So you are saying that HAL has no responsibility if they pumped cement down a deep hole. Not responsible for product supplied? Quality, Quantity, etc of materials is HAL's sole responsibility.....the procedural aspects of the cementing job is a joint responsibility between company and vendor.
How many times have you seen slurries of insufficient density (agreed to in the cement rec prior to job site arrival) actually pumped? More times than i would like to recall....they can be due to product inferiority, mixing of too much / too little water for hydration, improper additives in type and/or quality and/or quantity, etc, etc. These are all solely the responsibilty of HAL. While I and others, as wellsite engineers for the operator, monitor these aspects, they are the sole responsibility of HAL and factors beyond the control of the company man (ie - wrongly calibrated HAL densitometers, liquid rate flowmeters, quality and quantity of base cement and additives, water, etc). The aforementioned DO obscure these critical factors and can only be corrected "after the fact" and hopefully, but not always, prior to completion of the cementing job.
I concede there are other reasons cement may fail that are beyond the control of HAL but they are, as i eluded to prior, of less likelihood. I was merely risking, IMO based upon the data currently discussed on this board and other sources, the likely sources of failure.....again IMO.
