The approach for fluid inflow optimization, based on the results of the distributed temperature survey (DTS) and the simulation of supposed inflow under different conditions of the extended horizontal wells in oil rim, is described in the article.
Materials and methods
The project, based on the field experience, includes the description of problems while developing contact reservoirs; realization of technological and process solutions when tooling up the productivity sector of well bore. Well inflow temperature models for differentproduction well zones are also described in the article.
DTS was applied in a horizontal producing well of the Yu. Korchagin oil field by means of installation of a fiber optic cable as an element of the equipment complex of well completion into the effective pay. The thermal analysis over the observation period was made and temperature models of multiphase fluid inflow were constructed.
The fiber optic cable, run through the pay zone in the oil rim, allows to get theinformation about the fluid distribution along the well depth and gives understanding of well dynamics. The analysis and modeling of fluid flow, based on DTS data, gives the opportunity to make a forecast and to identify intervals of the free gas and the bottom water. Theforecast is considered to be the essential tool for engineering and management solutions for the purpose of optimizing the performance of the well and the hydrocarbon production management.
