Daily Drilling Reports (DDR) & IADC Tour Sheet Reporting Console

1. 24-Hour Operations Logging & Official Tour Sheet Standards

The Daily Drilling Report (DDR) (historically known as the Morning Report or IADC Tour Sheet) is the official legal, financial, and operational ledger of all activities occurring on a drilling rig within each 24-hour cycle (typically 00:00–24:00 or 06:00–06:00). Certified by the Company Man (Operator Representative) and Rig Toolpusher (Contractor Superintendent), the DDR documents drilled footage, equipment performance, non-productive time (NPT), fluid rheology, and bit wear.

The WDA DDR Console (accessed directly from the Databases Explorer tree by right-clicking any Channelset and selecting Reports > Daily Drilling Report (DDR)) bridges the gap between manual rig floor reporting and automated sensor analytics. By connecting directly to the well's high-frequency sensor database, WDA automatically computes daily footage, average Rate of Penetration (ROP), and 24-hour statistical metrics (Min, Max, Mean) across all drilling channels while providing flexible manual overrides, standardized IADC activity coding, and multi-format export to Excel, PDF, and WITSML 1.4.1.1 drillReport XML.

2. Automated Sensor KPI Calculation & Manual Override

Instead of requiring rig crews to manually calculate averages from paper charts, WDA scans the high-frequency telemetry in the high-performance database:

• Automated Footage & ROP:

  Calculates daily progress: Footage Drilled = End Depth (24:00) - Start Depth (00:00). Determines true average on-bottom Rate of Penetration (ROP) strictly over active cutting hours.

• 24-Hour Statistical Summary:

  Instantly extracts minimum, maximum, and average values for Weight on Bit (WOB), Surface Torque, Rotary Speed (RPM), Flow Rate, Standpipe Pressure (SPP), Differential Pressure, and Mud Gas.

• Certified Manual Override:

  All automated KPI fields remain fully editable, allowing the superintendent to correct sensor calibration offsets, remove outliers, or input certified values before official sign-off.

3. Standardized IADC 24-Hour Operations & NPT Tracking

The operations log conforms to international International Association of Drilling Contractors (IADC) guidelines:

• Chronological Tour Breakdown:

  Record operational intervals with exact From and To times (hh:mm). WDA automatically calculates decimal duration hours and verifies that total tour hours equal 24.0.

• Standard 4-Letter IADC Activity Codes:

  Classify each interval using standardized codes: DRIL (Rotary/Slide Drilling), CIRC (Circulating & Conditioning), TRIP (Tripping Pipe), BHAS (BHA Handling), CASG (Casing & Cementing), SURV (MWD Surveys), RIGS (Routine Service), and REPR (Unscheduled Repair / NPT).

• Non-Productive Time (NPT) Analysis:

  Flag operations as Productive or NPT. Easily evaluate contractor downtime, equipment failures, and weather delays for contractual billing and post-well operational reviews.

4. Drilling Fluid Rheology & 8-Element Bit Dull Grading

Maintain complete historical logs of drilling mud properties and downhole tool condition:

• Drilling Fluid (Mud) Properties:

  Record Mud Type (WBM, OBM, SBM), Density/Weight (ppg or kg/m³), Marsh Funnel Viscosity (s/qt), Plastic Viscosity (PV, cP), Yield Point (YP, lb/100ft²), and pH for hydrostatic safety and hole cleaning assurance.

• Bit & Hydraulics Record:

  Track bit size, manufacturer, model, serial number, IADC code, nozzle sizes, and Total Flow Area (TFA, sq in) for hydraulic jet impact calculations.

• 8-Element IADC Dull Bit Grading:

  Standardized 8-position syntax when pulling bits out of hole:
  [Inner] [Outer] [Dull] [Location] [Bearing/Seals] [Gauge] [Other Dull] [Reason POOH]
  Example: 1-2-BT-S-X-I-NO-TD accurately codes inner tooth wear (1), outer tooth wear (2), broken teeth (BT), shoulder location (S), sealed bearing (X), in-gauge (I), no secondary wear (NO), pulled for Total Depth (TD).

5. Multi-Format Corporate Publishing & WITSML Export

Export and distribute certified drilling reports across all corporate channels:

• Official Multi-Tab Excel (.xlsx): Generates formatted spreadsheets with custom corporate logos embedded in the header, complete tour sheet tables, and fluid summaries.
• Executive PDF Morning Tour Sheet: Formats printable vector PDF tour sheets ready for morning executive meetings and regulatory archives.
• Standard WITSML 1.4.1.1 drillReport XML: Automatically serializes the entire 24-hour report into Energistics WITSML XML schemas for automated ingestion into enterprise corporate databases and national regulatory portals.
