After paying $500 bail they let me out again. Next Monday I went to court, where the District Attorney appeared a good sport and let the charges down from 30mph (50km/h) over to 15-20mph. Mrs. Judge then centenced me to a $50 fine + $40 costs and I received the rest of my $500 back.... so I got my mugshot for only 90 bucks and 7 hours time, bargain! (try that in Holland). All in all a nice experience....

Somewhere this week, at 5.45 in the morning I met Anthony the Deputy Sheriff as he drove in the opposite direction as I was through the little valley where I worked. Unluckily for me he switched on his radar device to discover that I was having fun on the winding mounain road.... at 80 mph (honestly, who really drives 50 at that time of the day). Outrunning was not an option as the valley does not have any hiding or turnoff opportunities (I did try it for a couple of minutes anyway, as he was about 1 km behind me and did not gain....). In the end I decided it might be cheaper to stop and wait for him. After taking a look at my beautiful Dutch drivers' licence he decided he had to arrest (!) me and let me pay a bail bond in order for me to show up in court.... So I followed him to his office (50 km in the opposite direction) where he booked me in... He was a good sport though and let me take his picture.

The principle behind flooded reverse drilling: The rods are actually double walled, made up of an inner and outer rod. Around the outer rod there is drilling mud that fills the hole. In the annulus between the two rods air is pumped down, which enters the inner rod near the bit. The mud in the inner rod becomes less dense than the outside mud due to the air bubbles in it and flows up.
This is the site where I will be working with this week, with a Lang LM200 rig in the center. Method of drilling is 'flooded reverse rotary' with which you can drill in very difficult ground conditions. In fact Lang is hired in this case to drill the first 800m for Exxon, as they are having severe trouble... After the 800 m Exxon comes in with a large oilfield rig to drill down to a gas reserve at 1500m.
The coming weeks I'll be working for Lang Exploratory Drilling. This company was aquired in the early '80s by Boart Longyear and now makes and uses the big stuff: rigs for rotary drilling. In the picture their latest creation: the LM700, about twice as big than the next largest rig they have ever made. It will be used to drill through the overburden (first couple of hundred meters), after this it will make way for an oilfield rig that will drill the rest down to a gas reserve.
