Modern Production Logging

Water identification and fluid movement in both injection and producing wells are evaluated using spinners, tracers, pulsed neutron oxygen activation, temperature and noise surveys. A variety of fluid identification devices are used to evaluate multiphase flow. These tools together are used to quantify the sources of water, oil, and gas production, and are critical to the control of excessive water or other phases. Inflow Performance Relationships (IPR) are determined for individual downhole zones. Special considerations are given for deviated and horizontal wells. The newest tools designed for horizontal applications, such as the Flagship/PS Platform or Polaris are reviewed. Numerous videos of and in vertical, deviated, and horizontal flows are used to aid in visualization of the logging environment. Distributed Temperature Sensing, DTS, a new non-intrusive temperature logging technique based on fiber optic technology is also introduced.
