Application Fields
1. Onshore Multi‑Well Pad Drilling (Shale Gas, Tight Gas, CBM)
The classic deployment for digital rigs. Hundreds of connections per well, dozens of wells per pad – automation pays back quickly. Idrilling has demonstrated an average 19.34% ROP increase across nearly 400 wells in deep formations, shale gas, and tight gas reservoirs. [15†L9-L13] IoT sensing and real‑time optimization reduce connection time and eliminate manual errors.
2. Deep & Ultra‑Deep Well Drilling (5,000m – 9,000m+)
Deep wells demand precision and efficiency. SJ's ZJ90DB digital rigs have been deployed in Kuwait's northern oilfields to 9,000 meters – and in field service in China's northwest region, reaching a maximum depth of 9,270 meters. Advanced automation controls, VFD power, and integrated towing capability enable efficient operation in deep wells.
3. Offshore Platform Drilling
Space is tight, HSE requirements are stringent, and remote support is essential. Our digital rigs are equipped with dual driller ring network integrated control systems and automated catwalks – unified centralized management of rig parameters and controls with minimal personnel on board.RTOC remote support enables shore‑based experts to monitor and assist multiple platforms simultaneously.
4. Desert & Harsh Environment Drilling (Middle East, North Africa)
The ZJ90DB rigs deployed in Kuwait feature integrated automation controls, positive pressure explosion‑proof driller's cabin, VFD power, and modular design with integrated towing – specifically tailored for high‑temperature, sandy environments.The first rig achieved first spud 73 days ahead of contract schedule, demonstrating the efficiency of digital rig deployment in extreme conditions.
5. Workover & Well Intervention
Our XJ series self‑propelled workover rigs (XJ150 through XJ1200, 300‑2,250 kN static load, 235‑1,300 HP) incorporate the same AC VFD technology and automation features – automated catwalks, automated pipe handling, and one‑click activation of automated drill feeding.
6. Fleet‑Wide Digital Management via RTOC
For operators with multiple rigs, Sinopec's RTOC technology – the abbreviation for Remote Technical Operations Center – is a core drilling optimization and decision‑making technology with 100% proprietary intellectual property rights, capable of simultaneously managing hundreds of wells online. [17†L26-L29][17†L18-L20] The system integrates wellbore risk warning, drilling parameter optimization, 3D geosteering, automated cementing, fracturing remote monitoring, and construction KPI analysis. One experienced drilling supervisor can support 3 rigs simultaneously, with AI‑powered early warning for lost circulation, stuck pipe, and other events enabling proactive intervention before problems escalate.The RTOC platform transitions drilling from "experience‑driven" to "science‑driven" operations.

FAQ – Digital Rigs
Q1: What makes a drilling rig "digital" rather than just "automated"?
A digital rig is built on three core capabilities: (1) AC VFD digital drive architecture as the electrical backbone; (2) integrated automation across catwalk, manipulator, iron roughneck, and monkey board; and (3) connected intelligence – real‑time data transmission, remote monitoring, AI‑driven optimization, and predictive analytics. A rig can have automation without being fully "digital" – but a digital rig combines automation with data connectivity and intelligent decision‑making. [0†L7-L9]
Q2: What is Sinopec's Idrilling (Yinglong) scientific drilling system?
Idrilling is Sinopec's first self‑developed scientific drilling system – integrating IoT sensing, scientific decision‑making, and closed‑loop control into a unified digital drilling platform. Using the "Great Wall Large Model" AI, the system automatically generates drilling plans, optimizes parameters in real time, and ensures precise control from the drill bit to surface equipment. [15†L20-L22] The system has been deployed in nearly 400 wells, achieving an average 19.34% ROP increase and a 12.93% drilling cycle reduction. [15†L9-L13]
Q3: How does AC VFD drive technology benefit digital rig operations?
AC VFD systems have fewer electrical connections, better motor efficiency, less waste heat, and better power distribution than conventional DC systems. [16†L5-L9] For digital operations, the key advantages are precise speed and torque control (enabling automated sequences), predictive diagnostics (identifying potential failures before they cause downtime), and seamless integration with automation platforms like SmartROS or Idrilling.
Q4: What is RTOC and how does it work with digital rigs?
RTOC (Remote Technical Operations Center) is Sinopec's core drilling optimization and decision‑making technology with 100% proprietary intellectual property rights. [17†L26-L29] The system integrates wellbore risk warning, drilling parameter optimization, 3D geosteering, automated cementing, fracturing remote monitoring, and construction KPI analysis – capable of simultaneously managing hundreds of wells online. [17†L18-L20] Digital rigs transmit real‑time data to the RTOC, enabling remote experts to support multiple rigs simultaneously – one experienced drilling supervisor can support 3 rigs, with AI‑powered early warning for lost circulation, stuck pipe, and other events.
Q5: Can an existing conventional rig be converted to a digital rig?
Yes – absolutely. Our retro kit adds AC VFD controls, automation components, and RTOC connectivity to existing rigs. Start with basic data acquisition, add the automated catwalk, then the manipulator, then the iron roughneck, and build toward full digital operation over time. This incremental approach protects your existing capital investment while delivering immediate benefits from each added component.
Q6: What is the typical lead time for a digital rig?
-
Standard AC VFD digital rig (4,000‑7,000m): 9‑12 months from order confirmation
-
Fully automated digital rig with full automation suite: 12‑18 months
-
Idrilling‑integrated digital rig: 12‑15 months
The 9,000‑meter ZJ90DB digital rigs for Kuwait were delivered within approximately 9 months from order to first shipment. [14†L4-L7]
Q7: What certifications do SJ digital rigs carry?
SJ facilities maintain API Q1, API 4F, API 7K, API 8C, ISO 9001, ISO 14001, and OHSAS 18001 certifications. [3†L35-L37] Complete documentation packages are available for international tenders and client audits. Our AC VFD drilling rigs are designed and manufactured in accordance with API Spec Q1, 4F, 7K, 8C, and 9A standards.
Q8: Can SJ digital rigs be operated remotely?
Yes – depending on local regulations and operator requirements. Our RTOC‑compatible architecture enables real‑time data transmission, remote monitoring, and remote expert support. For fully remote operation, additional cybersecurity and control infrastructure is required – contact our engineering team for custom remote operation solutions.
Q9: What are the biggest ROI drivers for digital rigs?
Based on industry data, the key ROI drivers are: (1) personnel reduction – ranging from 22‑77% depending on automation level; (2) NPT reduction – up to 79% for operational NPT; (3) rig time savings – 16‑33% efficiency improvement; (4) fuel savings – 5‑8 gallons per hour per rig; (5) maintenance cost reduction – up to 20% in repair and maintenance expenditures.
