Optimizing the electrologging and electro-thermal effects in cased wells via the transformations of the column's construction

(Khusid M.D. Kashik A.S. Knizhnerman L.A. )

Development and improvement of methods and tools, allowing to monitor the changes of different fluids’ (or gas) saturation in various reservoirs through the casing, is promising. The efficiency of the casing’s transformations are shown on the example of the electrical logging of cased well using probe KR-1 and the modeling of electrothermal impact on the near-wellbore area. The authors conclude that the proposed modifications of the casing’s design make measurements more accurate and reliable, allow to repress the distortion caused by the presence of noise in the output measuring transducers, and also support more rational and full use of natural resources avoiding new wells construction.......

Evaluating influence of power lead's electromagnetic induction on the measurement data with frequency dispersion method and middle gradient device

(Tkachev A.V. Khasanov I.M. )

Distorting influence on results of measuring with frequency dispersion method and device of middle gradient currency of electromagnetic induction generated by power leads is discussed. The algorithm of induction influence evaluation and it’s realization in MathCAD is described. The efficiency of its functioning is approved by applying the method on field observations results.......
