| An activation method and a mechanism in which a pressure or flow sensor senses the pressure or flow rate of the treatment fluid being pumped through the drill string. A controller powered by a power source monitors the sensed pressure or flow rate within a first time window and via a suitable activator activates a first downhole tool or operation mode thereof if the sensed pressure or flow rate is stable with that time window. The controller monitors the sensed pressure or flow rate within a second time window and activates a second downhole tool or second operation mode of the first downhole tool if the sensed pressure or flow rate is stable with that time window. In one embodiment, the sensed pressure is combined with a rotation sensor sensing the rotation of the drill string. The controller logs the starting time for the pumping and the rotation. | ||||||

| 159 | BOREHOLE WALL IMAGING TOOL HAVING A GROOVED WALL-CONTACTING FACE | EP14888718 | 2014-04-08 | EP3100075A4 | 2017-10-18 | SAN MARTIN LUIS EMILIO |
| Various disclosed borehole imaging tools and methods provide an improved high-resolution electrode configuration suitable for imaging in both water-based and oil-based muds. In at least some embodiments, the imaging tools employ a unitary conductive body to provide a wall-contacting face with grooves that define multiple sensing surfaces. Toroids may be seated in the grooves around each sensing surface for measuring the current flow through each sensing surface. Such placement enables a nearly ideal equipotential surface to be maintained and a straightforward “full coverage” electrode configuration due to a minimal electrode separation. Moreover, the disclosed configuration promises robust and reliable performance in the hostile conditions often experienced by logging while drilling (LWD) tools. This wall-contacting face can be provided on an extendable sensor pad or embedded on the outer surface of a LWD stabilizer fin. | ||||||
