Frequently Asked Questions (FAQ) – For Procurement & Engineering
Q1: What makes SJ Petro different from other Chinese drilling equipment manufacturers?
We are a Sinopec subsidiary – not a private trading company. We manufacture our own masts, drawworks, top drives, and BOPs. We hold API monograms. And we have delivered over 500 rigs globally – many to national oil companies and major contractors.
Q2: Are your rigs API certified?
Yes. Our rigs are designed and built to API 4F (structures), 7K (hoisting and pumping), 8C (wireline), and 16A (BOPs). We can provide API monogramming upon request (additional fees apply).
Q3: Do you offer rigs for desert or arctic conditions?
Absolutely. We have desert packages (55°C ambient, sand filtration, oversized coolers) and arctic packages (-40°C, heated cabins, low‑temp hydraulics). Over 150 desert rigs delivered to Middle East and Africa.
Q4: Can you retrofit a skidding/walking system to our existing rig?
Yes – we have retrofit over 30 rigs with hydraulic skidding or walking systems. A site survey is required to design the bolt‑on substructure extensions.
Q5: What is the typical lead time for a 5,000m land drilling rig?
10‑12 months from contract to FOB China port for a standard configuration. Custom or deep‑rated rigs (7,000‑9,000m) require 12‑16 months.
Q6: Do you provide financing or leasing?
Yes – through our leasing partners. Operating leases (off‑balance‑sheet) and finance leases are available for qualified clients. Minimum contract value $5M USD.
Q7: Do you supply spare parts for older SJ Petro rigs (10+ years)?
Yes – we guarantee spares availability for 15 years after last production date. For rigs older than that, we can often custom‑machine parts from original drawings.
Q8: What documentation comes with a rig?
Full package: dimensional drawings, hydraulic/electrical schematics, bill of materials, API certificates, material test reports (MTRs), operating and maintenance manuals, and factory test records.
Q9: Do you provide installation and commissioning?
Yes – our field service team supervises rig‑up, conducts load tests, trains your crew, and stays until first well spuds. Typical on‑site time: 4‑8 weeks depending on rig size.
Q10: Can you customize a rig for a specific pad layout (e.g., dual‑well, offset)?
Yes – we design custom substructures with well center spacing as tight as 3 meters. We also supply integrated skidding/walking systems for multi‑well pads.
Q11: What is your warranty?
18 months from shipment or 12 months from commissioning (whichever first). Extended warranties available for fleet operators.
Q12: How do I get a quote for a drilling rig?
Provide: desired depth, casing program, hook load, drive preference (AC/DC/mechanical), environment (land/offshore/desert/arctic), and any special requirements. We will respond with a technical proposal and fixed price within 10 business days.
