Desk and Derrick published a “D&D Standard Oil Abbreviator” a number of years ago and I’ve found it to be very handy. I got mine from Abe Books.com for around $5 including shipping, so not a costly but very handy reference. It is small however about 200 pages of oil related abbreviations.
Have use the D&D booklet or over 45 years!
Here is another fantastic one.
There is another online source right here.
Hit “Mineral Help” on the top menu and go to the library.
