Factors That Influence Drilling and Completion Pricing
Understanding what drives cost helps you make informed procurement decisions:
Depth Capacity & Rig Size
The most significant factor. A ZJ40 rig (4,000 m depth) costs approximately 40–50% of a ZJ90 rig (9,000 m depth) due to larger drawworks, heavier mast, higher‑capacity mud pumps, and more robust substructure.
Automation Level
Semi‑automated (iron roughneck + power catwalk) adds 15–25% to base rig price. Fully automated (adds floor manipulator + monkey board robot + unified HMI) adds 30–45%. Automation reduces crew count and improves safety, with payback typically within 12–24 months.
Environmental Rating (Arctic vs. Standard)
Arctic‑rated equipment (-45°C continuous) costs 18–25% more than standard (-20°C) due to impact‑tested steel, low‑temperature seals, heated enclosures, and special hydraulic fluids. SJ Petro’s national‑level low‑temperature testing laboratory validates every component.
Material Class for Sour Service (H₂S/CO₂)
Wellhead and valve materials in class EE, FF or HH (NACE MR0175 compliant) cost 30–100% more than standard AA/BB materials due to premium alloys (13% Chrome, 17‑4PH, Inconel) and strict hardness control.
API PSL Level (Product Specification Level)
Higher PSL levels (PSL 2, 3, 4) require additional NDT, stricter material traceability, and more rigorous documentation. Price increases range from 10% (PSL 2 vs PSL 1) to 30–50% (PSL 4 vs PSL 1).
Quantity & Packaging
Fleet orders (multiple rigs or large OCTG packages) qualify for volume discounts – typically 5–15% for orders over $5 million. Export packing (sea‑worthy crating, corrosion prevention) adds 2–5% to equipment cost.

Frequently Asked Questions (FAQ)
Q1: What is the typical total cost of a complete drilling and completion package for a 4,000‑m well?
A: A complete package for a ZJ40 rig (semi‑automated) with API 6A wellhead, 5,000 m of 5‑½″ casing, Kingdream downhole motor and PDC bits, plus cementing unit would typically range from $15 – 20 million USD (FOB China). The exact cost depends on formation type, automation level, and third‑party inspection requirements.
Q2: Are SJ Petro's prices competitive with European or American manufacturers?
A: SJ Petro's factory‑direct prices are typically 30–50% lower than equivalent American or European brands for the same API specification, due to lower labour and overhead costs. Quality is maintained through API monogram certification and third‑party inspection.
Q3: Do your prices include API documentation and certification?
A: Yes. All prices include complete API documentation: material test reports (MTRs), dimensional inspection records, NDT reports, hydrostatic test certificates, and certificate of conformance. Third‑party inspection (BV, SGS, DNV, ABS) is available at additional cost.
Q4: What is the lead time for a drilling rig order?
A: Standard lead time for a ZJ series rig is 8–10 months from order confirmation to FOB port shipment. Workover rigs: 6–8 months. OCTG pipe: 4–6 weeks. Wellhead equipment: 6–8 weeks. Custom environmental ratings (Arctic, desert) add 2–3 months.
Q5: Do you offer financing or lease options for drilling and completion equipment?
A: We can refer qualified customers to financing partners who offer equipment leasing, term loans, and lease‑to‑own structures. Standard payment terms for direct purchase: 30% deposit, 40% against documentation, 30% before shipping.
Q6: What is the additional cost for Arctic‑rated equipment?
A: Arctic‑rated (-45°C) drilling rigs cost 18–25% more than standard (-20°C) rigs. This includes impact‑tested steel, cold‑hardened seals and lubricants, heated enclosures, and low‑temperature hydraulic systems. Wellhead and valve Arctic ratings add 10–20%.
Q7: How much does automation add to rig price?
A: Semi‑automated (iron roughneck + power catwalk) adds 15–25% to base rig price. Fully automated (adds floor manipulator + monkey board robot + unified HMI) adds 30–45%. Automation reduces crew count from 5‑6 to 2‑3 personnel, typically paying for itself within 12‑24 months of operation.
Q8: Can you provide a fixed‑price quotation for a complete well construction package?
A: Yes. Contact our export sales team with your well depth, formation, environmental conditions, and expected completion method. We will provide a detailed technical proposal and firm fixed price for the complete equipment package.
Q9: What is your warranty on drilling and completion equipment?
A: Standard warranty is 12 months from shipment against defects in material and workmanship. Extended warranties (up to 5 years) are available for drilling rigs and wellhead equipment. Downhole tools (bits, motors) carry shorter warranties due to consumable nature – typically 90 days to 6 months.
