Your net pay numbers are stuck behind a seat you don’t have
The LAS is already on your laptop. The cutoffs are already in your head. What’s missing is the one thing that turns them into net sand, net pay, net-to-gross, phi-h and HCPV, without booking time on somebody else’s Techlog licence or rebuilding the spreadsheet from scratch at 11pm.

LAS 2.0 unwrapped ASCII or a delimited export. Porosity, Vsh and Sw come in as curves from the file, so there is no column of readings to retype.
Your cutoffs, not ours
You type the porosity, Vsh and Sw cutoffs and the interval. Nothing is a recommended value, and the tool never tells you what the rock is worth.
Nulls honoured, units stated
The LAS NULL from ~WELL is excluded from the integration rather than counted as zero, and the depth unit it used is on screen.
Sensitivity in one look
Each cutoff stepped on its own, so you can see how far your own choices move net-to-gross before you commit to them.
