Today we installed and cemented the 7 inch casing
Haliburton trucks in front of the SAFOD drill rig as the 7 inch casing was cemented in place.

Today we installed and cemented the 7-inch casing. Although we had hoped to install casing to the maximum depth reached during yesterday's hole conditioning operations (10,960 ft), borehole stability problems prevented this and, after pushing and circulating the casing through some tight spots, it encountered an obstruction at a depth of 10,546 ft MD and had to be cemented at that depth. Fortunately, the casing is set through the actively deforming fault at 10,485 ft MD. Thus, we are in an excellent position to perforate the casing directly within this fault and install monitoring instrumentation (seismometers, accelerometers, tiltmeters and a fluid pressure transducer) in the immediate vicinity of the the M2 ""Hawaii"" target earthquakes over the coming year.
