    Oil and gas industry app for lease operator rounds and run tickets

    Gauge sheets on clipboards and readings typed in at the end of the week leave production accounting guessing. Agnotic Technologies builds the offline field app your lease operators use on every round, and the measurement records behind it, so tank gauges, run tickets and seal changes reach allocation complete and on time.

    Industry Overview

    What is an oil and gas field operations app?

    An oil and gas field operations app is the mobile tool lease operators use on daily rounds to record tank gauges, meter readings, run tickets and seal changes, often with no signal. Agnotic Technologies builds it with offline capture, checks on the device and a full edit history, so readings reach production accounting before the allocation cut-off.

    Who uses it

    Who touches a field reading?

    One gauge reading passes through several hands before it becomes a reported volume. The app gives each role the screen and permissions it needs.

    Lease operators and pumpers

    Run the daily route, gauge tanks, read meters and record seal changes, usually on a rugged tablet or phone with patchy coverage.

    Field foremen

    Assign routes, see which stops were missed and approve corrections before they leave the field.

    Production accountants

    Need complete, on-time volumes and tickets for daily allocation and month-end reporting, with a record of every change.

    Purchasers and haulers

    Take the load and sign the run ticket, so their copy and the operator's copy must carry the same numbers.

    Measurement and regulatory staff

    Answer audits on federal, Indian, state and fee leases from the same records the field created.

    Industry Challenges

    Where do field readings go wrong?

    This failure-point list is what we check first when we review an operator's current rounds. Each item is a data problem the app has to prevent, not a training issue.

    • Duplicate readings after offline sync: a round is saved twice on a device that lost signal, or two operators gauge the same tank, and both records post.

    • A tank gauge entered against the wrong tank or the wrong calibration chart, so the observed volume is calculated from another tank's strapping table.

    • A run ticket closed without the numbers of the seals removed and installed, or without S&W and observed gravity, which leaves the sale unsupported.

    • Readings that arrive after the daily or month-end allocation cut-off, so production is allocated on estimates and corrected a month later.

    • Edits made in the office with no record of the original value, who changed it or why.

    • Gauges taken before the tank has settled, or with temperatures missing, so the volume cannot be corrected to standard conditions.

    Our Approach

    How should an operator design field data capture?

    Three design choices decide whether the app helps accounting or just moves the clipboard onto a screen.

    Check at the tank, not in the office

    Required fields, tank and chart selection and range checks run on the device, so a missing seal number is fixed while the operator is still on the pad.

    Make every reading unique before it syncs

    Each reading carries an ID created on the device, plus the round and the tank, so a second sync of the same record updates it instead of creating a duplicate.

    Work to the accounting calendar

    The app shows which readings are due before the daily and month-end cut-offs and flags late ones, so allocation runs on measured volumes.

    Capabilities

    What do we build into an oil and gas field app?

    Modules for lease operators and the production accounting team behind them. Sensor telemetry and HSE inspections are separate builds; this app is for manual measurement.

    Route and round planner

    Each operator's wells, tanks and meters in stop order, with what is due today and what was missed yesterday.

    Tank gauging screens

    Opening and closing gauges, temperatures and samples, with observed volume calculated from each tank's own calibration chart.

    Run ticket capture

    Uniquely numbered tickets with S&W, gravity, seal numbers and signatures, closed only when every required field is present.

    Seal log

    Every seal installed or removed, the valve or meter it sits on, the position it was sealed in and the reason it came off.

    Well and meter readings

    Pressures, meter totals, chemical levels and downtime reasons, entered once per stop.

    Offline sync with conflict rules

    Records queue on the device and sync on reconnect; two readings for the same tank and time go to the foreman instead of both posting.

    Edit history

    Office corrections keep the original value, the new value, who changed it and why.

    Allocation export

    Validated daily volumes and tickets sent to your production accounting system on its schedule.

    Run ticket

    What does a complete tank gauging run ticket hold?

    On federal and Indian leases, BLM lists the fields a tank gauging measurement ticket must carry. We build each one into the app with a check that runs on the device before the ticket can close.

    Tank gauging run ticket fields, why each one matters and the check the app applies

    Measured Impact

    What should field data capture measure?

    Measures we report to the foreman and the production accountant, not to the operator's manager alone.

    Stops visited on schedule

    Wells and tanks visited as planned, and the ones missed.

    Ticket completeness
    Tickets closed with every field

    Run tickets that needed no follow-up from accounting.

    Cut-off hits
    Readings in before allocation

    Readings received before the daily and month-end cut-offs.

    Edit rate
    Office corrections per route

    How often field values are changed later, and why.

    Facts and sources

    Measurement rules the app is built around

    BLM rules for federal and Indian leases. State rules and your own procedures may add more.

    • After oil is measured by tank gauging on a federal or Indian lease, the operator, purchaser or transporter must complete a uniquely numbered measurement ticket, on paper or electronically, with the tank number, opening and closing gauges and temperatures, observed gravity, S&W content and the number of each seal removed and installed.

      Source: 43 CFR 3174.12(a) (eCFR)
    • BLM requires tank gauging at a facility measurement point to follow API MPMS Chapter 18.1 or 18.2, and the tank must be isolated for at least 30 minutes, with its isolating valves closed and sealed, before gauging starts.

      Source: 43 CFR 3174.6(b) (eCFR)
    • For each seal, the operator must keep a record of its unique number and the valve or meter component it is used on, the date it was installed or removed, the position the valve was sealed in and the reason the seal was removed.

      Source: 43 CFR 3173.9(b) (eCFR)
    • The operator's end-of-month inventory records the total observed volume in storage, measured to the nearest half inch, and a gauged inventory must be taken within 3 days either side of the last day of the calendar month.

      Source: 43 CFR 3173.9(a) (eCFR)
    • Records relevant to the quality, quantity and disposition of production from federal leases, including source records, must be kept for seven years after they are generated.

      Source: 43 CFR 3170.7(a) and (c) (eCFR)

    Frequently Asked Questions

    Yes. Rounds, gauges, tickets and seal changes are saved on the device and synced when a connection returns. Each record carries its own ID, so a sync that runs twice updates the record instead of creating a duplicate reading.
