| Summary: | The present invention relates to a remote-controlled method of drilling, analyzing, and stabilizing a subsurface formation. More particularly, the present invention relates to drilling, analyzing, and stabilizing a remotely located subsurface formation.
The present invention provides a method for drilling, analyzing, and stabilizing subsurface formations. The system is generally formed around a reusable bottomhole assembly (BHA) that provides an anchoring and thrust mechanism, furnishing the necessary downward force needed to provide comminution of geological material in a borehole. The BHA is conveyed into the borehole via a communications link wireline equiped with internal power and data telemetry lines. The BHA permits the use of multiple comminution sampling and analysis tools via a coupling device. The BHA and communications link wireline are mounted so as to couple with different tools. The main drilling mechanism is a torque drive assembly powered coring tool. A borehole televiewer and/or logging analysis tool may follow each coring period. The final step in each coring period is a wellbore consolidation technique. This series of steps is then repeated, each time coring the wellbore to a deeper depth. |
