Design of Service packages

Today each of these packages is assembled from a chain of separate spreadsheets and a Word template: one file for choke sizing, another for separator capacity, a third for the flare layout, each carrying its own copy of the constants and its own author's judgement. Nothing checks that the numbers in one agree with the next, and nothing records which version of which assumption was used.

Here the well is described once. The calculations run in dependency order from that single description, every constant is drawn from a register that is owned and versioned rather than typed in, the design limits are checked automatically against the published standards, and the client document is generated from the same numbers that were checked — not retyped into a template afterwards.
