"It looks like they didn't do a wiper trip on mk1 before wireline. Would this have exaberated the hole deterioration problems we were having?"

No mid wireline operation wiper trip programmed for M1 because wireline operations were expected to be much shorter in duration than in M2. Looking at the hole issues and differential sticking issues we had in M1 I think a wiper trip would have been pointless unless they dropped the mud weight at the same time.

"how common is it to do a wiper trip before logging and why do you think they have chosen to this time around?"

This is a mid wireline job wiper trip and it's quite a common practice where there's a prolonged logging program planned and it includes MDTs.
