oa Improving Gas Reservoir Management by Allocating Production with Multi Flow Rate Sampling and Geochemical Condensate Characterisation

In layered gas reservoirs, respective contribution of each produced layer is determined for efficient and reliable Reservoir Management. The Production Logging Tool (PLT) is commonly used to allocate the production to individual layers. The PLT acquisitions schedule is constrained by cost and logistics, which might prevent to get the desired frequency. Geochemical tools provide additional and reliable data on the hydrocarbon fluid provenance improving accuracy of the layer-based gas rate equations. Geochemical assessment can be done at higher frequencies and at far lower cost between each PLT
