Drilling and completion solutions

Innovative Technology & Key Features

Our drilling and completion solutions incorporate engineering features that reduce NPT, simplify logistics, and extend equipment life:

• Matched pressure ratings – The BOP stack, wellhead, and tree share the same working pressure. No adapter spools, no pressure restrictions. All hydrostatically tested to 1.5× WP.

• Common material selection – Wetted parts use identical corrosion‑resistant alloys (low‑temp carbon steel, 316L stainless, Inconel). Compatible with sweet, sour, or high‑CO₂ environments.

• Standardized connection interfaces – Flange drilling patterns, ring groove sizes, and bolt dimensions are consistent across the entire well system. Installation crews do not need different torque wrenches or gaskets for each component.

• Interchangeable valve actuators – The same hydraulic actuator fits gate valves on the BOP manifold, choke manifold, and Christmas tree. Reduced spare parts inventory.

• PR2 performance verification – Wellhead and tree components are tested to API 6A PR2 (pressure and temperature cycling) for high‑reliability wells.

• Online specification configurator – Select pressure, material, temperature, and connection type. The system generates a complete BOM, datasheets, and 3D models for the entire well package – in minutes.

• Single‑source documentation – One binder containing all API certificates, material test reports, NDE reports, hydrostatic charts, and as‑built drawings for the drilling rig, BOP, wellhead, tree, and valves.

• Lifecycle support – We do not disappear after delivery. Spare parts (seal kits, valve stems, sensors) are stocked regionally. Our field technicians can commission the entire system from mast to tree.

Why Choose SJ Petro for Drilling & Completion Solutions?

• One source, one warranty – Drilling rig, BOP, wellhead, tree, valves, and control system from a single manufacturer. No finger‑pointing between drilling and completion contractors. One warranty, one service team.

• Sinopec‑backed engineering scale – As a direct subsidiary of China’s largest oilfield equipment group, we have 314 R&D engineers, 2,100+ precision machines, and a 180,000+ m² manufacturing campus. We do not subcontract critical components – we forge, machine, heat treat, assemble, and test them in‑house.

• API 6A, 16A, 16C, 16D, 7K, 8C certified – Full compliance. Third‑party inspection (ABS, DNV, BV, SGS) is welcome. API monogram available on request.

• Field‑proven integration – Over 500 integrated drilling and completion packages delivered globally. Our systems have drilled and completed wells from 500 m to 9,000 m.

• Matched interfaces from the start – We do not design the drilling rig in isolation. The BOP stack is designed to mount directly on the wellhead, the tree uses the same flange standard, and the hydraulic control system powers both the BOP and the tree valves – no adapters.

• Simplified documentation – One binder containing all API certificates, material test reports, NDE reports, hydrostatic test charts, and as‑built drawings for the entire system. Regulatory submissions are straightforward.

• Global logistics & field service – We have shipped complete well packages to 30+ countries. Our technicians hold offshore survival certification and can commission the rig, BOP, wellhead, and tree in a single mobilization.

• Competitive package pricing – Bundling drilling and completion equipment reduces overall project cost by 10‑15% compared to separate procurement from multiple vendors. Volume discounts, shared engineering, and consolidated shipping.

• Warranty – 12‑24 months on all equipment (depending on component). Unified warranty – no exceptions for "wellhead vs. rig.”

Frequently Asked Questions (FAQ)

Q1: What is the advantage of buying drilling and completion equipment from the same manufacturer?
Matched interfaces (pressure, material, connections), single point of responsibility, simplified documentation, and 10‑15% lower total package cost compared to separate purchases. If a problem occurs at the interface between the BOP and the wellhead, you have one team to call – not two suppliers blaming each other.

Q2: Can you supply a complete package including the drilling rig, BOP, and wellhead for an offshore platform?
Yes. We offer fully integrated offshore solutions – platform drilling rig (skid‑mounted), BOP stack (compact design), wellhead, and Christmas tree. All components are marine‑coated, ATEX certified, and can be classed with ABS, DNV, or BV. We have delivered similar packages to South China Sea platforms.

Q3: How do you handle differences in pressure rating between drilling and completion equipment?
We do not – we eliminate them. The BOP, wellhead, and tree are specified with the same working pressure (5K, 10K, 15K, or 20K PSI). This is a core principle of our integrated solutions. If your well requires a higher completion pressure than drilling pressure, we design the BOP to match the higher rating – no compromises.

Q4: What documentation do you provide for a complete well package?
You receive a digital binder containing: API certificates for each component, material test reports (EN 10204 3.1) with heat numbers, dimensional inspection reports, NDE reports (MPI/UT), hydrostatic test certificates, function test certificates (for valves and BOPs), as‑built drawings, and an integrated operation & maintenance manual. All documents are indexed and searchable.

Q5: Can you customize the wellhead connection to match an existing platform or subsea template?
Absolutely. If you have an existing wellhead or a proprietary connector, we will design the BOP stack or Christmas tree to match that interface. We also manufacture custom adapter spools. Provide the connector drawing and we will engineer the solution.

Q6: What is the typical lead time for an integrated drilling and completion package?
For a standard land package (ZJ‑50 rig, 10K BOP, 10K tree): 10‑12 months from order to factory acceptance test (FAT). For offshore or HP/HT packages: 14‑16 months. We can expedite emergency projects to 8‑9 months for standard configurations.

Q7: Do you provide training for drilling and completion crews on your integrated system?
Yes. We offer a 3‑week combined training program: 2 weeks on drilling rig operation (top drive, drawworks, BOP control) and 1 week on wellhead, tree installation, and valve actuation. Training can be at our factory, your wellsite, or both. Simulator‑based training is also available.

Q8: How do you ensure spare parts availability for both drilling and completion equipment?
We stock common wear parts (seal kits, valve stems, sensors, brake pads, filter elements) for both drilling and completion components in our regional warehouses (Dubai, Singapore, Houston agent). The same part numbers are used across the system – for example, the same seal kit fits BOP rams and tree gate valves. Reduced inventory for you.
