An AI assistant that turns your WITSML feeds, reports, and offset wells into answers you can act on. Every one traces back to its source.
Ask in plain English, like “why did ROP drop overnight?” You get back an answer that cites the exact reports, channels, and offset wells behind it. Your team checks the evidence, not just the bot.
Fleet Dashboard
Reads the operating record your team already keeps
Drilling teams do not lack data. They lack one operational memory that understands how reports, live streams, vendors, and offset wells explain each other.

A warning appears in one system while the context sits in another.
Engineers spend the first hour reconstructing yesterday instead of deciding today.
Patterns become obvious only after time, cost, or safety margin is already lost.
Less time hunting for context, more time deciding what the rig should do next.
“ROP stepped from 38 to 96 ft/hr at the same WOB and RPM, and MSE dropped with it: a clean drilling break, not a bit problem. It lands within 20 ft of the mud log's projected next top. Loving-2 and Delaware-2 both broke at this same depth and logged a gas show right at the top.”
Field data enters in its native form, gets structured into operational context, and exits as an answer the team can act on.
Connect WITSML feeds, read PDF reports, collect emails, and ingest sensor data.
Clean messy data, structure unstructured text, normalize units, and correlate sources.
Flag activity and trends that diverge from offsets and plan for an engineer to confirm, calibrated per rig during the pilot.
Deliver daily briefs, real-time alerts, and cited answers the team can act on.
Five real screens that turn scattered drilling data into decisions, from the fleet at a glance down to a single connection.
An AI summary of fleet status, your active wells, and the alerts that actually need you, the moment you open the app.
Depth, time, and activity for one well, reconciled into a single brief, with an AI summary you can trace back to its evidence.
ROP, WOB, pressure, and flow on a single time axis, so a slowdown's cause is visible instead of inferred.
The Alerts tab keeps open, acknowledged, and resolved events in one severity-first queue so the urgent item is visible before the next stand.
Upload daily reports or CSVs and TallyBook parses, summarizes, and files them, with the source provenance kept intact.
Instead of opening multiple reports and dashboards to understand why the well is behind schedule, ask TallyBook and review the supporting evidence in the same workflow.
TallyBook connects ROP drops with formation data, drilling parameters, and historical offsets automatically.
It explains what changed, what likely caused it, and the evidence behind it. Flagging the delay is the easy part.
See how the event compares to similar depths, crews, sections, or wells before deciding the next action.
TallyBook · every answer cites its sources
A practical view of file intake, WITSML/ETP, AI modules, private deployment, and security boundaries.
TallyBook brings daily drilling reports, PDF and CSV uploads, email-fed report packages, WITSML/ETP streams, alerts, and offset context into one operational view. In the iOS app, direct upload is currently focused on PDF and CSV files.
Built for operators, drilling engineers, and digital teams who need answers faster, without asking the field to swap tools. Start on one well and keep your current workflow.
