Product description

Determination of the radius of penetration of drilling mud filtrate
The task
1. Determine the radius of penetration of the drilling mud filtrate into the productive formation according to your version (select the version number by the ordinal number in the credit list):
a) changing the borehole diameter - 151 mm; 165.1 mm; 190.5 mm; 215.9 mm;
b) changing the coefficient of open porosity - 5%; ten %; 15 %; 20 %;
c) changing the drilling time of the productive formation - 5 hours; 10 hours; 15 hours; 20 hours
2. Based on the data obtained, build graphs of the dependence of the radius of penetration of the drilling mud filtrate on: the diameter of the well; open porosity coefficient; time of impact on the reservoir and draw appropriate conclusions.
