Built by a working company man
Kill sheets, ECD, bit TFA, pills, circulation strokes and a cement displacement tally: the numbers you work out every hitch, laid out the way you'd figure them on location.
Displacement tally
| BPM | Static | Pipe | Est. psi |
|---|---|---|---|
| 6 | 1,836 | 64 | 2,140 |
| 4 | 1,836 | 32 | 2,028 |
| 2 | 1,836 | 9 | 1,925 |
The tools
Type in your numbers and get the answer. If something's missing, the app tells you exactly which box to fill.
Wait & weight kill sheet built for horizontal wells, kill mud weight, ICP / FCP, MAASP, a pump-down kill tally and a quick kill card.
ECD at the bit with and without cuttings load, annular pressure loss by interval, bit and motor pressure loss, and a quick what-if check.
TFA for any number of jets and mixed sizes, plus the reverse: enter the TFA you want and get the jet sizes to run.
Pump output, surface-to-bit, bottoms up and full-circulation volumes and strokes from your string, BHA and hole sections.
Weighted pill and slug sizing, dry-pipe length, staged pill circulation and FIT / LOT checks that carry your numbers between screens.
Surge and swab against your approved limits, backpressure checks and hole-fill tracking while you trip.
Tap off every 10 bbl tank with pressure and rate, see where the cement is, get the estimated final lift near the end, and copy a clean end-of-job summary.
Air-chamber length, valve depth, pressure below the valve and surface pressure to open, checked against the valve rating.
Set up each well with its string, BHA, hole sections and surveys once. It's saved to your account and on your phone and computer both.
Private to you and saved to your account, so it’s on your phone and computer both.
When a tool is added or improved, it shows up in your app automatically. No downloads, no reinstalling. Your wells and numbers stay exactly as you left them.
Demo
An example well and its cement job, the way they look in the app. Every number is made up, and they all add up to one job.

The real app also has pumps, mud & ECD, surveys, circulation, MPD & pills and well control tabs. Anything missing shows a yellow box that takes you right to the field to fill in.

Shows up under the tank counter once you're close to the bump. Est. psi = static + pipe friction + annulus friction from your last 3 readings.
EXAMPLE 1H – 5½" Production Casing Cement Bumped plug @ 07:59 w/ 264 bbls H2O. Final lift 1,975 psi @ 3 BPM, bumped 500 over to 2,475 psi. Floats held, 2 bbls back. Full returns, 38 bbls cement to surface.
Green boxes are tanks counted, each stamped with the time and rate. The orange strips show where the cement is as you pump. The rate turns orange when it changes.
The casing is on vacuum for the first ~65 bbl (0 psi) while the heavy cement inside falls, then pressure climbs as the cement comes up the annulus.
Example job: gauge 8½" hole, 9⅝" shoe at 8,400 ft, 5½" 20# casing to 12,000 ft (float collar 11,900 ft), landing point 9,650 ft MD at 9,200 ft TVD. 40 bbl spacer, 417 bbl lead at 12.0 ppg, 160 bbl tail at 13.5 ppg, displaced with 8.33 ppg water. 311 bbl of cement is already out the shoe when the plug drops; 38 bbl of lead comes back to surface by the bump.
Sam's Tally Book started as one wellsite supervisor's own app for the rig and the phone. Every tool in it gets used on real wells and checked against the hand math before it ships.

Questions
No. You get the tools and an example well to learn on. Your wells and numbers are yours to enter.
Everything: your wells and well setup, what you type into the tools (kill sheet, hydraulics, cement tally and the rest) and your Tally Book (time breakdown, notes, photos and pulled bits). It's saved to your account and follows you to every phone and computer you sign in on with the same email. Set the well up on the laptop in the trailer and it's on your phone at the cement unit. It also keeps a copy on each device, so it works without signal and uploads when you're back in service. If two devices changed something while offline, they're combined, and the device you're holding wins a clash.
Other users can't see your account or your Tally Book. Morris Consulting only accesses stored information to run, fix or secure the app, or to help when you ask. Details are in the Privacy Policy.
Only what you're allowed to. Well plans, reports and locations usually belong to the operator or company you work for, so follow their rules about confidential information, and check your company's policy before using an AI tool to help set up a well.
Yes, once it's loaded. Open it once with signal or Wi-Fi on each phone or computer, and after that it opens and the calculators and cement tally work with no service, out on the rig floor or at the cement unit. Anything you enter without signal is kept on the phone and uploads by itself when you're back in service. Signing in for the first time and getting updates need a connection.
It runs in your phone's browser. Add it to your home screen and it opens with its own icon, like any other app.
Updates come out to everyone at once. Close and reopen the app to get the newest version. Updates never change or erase your own well data.
Anytime, with one tap in your account. No calls or emails. You keep access until the end of the period you paid for, and yearly plans get a reminder a week before they renew.
It's a reference tool. Check every result against your own math, your rig's official worksheets and your company's procedures. Well control screens never replace your rig's kill sheet.
