A paper tally sheet does not add up as you go, does not tell you the joint you just wrote down is four feet short of every other one, and does not tell you where you stand against the setting depth until somebody sits down with a calculator.
| Jt | Length | Cumulative | Vs avg |
|---|---|---|---|
| 5 | 39.71 | 200.08 | −1.0% |
| 6 | 40.44 | 240.52 | +1.1% |
| 7 | 34.60 | 275.12 | −13.7% |
| 8 ● | 40.18 | 315.30 | +2.2% |
| 9 | 39.95 | 355.25 | +1.4% |
| 10 | 40.27 | 395.52 | +2.0% |
Four things a tally sheet and a phone calculator between them cannot do.
Type the measured length, hit enter, and the cumulative figure updates. The next joint number is already filled in for you. Nobody has to add a column of forty numbers under a light at three in the morning, and nobody has to add it a second time to check the first.
Every joint is compared with the average of the joints entered before it. Anything more than 3% off — a pup joint written down as a full one, a transposed tape reading, a joint that never got measured properly — is flagged on the spot, while the joint is still on the floor and can be re-measured.
Record the planned setting or landing depth once. From then on the app carries the difference: how much string is still to go, or how far past the plan the tally has run. If no planned depth has been recorded it says so plainly rather than inventing a number.
One tap produces the field tally sheet: string identity, weight, grade and connection, the joint-by-joint table with cumulative and deviation columns, the totals, the depth comparison, and signature lines. Print it or save it as a PDF for the morning report.
Every casing run and every string built on every rig needs a tally, and it is still overwhelmingly done with a tape, a clipboard and mental arithmetic. The inventory systems that fix it are sold to operators by the seat. This one is nineteen dollars and lives on the phone of the hand actually counting the joints.
Built by Oil Rigs Now for the people on the pipe rack.One purchase, the whole tool, on every device you sign in on.
Buy it once, keep it. There is nothing to renew and nothing to cancel.
Works offline once installed. All data stays on your device — nothing is uploaded anywhere. No refunds. All sales are final.
No. Install it once and it runs entirely on the device, with no connection at any point. Every string and every joint is stored locally.
The data lives on the device, so back it up. The Backup tab exports every string and joint as a single file you can restore on another phone or tablet, and exports the active string as a CSV for a spreadsheet.
No, and it does not pretend to be. It records what was measured and does the arithmetic on it, the same job the paper sheet does. String design, landing depth and the decision to run stay with the Drilling Supervisor under the standard rig procedure.
Yes. It is set per string, so a tight range of new casing and a mixed rack of drill pipe can each carry a sensible threshold.
If you enter a loss per connection it applies it across the connections between joints and reports gross and net length separately. Leave it blank and you get the gross tally only.
