Distributed Permanent Measurement Systems

Distributed temperature and pressure measurements

Distributed temperature sensing (DTS) fiber-optic technology for permanent monitoring can provide temperature measurements over long intervals extending up to the complete length of the wellbore. Alternatively, an array of miniaturized digital temperature sensors can be used. Multidropping several pressure gauges provides distributed pressure measurements.

Detailed well profile in real time

The highly sensitive and accurate data can identify the source of changes in well performance as they occur, enabling accurate diagnostics on gas lift systems; helping to monitor completion integrity; and quickly identifying a faulty valve, unstable flow, inflow, and outflow without interrupting production. Interpretation and real-time communication software delivers actionable information to your desk for inclusion in reservoir analysis workflows. By acquiring data from multiple wells, an overall reservoir perspective can be obtained, helping to optimize the number of wells for potentially substantial savings.
