Petroleum Well Construction

Summary: Petroleum Well Construction
Review: Excellent in-depth treatment of core processes involved in modern well construction ... these processes are examined theoretically and pragmatically ... and each topic is extensively documented ... very complete and compressed without losing detail ... a great work!

Summary: Some of the formulas are not correct
Review: Page 421 Formula #15-27 Formula #15-27b (?) originally published by Joshi are WRONG! A book that costs more than US$300 should at least be checked for correct equations!
