Abstract

Summary

The issues of development of a method for quantitative formation evaluation in horizontal and highly deviated wells have been unaddressed for a long time due to complexities of geophysical fields distribution in such conditions and absence of proven algorithms of well logs forward solution. The latest advances in numerical modeling of nuclear and electrical well logs implemented in Techlog software made it possible to improve the quality of well log interpretation. The article presents approaches to spatial interpretation of data from horizontal and highly deviated wells using a method of forward modeling of well log response and reconstruction of “true” values of geophysical parameters of the formations intersected by a well, and compares the obtained results with actual data and conventional approaches. The first positive results were achieved, which demonstrated the prospects for further development of the research trend and the necessity of its improvement in the domain of account for the anisotropy of acoustic rock properties, reconstruction of true values of p- and s-waves, and seismic facies modeling
