Subject:2016 Course Examination [Blasingame]
Course:Petroleum Engineering 620 — Fluid Flow in Petroleum Reservoirs
Assigned:Mon 24 Oct 2016
Due:Wed 07 Dec 2016 [by 5:00 p.m. (i.e., 16:59:59 US CST)]
P620_16C Students-
The course exam has been mounted on my website at:
General Comments:
●I know this has been a long time in the making, my apologies, I always try to balance the exam with selected "course material" problems and an original problem or 2, but this exam was particularly challenging.
●Please print yourself a working copy of the exam and read through very carefully. I have tried to highlight tasks which are absolutely required.
●You should also print yourself a working copy of this document.
Guidance on the Submission of Your Exam:
●Due date:Wednesday 07 December 2016 [by 5:00 p.m. (i.e., 16:59:59 US CST)]
●Submission:Submit as a SINGLE .pdf file named: P620_16C_CourseExam_LASTNAME_Firstname.pdf
●Document:Document scanning must be in color using at least 300 dpi resolution — NO PHOTOS ARE ALLOWED.
●Recipient:Send to
Requirements:
●Value: In order to be considered for an "A" grade, all 8 problems must be fully worked.
●For a "B" grade you must complete the following problems:
—[Est. 1 day]Problem 1:(10 pts)Mathematical Identities
—[Est. < 1 day]Problem 2:(10 pts)Derivation — Variable-Rate Variable-Pressure Drop Convolution Formulas
—[Est. 2 days]Problem 3:(10 pts)Derivation of Radial Flow Solutions
—[Est. < 1 day]Problem 4:(10 pts)Pressure-Squared Relation for Gas Well Deliverability Analysis
—[Est. < 1 day]Problem 5:(10 pts)Warren and Root Solutions for Dual Porosity Reservoirs
(Hint: All of the "B" problems (with the exception of a couple of components of Problem 1) are in the course notes or in the required text materials.)
●For an "A" grade you must complete the following ADDITIONAL problems:
—[Est. 1-2 days]Problem 6:(15 pts)Derivation of the Fractured Well Solution by Gringarten-Ramey-Raghavan
—[Est. < 1 day]Problem 7:(15 pts)Derivation of a Rate Relation for Pseudosteady-State Flow (constant dpwf/dt)
—[Est. 2-3 days]Problem 8:(20 pts)Derivation of an Approximate Wellbore Storage Solution
(Hint: Problem 8 does have a solution, but it is VERY tedious, I encourage you to solve this problem last. There is a (much) easier solution for a=0, but if you pursue the a=0 case, there will be penalties (probably half-credit maximum).)
●BONUS problem: (By definition, a bonus problem is optional. If you attempt the bonus problem, you must know that only serious attempts will be given credit — e.g., submitting only an outline or problem description is not sufficient for any credit.)
—[Est. ? days]Bonus:(10 pts)This is to be a "near-original" problem proposed and solved by the student. Anyone who wishes to attempt a bonus problem must propose their problem to the instructor and approval must be granted by the instructor for the proposed bonus problem.
Questions/comments should be directed to me and the grader (Alex Valdes-Perez [).
Please note that I am travelling this week and have relatively low confidence in having consistent internet access (other than my blackberry, which I will remind everyone, works EVERYWHERE!).

P.S.:
●I very strongly encourage everyone to submit a typed version of the exam, handwritten versions will be accepted --- but IF YOUR WORK IS HANDWRITTEN, THEN YOU MUST USE 8.5"x11" LINED PAPER ("loose leaf" paper is required, not torn from something that will jam your scanning device). Also, if your work is handwritten, then you must write in PENCIL, no PENS allowed.
