropriate Quote:

Opportunity is missed by most people because it is dressed in overalls and looks like work... (hard work is the only path…)

Thomas A. Edison, American Inventor (1847-1931)

● Important Rules for Life:

— Never own anything that eats while you sleep… — Always work harder than those you work for…

— Never own anything that needs repainting… — If you have to herd cats, then be a rat…

— Never own anything that you can't drive a nail in... — Never say no, and there's no limit to where you can go…

● Orientation — This is graduate school, the (only) person you are competing against is in the mirror.

● Work Quality — My highest commandment is that you submit your best work; and ONLY your best work.

● Focus — This is an essential course in reservoir engineering.

● Timeliness — This material is very straightforward, but there is much to learn — do not underestimate your workload and timing.

● Course Materials — The material will teach itself (… I am just more of a guide/coach), but you must put your full effort into the course.

● Connections — I am here to help; I will answer any/all relevant correspondence within 24 hours (unless I am totally offline).

Practical Points for PETE 648: (specific to 2017)

A few practical points for the Spring 2017 term:

● I am on the SPE Board and have at least 2 travel interruptions that will affect PETE 648 in January and in March.

● There will also be occasions where I am on "family rotation," and may lecture remotely, but in general I will try to lecture in person.

● Software is not permitted for coursework, but I do plan a number of demonstrations of software at/near the end of the term.

Policies and Procedures:

1. Students are expected to attend class every session. Resident (not Distance Learning) students are REQUIRED to attend class every session. Distance Learning students are expected to review lecture materials within 24 hours of the lecture being given. This is not a casual requirement, penalties can and will be assigned for missing class.

2. Policy on Grading

a. All work in this course is graded on the basis of answers only — any partial credit is at the discretion of the instructor.

b. All work requiring calculations shall be properly and completely documented for credit.

c. All grading shall be done by the instructor, or under his direction and supervision, and the decision of the instructor is final.

3. Policy on Re-grading

a. Only in very rare cases will exams be considered for re-grading — partial credit (if any) is not subject to appeal.

b. Work which, while possibly correct, but cannot be followed, will be considered incorrect.

c. Grades assigned to problems in the Homework Portfolio will not be considered for re-grading. (specific to PETE 648)

d. Grades assigned to the Reading Portfolio will not be considered for re-grading. (specific to PETE 648)

e. If re-grading is necessary, the student is to submit a letter to the instructor explaining the situation that requires consideration for re-grading, and the material to be regraded must be attached to this letter. The letter and attached material must be received within one week from the date returned by the instructor.

4. The grade for a late assignment is zero. Late or not, all assignments must be turned in.

5. Each student should review the University Regulations concerning attendance, grades, and scholastic dishonesty. In particular, anyone caught cheating on an examination or collaborating on an assignment where collaboration is not specifically authorized by the instructor will be removed from the class roster and given an F (failure grade) in the course.

Scholastic Dishonesty:

THE STUDENT IS HEREBY WARNED THAT ANY/ALL ACTS OF SCHOLASTIC DISHONESTY WILL RESULT IN AN "F" GRADE FOR ALL ASSIGNMENTS IN THIS COURSE. As a definition, "scholastic dishonesty" will include any or all of the following acts:

● Unauthorized collaborations — you are explicitly forbidden from working together on EXAMINATION(S).

● Using work of others — you are explicitly forbidden from using the work of others — "others" is defined as students in this course, as well as any other person. You are specifically required to perform your own work.

Note: Collaboration is permitted on the "homework portfolio." (specific to PETE 648)

Work Requirements, Work Standard, Student Obligation, E-mail Protocols, Computational Tools, and Course Description

Spring 2017

Work Requirements: (layout/format/etc.)

● You must show ALL work — as appropriate, YOU MUST:

Show all details in your calculations (no skipped steps) — all portions of all analysis relations must be shown.

— Show all units in each calculation.

● Work layout: (as appropriate for a given problem)

— NEATNESS: You will be graded on the neatness of your work.

— LABELS: All work, trends, and features on every plot MUST be appropriately labeled — no exceptions.

Work: All work must be fully labeled and documented — equations, relations, calculations, etc.

Trends: This includes the slope, intercept, and the information used to construct a given trend.

Features: Any description of features/points of interest on a given trend (specific times/pressures, flow regimes, etc.).

— LINES: Use appropriate drafting care in construction of lines, trends, arrows, etc.

— SKETCHING: Take great care in any sketches you create/use in your work.

● Plots/Plotting: (as required)

— SYMBOLS: Use symbols for "data."

— LINES: Use lines to represent models/trends.

— COLORS: Use black for all axes and gridlines. Use primary colors (red, green, blue), (please) avoid pastel colors.

— etc.: Please do NOT use a border or "frame" around your plots.

Work Standard:

Simply put, the expectation of the instructor (Blasingame) is that "perfection is the standard" — in other words, your work will be judged against a perfect standard. If your submission is not your very best work, then don't submit it. You have an OBLIGATION to submit only your very best work.

Student Obligation:

You must prepare your work as instructed above, or you will be assessed grading penalties.
