Applications – Where Our Wellhead Automation Solutions Deliver

• Onshore conventional oil & gas fields – replace manual wellhead checks with remote monitoring; reduce truck rolls; capture production data automatically.

• Offshore platforms – integrate WHCPs with platform DCS; reduce personnel exposure in hazardous areas; meet API 14C safety requirements.

• Unconventional (shale / tight) fields – control dozens of wells from a central pad equipment building; optimise plunger‑lift and intermittent wells automatically.

• High‑pressure, high‑temperature (HPHT) wells – SIL‑rated ESD, API 6A components rated to 20,000 PSI, sensors up to 250°F.

• Remote & unmanned well sites – solar‑powered WHCP with cellular/satellite communication; autonomous ESD; low maintenance.

• Enhanced oil recovery (EOR) / injection wells – remote adjustment of injection rates; real‑time pressure monitoring to avoid formation damage.

• Abandoned well monitoring – low‑cost solar WHCP with pressure and gas detection; regulatory compliance without site visits.

• Cluster well pads – master‑local system reduces panel count; each well operates independently; fast expansion.

Product Types – Wellhead Automation Solutions We Offer

Frequently Asked Questions (FAQ) – Wellhead Automation Solutions

Q1: What is included in a "complete wellhead automation solution” from SJ Petro?

A: Our complete solution typically includes: API 6A wellhead valves and Christmas tree (if required), WHCP with RTU/PLC and local HMI, pressure/temperature sensors, actuators (hydraulic/pneumatic/electric/solar), fusible plug fire protection, ESD logic (SIL‑2/3), SCADA software (local or cloud), communication equipment (cellular/satellite/radio), on‑site commissioning, and operator training. We can also provide solar panels, battery banks, and installation materials. Everything is designed to work together.

Q2: Can you retrofit automation to my existing wellhead valves?

A: Yes. If you already have API 6A gate valves and Christmas trees, we can add actuator kits (hydraulic/pneumatic/electric) and connect them to a new WHCP. We will also install the necessary sensors (pressure, temperature, position). The existing wellhead does not need to be replaced.

Q3: What is the lead time for a wellhead automation solution?

A: Standard lead times:

• Single‑well WHCP: 6–8 weeks

• Multi‑well master‑local system (up to 6 wells): 10–12 weeks

• Full‑field SCADA (20+ wells): 14–20 weeks (depends on well count)

• Solar or arctic packages: add 4–6 weeks

Expedited options may be available – contact our sales team.

Q4: Do you offer leasing or financing for wellhead automation solutions?

A: Yes. For qualified buyers, we offer direct financing (partner banks, up to 5 years), operating leases (low monthly payments, return at end), and milestone payment plans (30/40/30). Contact our solutions team for a lease proposal.

Q5: What training do you provide for our operators and maintenance staff?

A: For every solution, we include 2–5 days of on‑site training during commissioning. Topics covered: WHCP local operation, SCADA dashboard navigation, alarm handling, ESD testing, basic troubleshooting, and preventive maintenance. We also provide digital manuals, video tutorials, and 6 months of remote support.

Q6: How does your SCADA handle loss of communication?

A: Each WHCP has an embedded data historian. When communication is lost, the WHCP continues to log data locally and executes all ESD and control logic autonomously. When communication is restored, the SCADA server automatically retrieves the backlogged data. No data is lost.

Q7: Can your solution work with my existing wellhead safety system (HIPPS, separate ESD)?

A: Yes. Our WHCP can be integrated with existing high‑integrity pressure protection systems (HIPPS) and facility ESD networks. We support hardwired shutdown signals (dry contacts) and communication‑based commands via Modbus or DNP3.

Q8: What is the warranty on a wellhead automation solution?

A: 12 months after commissioning or 18 months after shipment – whichever occurs first. Coverage includes all components (WHCP, sensors, actuators, SCADA software). Wear parts (filters, batteries) are not covered but are available as spares. Extended warranty (up to 5 years) is available.

Q9: Do you provide spare parts and emergency support internationally?

A: Yes. We maintain a global inventory of WHCP components, sensors, actuators, and API 6A valve parts. Emergency spares ship via DHL/FedEx within 24 hours. For large fleets, we can establish a local consignment stock. Remote diagnostic support is available 24/7 via video call.
