Since effective well management requires knowledge of downhole conditions and changes that may be occurring there, information about downhole pressure and temperature in offshore wells is essential. These measurements become even more crucial as wells go deeper, where pressures and temperatures get progressively higher. Monitoring instruments installed in deep wells must be durable enough to withstand the harsh environment and still deliver reliable measurements. In addition, downhole flow-rate, density, and watercut monitoring is needed in multi-zone wells to provide valuable information, which reservoir engineers can use to determine steps to take to improve well performance.
Global Exergy is the leader in instrumentation for downhole monitoring in deep, high temperature and high pressure wells. Durable, highly accurate instruments are available to measure the pressures and temperatures, while downhole flow rate, density, and watercut sensors effectively deliver real-time data on conditions in the various zones. This additional information is helpful in identifying such issues as formation water breakthrough and declining production, as well as the presence of gas. Reservoir managers can use this information to better control flows from different zones.
