Having assembled as they were in yesterday’s photo, our vibs were now facing a wall of sand.
Here’s another photo of the front crew for whom it is almost break time. The line continues over the dunes in the distance but this load of geophones runs out at the truck. They’ve two more stations to go before they get a break.
So Front Crew laid the geophones. As this photo from January 1991, shows, while the sun may be beating down, it’s not always hot in the desert.
Today’s photo, ‘Calanscio Vibroseis’ shows our seismic line stretching out from one set of dunes and across a plain towards another distant dune line.
Today’s photo is of the recording setup for an LVL shot somewhere in the jungle of Brunei inland from Seria. The crew member in the red overalls in the background is most probably checking the connection of some component of our spread – either a geophone or an explosives connection. They guy in the foreground is standing by the triggering device.
Actually, the shot below is of a pretty shoddy job. If we’d done it properly, as we did most of the time, there wouldn’t have been any blow-out. Here, a large part of the energy of the charge is moving upwards as the shot hole blows out and the noise generated when the dirt falls back to the ground also degrades the signal. But when a shot goes well, there’s nothing to photograph.
