Northside: Tracers and Production Logs: Case Studies from the Eagle Ford Shale

The evolution to horizontal wellbores requires a similar evolution in measuring and monitoring wellbore production. Tools commonly used in vertical wellbores have not been adequately indicating horizontal production characteristics, and in many cases have not been utilized due to cost.  However, an approach taken by trending the internal wellbore data during the initial phase of production, and in some cases long-term monitoring, has provided insights to wellbore operational characteristics that can be modeled in the new complex hydraulic fracture simulators being incorporated in the design and optimization of infill wellbores to better understand the rock properties, wellbore effect on nearby wells and EURs. With many operators moving to infill well development, an option to monitor the stimulation effect on the new and existing wellbores by the use of tracers is opening the evaluation of the rock properties to new understanding.  This presentation will be focused on a review of Production Log responses compared to Tracer production to highlight the difference between a discrete measurement and a production trend over time.

 

Case histories will be shown that show the productive performance as indicated by tracer production against production logging tools with commentary on the correlations and discrepancies.
