If HAL has the $, they could stick it to SLB by buying CLB and my understanding of CLB’s operational model would fit better w HAL. Baker would b smart to buy CLB but I don’t know if they have the $. SLB would destroy any value from CLB.
I don’t think the service industry will be recovering anytime soon so any purchase would have to b done by someone who doesn’t crimp whatever cash CLB generates.
There r some small analytical service companies, eg Von Gonten, that might b cutting into CLB’s biz. I don’t know if the pack of small companies pose a long term threat to CLB’s position and any buyout vig.
