| Scope |
The company invites all prospective suppliers and contractors for provision of co2 welltracer non-intrusive surveillance services for offshore and onshore wells.
WellTracer or equivalent survey is based on the use of carbon dioxide (CO2) as a tracer medium, which is injected into the well along with the lift gas. The tracer’s return in the production tubing is monitored and measured at the surface. A software tool, WinGLUE or equivalent , is used to analyze the results from the WellTracer survey to determine the depth(s) of passage of the tracer from the annulus into the production tubing. The method is non-intrusive and neither well entry nor well shutdown is required to produce the desired results. The Services will be on a Call off basis. Contract Duration shall be 61.5 Months, including 1.5 Months for initial Mobilization
