The Essential Of Basic Russian Well Logs And Analysis Techniques

This article covers the essentials of the tools and practice of basic Russian well logs and Russian log analysis techniques used by the geophysical analyst. Emphasis is placed on those tools used in Russia which are significantly different than their counterparts in the western oil fields. This is surely a rapidly changing world. Many companies are on their way to Russia or one of its former republics, or is contemplating such a move. In truth, it might be simpler if you were going to Antarctica. The learning curve of many disciplines will be an important early part of your venture. There is a multitude of significantly different technologies to understand. Those professionals dealing with wireline logs probably will have a tougher time than most. Not only will they be evaluating logs with very unfamiliar curves and analytical techniques, but they will also have a log heading with some important information written in Russian, and no idea where to get the other equally important information. The penalty for not learning this new technology is the loss of a mountain of valuable information. The well log analyst or in Russian terminology the geophysical analyst needs to understand scaling and calibration, curve responses and many other facets of the logs to be able to obtain values from curves and correct them if necessary, for use as input into the various equations, etc. The geologist must know curve responses to know how to correlate, for example, an existing Russian log and a newly run western style log. Engineers doing recompletions will need to understand the well in which he is working. The geotechnician, digitizing a Russian log must be able to follow one curve all the way, which is no mean feat when there is no line style and the curves with which he is working are copies in black and white.
