Abstract:
1. A method of securing or coupling at least one geophysical sensor in a string of geophysical sensors to a borehole, the at least one geophysical sensor comprising at least one geophysical transducer and an expandable member configured to be deployed into an open or expanded position when the at least one geophysical sensor is located at a desired depth in the borehole, the borehole having sidewalls, at least portions of the expandable member being configured to engage at least portions of the sidewalls to prevent the passage of a securing or coupling material therearound or therethrough when the securing or coupling material is poured around or atop at least portions of the at least one geophysical sensor when the expandable member is in the open or expanded position, comprising: lowering the string into the borehole to a desired depth; expanding the expandable member into the open position such that the expandable member engages the at least portions of the sidewall; pouring the securing or coupling material into the borehole around or atop at the at least portions of the at least one geophysical sensor, and permitting the securing or coupling material to substantially to cure or solidify in place around the at least one sensor.
