Slickline With Fiber-Optic Distributed Temperature Monitoring for Water-Injection and Gas Lift Systems Optimization in Mexico

Abstract

Data acquisition using a portable fiber-optic Sensa tube unit has provided important information in a cost effective way. The DTS measurement provides a realtime and continuous temperature profile of the entire well, enabling the operator to monitor simultaneously all the gas lift valves, which is not possible to achieve with the usual time-consuming PLT surveys. Ultimately, the DTS monitoring has proven to be an efficient and reliable tool, saving the operator well intervention time and allowing immediate rectification of the issues observed.

Research Progress of Applying Distributed Fiber Optic Measurement Technology in Hydraulic Fracturing and Production Monitoring

“…Figure 5 shows the cooling effect of gas passing through gas-lift valve 1, corresponding to the depth information, to get the location of the gas-lift valve. Using a DTS for gas-lift monitoring not only reduces the intervention time of the well but also can quickly identify the problem and take corresponding measures in time [11,[21][22][23][24][25].…”

Gas injection for enhanced oil recovery in two-dimensional geology-based physical model of Tahe fractured-vuggy carbonate reservoirs: karst fault system

“…Besides, gas-assisted gravity flooding could make full use of gas-oil gravity difference to achieve stable gas-displacing-oil and thus a better sweep efficiency. This EOR method was successfully applied in Cantarell, a complex offshore fractured carbonate field in Mexico, and yielded an optimized oil recovery via reservoir simulation runs (Sanchez et al 2005). In the Tahe Ordovician reservoir with a thickness of almost 300 m, the oil at the lower part is mainly recovered by water flooding and the oil at the upper part is mostly produced by primary gas flooding.…”
