Field notes
The listed calculators cover several field calculations, from cement sacks and displacement to kill weight and pipe capacities. The page says users can save wellbores so pipe data carries into calculators, and that results can be shared as screenshots; these are product descriptions, not functions verified on the homepage. It also says jobs stay on the phone and offers English or Spanish plus feet or meters.
