2018 is history. Leave any comments (and suggestions for blog, Guidebook, and Guidebook Companion improvements) in the comments below. I would enjoy hearing from anyone and everyone.
Please remember the blog rule: prior PE Exam questions, in whole or in part, will NOT be discussed on this blog. General topics, such as resources, testing techniques, or general problems only!
UPDATE: PLEASE remember the blog rule!!! I'm having to delete entire comments below (much with good commentary) because they "cross the line" into problem discussion.
For example, comments like: "several of the...questions
with probability” is crossing the line (as I've just been informed by a person who decides where that "line" is).
Come on folk; I'm going to start moderating comments before they post to respect the integrity of the test. Or just remove these type of posts (or even the blog) altogether. Let's help everyone out here so people can have a free resource to study from (as well as become better engineers).
One more clarification: if your comment got deleted, please note I'm NOT claiming it was improper; I'm sure I nuked a lot of good, legit comments that were mixed into other comments. I'm just trying to be very conservative and fast at the same time.

Separator: 2016 #59
Problem 59. A 24 inch dia horizontal separator designed for 1M STB OPD...liquid retention rate is 1.1 minutes with a desired operating level of 40%. The manufactured seam-to-seam length: (A) 3 ft; (B) 5 ft;
(C) 7 ft; (D) 9 ft.
This is merely the Guidebook example. Le in this case is 3.4 ft. Next one decides if gas or liq dominates and do the second calc for 5.4 ft. Knowing separtors must be 5 ft min and rounding up by 2.5 ft, seam-to-seam length is 7.5. Nearest answer? (C).

Cement: 2005 #73 (similar)
Time for a simple cement calculation problem. Using random numbers:
16" 65 lbm/ft casing set to 2,000 ft in 20" hole (float collar 100 ft above float shoe).
Use cement with a yield of 1.32 cf/sack. Slurry sacks w/ 5% excess?
Use the Redbook for 20/16 hole/casing for 0.7854 cf/ft.
Annulus cf: 0.7854 cf/ft(1.05 excess)2,000 ft = 1,649 cf.
1.2684 cf/ft(100 ft) = 127 cf.
Total = 1,776 cf/1.32 cf/sack = 1,346 sacks (round up).
Note that if using a log to locate surface water for regulatory reasons any water signature on the resistivity curve must be considered "water" (to be conservative). For example, if there was a dip in resistivity in a 1,500 to 1,550 sand, you would have to use 1,550 ft as the lower boundary of the sand.

Underbalanced Drilling: 2018 #68
Problem 68: The following statement about underbalanced drilling most FALSE is:
(A) During the workover...a suspension plug is installed...after the well is lubricated to kill fluid.
(B) Advantages include eliminating differential sticking & faster ROP.
(C) Disadvantages include possible increased torque & drag & poor MWD compatibility.
(D) Flow control, not pressure control, is the main well control issue.
This problem is referenced on GB 2 DRL 11 or on HS2 P556, P522, P522, and P520. Note the Guidebook should have the suspension plug step listed before the kill fluid; please pencil this in (fixed in V3).
Note these type of questions could come from any direction; for more detailed information on the read HS P556 (it's quite interesting). Note there are a million ways this problem can be worded; the Guidebook can only introduce and guide you to the subject. You may need to dig deeper using the listed references.

Theoretical Critical WOB: 2018 #47
Problem 47. A BHA has 200 ft of 7 ½ in. by 2 ½ in. steel DC and a 12 ¼ in. bit w/an offset of 3 degrees. The entire hole section has a steady 9-degree inclination and is filled with 12 lbm/gal mud. Once the DC are in full compression, the additional WOB (Mlbm) required to reach the theoretical critical WOB is closest to:
(A) 83
(B) 81
(C) 79
(D) 77.
This problem can be solved using 2 DRL 6 or TS 12 (P593-594). In fact, the problem is similar to the TS12 problem but it has a 5-degrees inclination. Using the calculated 104,790 with a buoyant 108.6 lb/ft(cos9)200ft = 21,453 we can find the delta: 83,266 lbm or (A).
UPDATE: Note for this problem you need to calculate I, w_bp, and m. These calculations are shown on TS12 P593. Two points: 1) have TS12 and be able to navigate it; 2) maybe 80% of what you need from TS12 is in the GB...but TS12 is 700 pages so to be at the top of your game you should have TS12 and know it well. Also anticipate test-writers to "piggy-back" on existing TS problems like this where you can save time if you have seen it before. That's why I wrote this problem the way I did. The real exam is NOT easy; anticipate this level of difficulty (at times). I would expect to lose >3/4 of engineers on this one.

2018 #2 Guidebook available
UPDATE 4: Today is 10/9/2018 and I'm nearly out of new books; to get one in time for the exam you will need to use Amazon.
UPDATE 3: The exam is in October; make sure your postage is fast enough to reach you in time!
UPDATE 2: Note as of 10/19/2018, I've sent out 6 and have at least 10 left so don't hesitate to send your old copy in.
UPDATE 1: Note the new paperback edition has "2018/#2" on the cover and different order to the TOC, so that's how you know you have the update.
The 2018 #2 Guidebook (2nd printing, Sep. 2018) replaces the 2018 #1 (1st printing, May 2018) for all Amazon orders as of 9/5.
This new version supports the Kindle Petroleum PE Problems: 2018 1-40 & 41-80 (that is, Guidebook Companion #5 & #6) for 80 new problems and 8 hours of study. New subjects are now added, such as MOC/PSM/emissions/recovery/stimulation/geology/etc/etc...
The 2018 Companion #6 (Problems 41-80) is available on Amazon. Since this is a Kindle book you can use it instantaneously upon download. As usual, I'll post solutions and answer any questions on this blog.
I'll also exchange older Guidebooks, even spiral versions (non plagiarized only). For those who don't want to give up their current copy due to the risk of shipping time, loss of personal notes, etc., I can work with this, *see the instructions below.
EXCHANGE RULES: Mail to MDD at: 2460 Belmont Dr., Anchorage, AK 99517 the following:
1. Self-addressed, USPS stamped 9x12 envelope (no UPS or FedX).
2. Old Guidebook (*or just include the front & back covers, copyright plus few odd pages).
3. Where you bought it/order number.
4. Toss in $5 cash (no checks) to cover printing expenses.
5. No guarantees. I'll try and return a new copy ASAP but on a first-come, first serve basis as supplies last. For fast & guaranteed, use Amazon.
My entire purpose has always been to help other engineers (via blog, Guidebook, and Companion problems) and merely to break even money-wise. I hope to continue this tradition as time and funds allow. And I'm always available by gmail (mdavidgo) or this blog (use a recent comment section) for any questions or comments.
