In 2016, we worked together with our Industrial Gases client to develop a solution that would allow them to generate on-site reports for the stimulation of oil wells through nitrogen injection. That year, we developed and manufactured 36 systems tailored to the needs of the application, and since then, we have continued to manufacture more units according to our client’s requirements.

Background

  • The client attends to services requested by Pemex personnel for nitrogen injection in the wells.
  • Once the service is considered completed by a Pemex supervisor, official reports need to be generated for the service to be accepted and for the invoice to be processed.
  • The injection sites were distributed in the jungle areas of Tabasco and Campeche, and also in Altamira, Tamaulipas.
  • As there was no system in place for generating reports on site, a client supervisor had to collect the data stored on a memory device in the injection unit, transport it to the office in Villahermosa, Tabasco, and there manually download the records, create the reports in Excel, and then return to the well area to find the Pemex supervisor. This process could take more than 60 calendar days due to the difficulty of locating the supervisor for each service in the well area.

The Solution

A customized solution was developed based on software installed on an industrial computer that would accumulate the process variables and, upon completion of the service, could immediately generate the necessary reports to be signed by the Pemex supervisor while he was still on-site. This system dramatically reduced the delay time for submitting the service invoice to Pemex.

The SGR System is a specialized solution developed for Nitrogen Stimulation of Oil Wells, designed to provide real-time monitoring and automated generation of field service reports. It is based on custom-built software running on an industrial-grade PC, installed inside mobile nitrogen injection units.

Key Functions and Capabilities:

  • Real-time monitoring of critical injection parameters: flow, pressure, and injected volume totalizer
  • Logging of work orders, operator details, and specific service configurations
  • Graphical display of parameter trends throughout the injection operation
  • Export and import of service segments between different units for traceability
  • On-site generation and printing of PEMEX-compliant service reports
  • Historical database of all operations performed by each unit
  • IP65-rated hardware, built to resist the demanding conditions of oilfield environments

The system collects process variables—such as pressure, flow, and accumulated nitrogen consumption—via Modbus RTU communication with measurement instruments, primarily Emerson FloBoss devices.

Additionally, the system can be optionally equipped with a cellular modem, enabling automatic transmission of reports and operational data via email to central distribution offices.
