Bill Energy Services Limited was engaged by NNPC Eighteen Operating Limited to execute an emergency intervention programme covering the repair, disconnection, and restoration of two onshore wells, AKOS016L and AKOS016S. The scope brought together wellhead engineering, integrity management, and unauthorised connection removal in a coordinated three-phase workstream, executed safely and to full regulatory compliance.
Component-level restoration of the wellhead system, from initial inspection through to pressure testing and final documentation.
We conducted a comprehensive inspection and assessment of the wellhead to identify any damage or issues that necessitated repair.
We replaced faulty or damaged wellhead components, including valves, seals, connectors, flanges, and related equipment to ensure proper functionality and safety.
We performed the necessary welding and machining activities to repair or modify wellhead components to specification.
We conducted pressure testing, flow testing, and calibration of relevant instruments and equipment to ensure optimal performance following the repair.
We provided detailed documentation of the repair work performed, including a comprehensive report highlighting the methods employed, materials used, and recommendations for further maintenance.
A coordinated wellhead recovery delivered safely, on time, and to the operational integrity standards that international operators rely on.
Identification, investigation, and safe removal of unauthorised hot tapping lines compromising the integrity of the wellhead flowline system.
We thoroughly inspected the wellhead flowline to identify any unauthorised or illegal hot tapping lines that posed a potential hazard or compromised the integrity of the system.
We determined the source, purpose, and potential risks associated with the illegal hot tapping line before initiating any disconnection activity.
We disconnected and removed the illegal hot tapping line in a safe and controlled manner, following industry best practices and HSE guidelines throughout the operation.
We implemented preventive measures to deter future unauthorised connections and ensure the long-term integrity and safety of the wellhead flowline.
We documented the disconnection and removal process with photographic evidence and provided a detailed report outlining the procedures followed and all relevant findings.
Reconnection, flushing, calibration, and verification of the wellhead flowline system, returning it to fully compliant production operation.
We reconnected all authorised and compliant lines, valves, and components to restore the wellhead flowline to its normal operational configuration.
We conducted flushing operations to remove any debris or contaminants from the flowline system, followed by rigorous testing to confirm system integrity and proper functionality.
We calibrated and adjusted relevant instruments and controls to optimise the performance of the wellhead flowline system following restoration.
We verified the proper operation of the wellhead flowline system, ensuring it met all safety, environmental, and regulatory requirements.
We provided full documentation of the restoration process, including test results, calibration certificates, and details of any adjustments made to the system.
Two Wells Restored to Full Compliance
AKOS016L and AKOS016S were returned to safe, compliant production operations. The intervention combined integrity engineering, flowline restoration, and unauthorised connection removal under a single coordinated workstream, delivered to international HSE standards and supported by complete documentation for the operator's records.
