Abstract
In this talk, results will be presented from recent laboratory work conducted at QuantumPro and field tests on using nanoparticle tracer embedded in perforation charges for cluster-level flow monitoring and diagnostics. Laboratory tests were performed according to API RP 19B standards to confirm that the tracers withstand charge detonation and to evaluate how much tracers can be embedded in charges without affecting charge performance. Two field tests on three wells were performed over a number of stages and many clusters to test longevity, consistency and repeatability of tracer detection. The first field test was performed to validate tracer detectability at field conditions after large hydraulic fracturing treatments, considering only a gram or less to a few grams of tracers per cluster. The second field test was to assess how long the tracers remain detectable or how long the cluster-level production monitoring will last. The field test results confirmed that nanoparticle tracers embedded in perforation charges can provide cluster-level production mapping for weeks and months.
