Abstract The application of distributed temperature sensors DTS to monitor producing zones of horizontal well through a real-time measurement of a temperature profile is becoming increasingly popular.
Water production logging in horizontal wells – ScienceDirect
Petroleum Volume 1, Issue 4DecemberPages open access. Examples are shown illustrating the location and quantification of the flow profiles and fluid distribution in producing wells. This paper reviews new integrated production logging methods of evaluating multiphase flow in horizontal wells. Temperature response type curves show that the larger skin factor we set, the less temperature augmenter production logging theoretical and interpretive elements pdf download toe to heel could be.

In addition, larger flow rate may generate higher wellbore temperature. Under a Creative Commons license. A novel tool string combination has evolved which incorporates sensors especially targeted at the stratified flow regimes tneoretical in horizontal wells. Author links open overlay panel C.

The application of distributed temperature sensors DTS to monitor producing zones of horizontal well through a real-time measurement of a temperature profile is becoming increasingly popular.
Arriving temperature and wellbore temperature curves are plotted by computer iterative calculation. In these highly deviated or horizontal wells, conventional production logging sensors can be ambiguous in resolving multiphase flows.
Abstract New technology has enabled operators to drill an increasing number of extended reach, lateral, and horizontal wells. Production and hosting by Elsevier B. Based on mass- momentum- and energy-balance equations, this paper established a coupled model to study on temperature distribution along wellbore of fracturing horizontal wells by considering production logging theoretical and interpretive elements pdf download factor in order to predict wellbore temperature distribution and analyze the factors influencing the wellbore temperature profile.
Providing reliable production logging solutions in this difficult environment has led to the development of new sensors which can measure both the holdup and velocity of each fluid phase.
The models presented in this paper account for heat convective, fluid expansion, heat conduction, and viscous dissipative heating. The successful diagnosis and treatment of water or gas production problems requires the identification of these specific influx zones.
This information allows effective treatment of unwanted wellbore fluid entries. Independent, redundant methods are used to measure the flow parameters and enhance the accuracy of the interpreted solution. New technology has enabled operators to drill an increasing number of extended reach, lateral, and horizontal wells.

Through the study on the sensitivity analysis of skin factor and flow rate, we come to the conclusion that the higher skin factor generates larger temperature increase near the wellbore, besides, temperature along wellbore is related to both skin factors and flow rate.
