An impulse-based single-borehole radar prototype has been developed for well logging. The borehole radar is comprised of subsurface sonde and surface equipment. An armored 7-conductor well logging cable is used to connect subsurface sonde and surface equipment which is well compatible with the other well logging instruments. The performance experiments of the prototype have been conducted in a ...

The prediction of reservoir parameters is the most important part evaluation, and porosity very among many parameters. In order to accurately measure core, it necessary take cores for indoor experiments, which tedious difficult. To solve this problem, paper introduces machine learning models estimate through logging paper, gated recurrent unit neural network based on quantile regression method ...

In the Middle East, there remain many technical challenges in water saturation evaluation of carbonate rocks and effective identification reservoir fluid properties. The traditional Archie equation is not applicable to reservoirs with complex pore structures varying space distribution, as are obvious “non-Archie” phenomena. this paper, by analyzing experimental data on rock resistivity target f...

A new type of logs, the command log, is being employed to replace the traditional data log (e.g., ARIES log) in the inmemory databases. Instead of recording how the tuples are updated, a command log only tracks the transactions being executed, thereby effectively reducing the size of the log and improving the performance. Command logging on the other hand increases the cost of recovery, because...
