The Key Role of 4D SeismicProduction Data Monitoring in Heterogeneous Carbonate Reservoir Management to Unwind Master Development Plan Scenarios

摘要

One of the main challenges in developing new fields is lack of enough data for reservoir description which in turns add the ambiguity to description of reservoir model and production forecast.Managing PMS (Production Monitoring Subcommittee)as a guideline for Preservation of Hydrocarbon Committee(PHC) uses surveillance and monitoring techniques for controlling the validity of MDP. The studied reservoir is located in new explorated field with heterogeneous carbonate reservoir in southwest of Iran with unique reservoir properties.Include low permeability,high H2S content;high initial reservoir pressure with high quality oil with API gravity of 44,the miscible gas injection project was launched in early production period. The main purpose of the Reservoir management and surveillance is integrating the well flow parameters and further technical data from various sources in order to apply the technical experience and software skills to enhance the production performance.The reservoir management and surveillance procedures are approaches for data acquisition for creative analysis and interpretation of data to exploit the utmost value from each well,level and the whole field. The main tools to monitor the field as three categories, i.the different types of well testing,data acquisition and crude sampling, ii.The methodology and softwares that will be utilized to analysis the data and perform the relevant studies to evaluate and optimize the wells and field performance. iii.The gas injection monitoring procedures. All the foreseen activities for Reservoir surveillance will be presented and discussed quarterly within the Production Monitoring Subcommittee or PMS.The main objective of this study is to provide the approaches,procedures and sequence of activities to be carried out in field in order to effectively monitor and optimize the field performance.
