Product Types – Digital Drilling Rig Configurations
We offer digital drilling rigs in four digital maturity levels:
-
Level 1 – Data Ready – Basic sensor package (hookload, torque, RPM, pump pressure). Local HMI with data logging. Manual report generation. No remote connectivity.
-
Level 2 – Connected Rig – Full sensor suite, edge computer, data historian, cloud uplink. Remote monitoring dashboard. Automated daily drilling report. Email/SMS alerts.
-
Level 3 – Optimized Rig – Adds closed‑loop auto‑driller, vibration mitigation, stick‑slip control. Machine learning models for ROP optimization. Integration with MWD/LWD data.
-
Level 4 – Predictive Rig – Adds predictive maintenance models, digital twin simulation, and remote control capability (with local override). AI‑driven stuck pipe prediction.
All levels can be retrofitted to existing SJ Petro rigs or installed on new builds.
Applications – Where Digital Drilling Rigs Deliver Value
-
Multi‑well pad drilling (shale, tight oil, CBM) – The digital rig records every second of the first well. The second well uses that data to optimize parameters, reducing invisible lost time.
-
Offshore platform drilling – Remote monitoring from shore reduces offshore personnel requirements. Real‑time alarm management improves safety.
-
Deep & HP/HT wells – Continuous data surveillance catches warning signs before catastrophic failures. Predictive models reduce NPT.
-
Remote / frontier exploration – Office‑based drilling engineers support the rig without being on site. Data historian ensures no knowledge loss when crews rotate.
-
Fleet operations – Supervisors compare performance across multiple rigs, identify best practices, and standardize high‑performance drilling workflows.

Frequently Asked Questions (FAQ)
Q1: What is the difference between an automated drilling rig and a digital drilling rig?
An automated rig focuses on closed‑loop control (auto‑driller, automated connections). A digital rig adds data acquisition, cloud connectivity, remote monitoring, and analytics. The two are complementary; our digital rigs include automation as the foundation.
Q2: Can I retrofit digital capabilities to my existing rig?
Yes. We offer retrofit digital packages that add sensors, edge computer, HMI, and cloud connectivity to any make of rig. Level 2 (data logging + remote monitoring) is the most common retrofit.
Q3: How much data does a digital drilling rig generate per day?
Typical: 10‑20 GB per day of raw time‑series data (1‑10 Hz sampling). After compression and deduplication, cloud upload is 1‑2 GB per day. The edge computer stores months of data locally.
Q4: Do I need an internet connection to operate the digital rig?
No. The rig operates fully offline; data is stored locally. When a connection becomes available (cellular, satellite, or wired), the system syncs to the cloud. You can also operate without any cloud connectivity – all analytics run on the edge computer.
Q5: Is my drilling data secure?
Yes. Data is encrypted at rest and in transit. The cloud platform uses role‑based access, two‑factor authentication, and is hosted on SOC2‑compliant infrastructure (AWS or Azure). You control who sees what.
Q6: Can your digital platform integrate with third‑party software (e.g., Corva, DrillOps, WellView)?
Yes. We expose a REST API and real‑time OPC‑DA feed. Third‑party applications can subscribe to the data stream or query the historian.
Q7: What kind of reports can I generate?
Standard: IADC daily drilling report, bit record, connection log, trip summary, NPT analysis. Custom reports can be built using drag‑and‑drop widgets. All reports export to PDF, Excel, or can be emailed automatically.
Q8: How do predictive maintenance alerts work?
The machine learning model is trained on your rig’s historical data (or industry data, if you are a first‑time user). When sensor trends match pre‑failure patterns, the system sends an alert to the driller and remote supervisor. Typical lead time: 1‑4 weeks before failure.
Q9: What is the typical lead time for a digital drilling rig?
New build ZJ50‑ZJ70 with Level 2 digital package: 8‑10 months. Level 3‑4 adds 2‑3 months for software integration. Retrofit on existing rig: 2‑4 weeks for Level 2.
