A drilling rig. The traveling block hangs from the crown, and the drill string runs down the wellbore to the bit.

Every metre, measured.

Instrumentation and MWD/LWD systems that measure and log drilling data, from the rig floor to the bit.

Depth Tracker

A standalone, plug-and-play system built to run 24/7 in harsh drilling environments. It reads the drawworks encoder and hookload sensor, then displays, trends and logs your drilling data in real time, and keeps the history.

Nothing else is needed to run it. The Remote Unit on the rig sends data over its own wireless network, or a cable, to a laptop, tablet or touchscreen PC on the rig floor, in the doghouse or in the rig office, and you can add more stations.

The Depth Tracker kit on a table: the yellow Remote Unit case with AC power, slips, hookload and encoder connectors, a black host case with a built-in touchscreen, the hookload sensor, the drawworks encoder, and sensor cables with blue connectors.

How the Depth Tracker works

The Remote Unit sits on the rig floor, as close as 10 feet from the rotary table, and reads the sensors. It sends the data over long-range wireless or a cable to one or more host stations on the rig floor, in the doghouse or in the rig office, which display, trend and log it.

Host Unit

Operator stations, for the rig floor, doghouse or rig office

Rigmatic Telemetry

New release

MWD/LWD software for the rig and the office: gamma, surveys, drilling dynamics and alarms. It takes in data from the downhole tool’s decoder and the rig’s EDR, puts every reading at the right depth and shows it live. Then it produces the log, the reports and the LAS files the client is paying for.

It is one Windows program. There is no server to set up: the data pipeline runs inside the window you are looking at.

  1. Takes it in

    From the MWD decoder, the rig’s EDR, a WITSML store or a captured file, over serial, TCP or UDP, as WITS0, JSON or CSV.

  2. Puts it at depth

    Readings arrive with a time; the log needs a depth. Sensor offsets come from the tool string you build, not a number you type.

  3. Shows it

    Live dashboards, the gamma log, surveys, the wellbore in 3D and alarms, plus a full-screen display for the rig floor.

  4. Delivers it

    The printed log, the reports, LAS and CSV files and the end-of-well package, on your company’s letterhead.

See when the hole leaves the plan

Import the directional company’s plan from CSV, text or Excel. Every survey station then shows how far the hole is from it, high or low and left or right, and the page gives a verdict with the tolerance beside it: in window, off plan, or past the end of the plan.

  • Minimum curvature from every station, recalculated when any station is edited
  • Surveys filed at the directional sensor’s depth, not the bit’s
  • A survey report with plan view and vertical section at equal scale

The hole rises above the dashed plan line after the landing point and stays above it out to the bit at 3,600 m MD.Trajectory tab looking straight down, zoomed in on the lateral. The hole runs south-east beside the dashed plan line, to its right, and the gap widens toward the bit at 3,600 m MD.Surveys tab with the station table from 2,940 to 3,330 m MD: inclination, azimuth, TVD, dogleg, position and distance from plan on each row, with red markers on rows off plan. The panel on the left reads Out of window: at 3,600 m the hole is 3.19 m high of plan and 124.36 m right, against a window of ±3.00 m TVD and ±5.00 m lateral.Trajectory tab, the whole well seen from the side. The hole, in teal with a circle at each station, drops vertically, builds angle and turns into a horizontal lateral ending at 3,600 m MD and 1,893.7 m TVD. The dashed plan runs just below the end of the lateral.

Shock, stick-slip, downhole RPM, pressure and temperature, against the limits you set.

Alarms

Part of the alarms page: limits for downhole temperature, lateral shock and stick-slip, all in limits, and this bit run’s breaches: warning and critical lateral shock and a stick-slip warning, each with the worst reading, its depth, the time and how long it lasted.
Warning and critical limits per channel, with a deadband and a minimum duration, and every breach on the run.

Reports

First sheet of a daily drilling report on a service company’s letterhead: well details, then the period with depth at start 2,764.3 m, depth at end 3,421.9 m, footage 657.6 m, 17 h 11 m on bottom and average ROP 38.3 m/hr, the bit run, formation picks and the surveys taken.

Contents page of an end-of-well package: operator, service company, rig, job number, 3 bit runs and 99 survey stations, then a linked list of the daily drilling reports, bit run summaries, survey report, tool performance report, data appendix, log print and LAS files.
Each report is saved as PDF, HTML or CSV, on your letterhead. The end-of-well package links them all from one contents page.

It does not guess

  • A job will not start on a feed that has never delivered a byte.
  • Gaps in the telemetry are drawn as gaps, not as straight lines.
  • A stale value is held back from the EDR, not repeated as current.
  • No alarm limits ship with it. The ones you set are the only ones it uses.

Everything in one program

Set up and support

  • The well, its bit runs, the tool string and the depth references
  • Every incoming connection, with its uptime and last frame
  • Units, the alarm sound, and backups to a folder you choose
  • Raw packets as they arrive, and a recording of the session for support

Watch

  • Live readings as tiles, in a standard layout or your own
  • A full-screen display for a second monitor on the rig floor
  • Warning and critical limits, an alarm sound, and every breach
  • Shock, stick-slip, pressure and temperature: what the tool has been through

What comes out

The log and the paperwork are what the client pays for. Every document in a package is built from one snapshot of the job, so no two can disagree about the depth of the well.

LAS
LAS 2.0, one file per bit run, with any corrections listed in the file
PDF
The log at a true 1:200, 1:500 or 1:1000, and every report. You see the sheet count before you print.
CSV
Each bit run, and a data appendix with one file per table
JSON
The logged curves, with the run’s survey stations
WITSML
Log and trajectory documents, written to a folder
WITS
Gamma, surveys and toolface sent live to the rig’s EDR, so they reach the company man’s screen

The end-of-well package is a folder, not a zip: a contents page linking every report, the log print and the LAS files, ready for a memory stick or an email.

BHA Data Logger

A self-contained logger that runs in the bottom hole assembly and records torque and weight on bit, time-stamped, through the whole run. Nothing is connected at surface while it is in the hole.

Set it up from a Windows PC before the run. When the tool comes out, connect it again and download the run as a CSV.

Records
Torque and weight on bit, with date and time
Interval
1 s by default; 5 s, 10 s or 60 s for long runs
Logs when
Torque or WOB passes the threshold you set, so near-zero noise stays out of the file
Storage
SD card. A 200-hour run at 1 s is about 720,000 rows, roughly 25 MB.
Power loss
Keeps its calibration, thresholds and active job file
Software
One Windows program, nothing to install. Works offline once activated.
BHA Data Logger software, not yet connected: a connection panel with port, Sync RTC and Flash Firmware buttons, a live readout for date, time, torque, WOB and temperature with a 1 s interval, torque and WOB thresholds, separate calibration for torque and WOB, a file manager showing the active log LOG.CSV, and an empty session log table.
The logger software, waiting for a tool to connect.

Before the run

  1. Sync the logger’s clock to the PC with one click.
  2. Zero both sensors, then calibrate torque and WOB against a known mass.
  3. Set the logging thresholds and interval.
  4. Start a new job file for the run.

After the run

  1. Connect the logger over USB.
  2. Download the run as a CSV.
  3. Open it in Excel or your own analysis tools.
