GAS DRILLING SOIL SAMPLING |
摘要 |
The concentration with location at which a mobile reservoir fluid is contained within subsurface earth formations is measured by gas drilling a borehole into the earth formations while circulating a gaseous drilling fluid that is initially substantially free of the mobile reservoir fluid and measuring the concentration of the reservoir fluid in the earth formations by measuring the difference in its concentration in equivalent portions of the drilling fluid that enters and leaves the borehole.
