Drill Casings

[joro]

I was recently given a drill casing specification by my client that specified H40 7 inch production casing 16 lb/ft and a H40 10.75 inch surface casing 22 lb/ft. However, I have been unable to find any reference to the above mentioned casing. The closest match I have found is 17 lb/ft on the 7" casing and 32 lb/ft on the 10.75" casing.

Does anyone know if the lighter wall casings exist?

Any assistance would be greatly appreciated.

Thanks

A little late but you may want to keep this as a reference.
