Why Choose SJ Petro for Drilling & Completion Specifications?
-
Complete, standardized format – Every spec sheet follows the same structure: general data, dimensional drawing, material list, test requirements, and recommended spares. No surprises.
-
API 6A, 16A, 16D, 7K, 8C compliant – All published specifications are within API tolerances. We do not invent "special” dimensions that force you to buy proprietary spares.
-
Third‑party cross‑checked – ABS, DNV, and BV have reviewed our specification templates. Many are pre‑approved for class notation.
-
Digital tools for engineers – Online configurator, CAD models (STEP/IGES), and spec change alerts save hundreds of hours of research.
-
Custom specification development – If your project requires non‑standard pressures, materials, or dimensions, we write a custom spec sheet for you, including drawings and test plan.
-
No charge for specification sheets – Full datasheets are free to download (registration required for high‑res drawings). We do not hide basic specs behind salespeople.
-
Global compatibility – We specify flange drilling to ISO, ASME, and GOST standards. Connection threads to API, also to DIN or BS if requested.
-
Long‑term support – Spec sheets are version‑controlled. We keep superseded specs available for 20 years to support legacy equipment.
-
Training & onboarding – We provide a one‑day workshop for your engineering team on how to read and apply our specifications effectively.
Frequently Asked Questions (FAQ)
Q1: Are your drilling and completion specifications available for free?
Yes. Basic 1‑page datasheets (pressure, weight, dimensions) are free. Full specification packages (20‑30 pages including test reports, material certs, and 3D models) require a free registration or a non‑disclosure agreement. No payment is ever required for spec sheets.
Q2: How do I know which material class (DD, EE, FF, HH) to choose?
DD – sweet service (no H₂S), moderate temperature. EE – low H₂S (up to 100 ppm), standard offshore. FF – high H₂S (up to 10,000 ppm). HH – high H₂S + high pressure. Our spec sheets include a selector chart. If unsure, we provide a free consultancy call.
Q3: Can you provide specifications for equipment you do not manufacture?
We publish specifications only for products we manufacture. For third‑party equipment, we can provide a cross‑reference guide showing which of our products match or exceed the other brand’s specs – useful for fleet standardization.
Q4: Do your specifications include API monogram and PR2 test levels?
Yes. For any product specified as API 6A PR2, the spec sheet includes the pressure and temperature cycling requirements and acceptance criteria. We also provide sample test reports showing actual compliance.
Q5: How often are your specifications updated?
We review every specification annually or when API standards change. Major updates (new material classes, new pressure ratings) happen when we introduce a new product line. Minor updates (typos, reference standards) are published immediately. You can subscribe to change alerts.
Q6: Can I get a custom specification for a non‑standard flange or connection?
Absolutely. Many projects require special flange drilling (e.g., metric bolt patterns) or proprietary connections. We will write a custom specification sheet and maintain it for your project only. Additional engineering fee applies.
Q7: Do you provide 3D CAD models in native formats (SolidWorks, Inventor)?
We provide STEP, IGES, and SAT files. For an additional fee, we can export to SolidWorks, Inventor, or CATIA native format. For large assemblies (complete wellhead stack or rig package), we can supply the assembly model.
Q8: What is the typical accuracy of dimensional drawings in your spec sheets?
All dimensions are toleranced per API standards (±0.5 mm for small features, ±3 mm for large). We have had third‑party verification that our as‑built dimensions stay within 0.1 mm of drawing. First‑article inspection reports available.
Q9: Can I use your specifications to directly issue a purchase order without further engineering?
Yes – many clients do. Our specification sheets include all data needed for procurement: material grade, heat treatment, surface finish, testing, marking, and certification. We accept POs referencing our spec sheet and revision number.
