Abstract
A mud sensing hole finder comprising: a front steering wheel assembly, a rear wheel assembly, a sensor package, a corrosion package, a ported housing, and a tapered spring joint; wherein the mud sensing hole finder is capable of attachment to a wireline logging tool-string.
Claims20
A method comprising:
- running a mud sensing hole finder into a borehole, wherein the mud sensing hole finder comprises:
- a front steering wheel assembly,
- a rear wheel assembly,
- a sensor package,
- a corrosion package,
- a ported housing,
- a tapered spring joint;
- and
- grease ports for wheel lubrication and end slots for location of anti-rotation washers with axle end bolts;
- rolling the front steering wheel assembly left or right according to a borehole geometry and rugosity;
- and
- activating the tapered spring joint to allow lateral movement of the front steering wheel assembly up over an obstruction.
