Diary of an oil field worker
Comments and personal experiences of my job and life, working in the oil field on oil rigs around the world. Drilling for oil and gas in Canada, Alberta, Newfoundland, Nova Scotia, Colombia, North Sea, Gulf of Mexixo, Alaska, Libya, Gabon, Brazil and Norway. Rigzone

Safe and Cold Water
It's not bad working in Colombia. There are safe areas and there are not so safe areas. I just happen to working right now in an area that is fairly safe. However a few days ago the rebels FARC blew up a pipeline near the border of Colombia and Venezuela. The rig here where I am is not where near there and hopefully that will not happen here. It is about a 4 hour drive from the rig site here to Villvavicencio the nearest good sized town. From Villavicencio it is another 3 hours drive (to 5 hours depending on truck traffic) to Bogota. As I am a foreigner, my company does not allow me to travel on that road, even if I would be with my Colombian workmates. I have to go on the 40 minute flight to Bogota. This is sometimes, not good as on one trip I could not get a flight and has to wait an extra day in Villavicencio. The only complaint that I had with the hotel is that sometimes the water is not hot. I think they turn off the hot water in the afternoon and only turn it back on for the morning showers. The rig is a bit unusual also as there is no hot water. Most rig sites do have hot water. It takes a bit to get used to and is definitely not an enjoyable experience.

Easy Money
Today was an easy day for me. I am working right now in Colombia, South America. Today the rig had problems with their equipment and so we did not drill anything. They "tripped out to the shoe" meaning they pulled all the pipe out of the hole until they were at a safe place and repaired the "top-drive" The top-drive is the drive motor that turns the drill string and the bit. So today was spent on the internet and watching TV. Easy money
Overview of my job
The division that I work for provides directional services and formation
evaluation services. Directional services means that as the well is
drilled we measure the azimuth of the hole, which is like the compass
bearing and measure the inclination, which is the angle from vertical to
horizontal. The measurement are taken every 90 feet or 30 meters and
from these measurements, the path of the hole can be determined and
plotted. In addition we have tools, behind the bit that we can
communicate with and can steer the hole in any direction or inclination
we want. Before the hole is drilled the oil company provides us with a
plan for the hole path, based on where the oil or gas is located, and we
then steer the well on this path, something like steering a car down a
road. Formation evaluation means that we measure properties of the rock
we are drilling to determine the type of rock and whether it has oil or
gas. To accomplish this we have sensors in the pipe behind the bit that
measures the rock properties and sent that information to our computer
systems on the surface. Presently there are many different types of
drill pipe tools containing many different sensors and more being
developed all the time. The most common ones are as follows. A gamma
tool measures the natural gamma radiation in the rock and from this it
can be determined if we are drilling in sandstone or shale. Oil or gas
is found in sandstone. A resistivity tool measures the natural
resistivity of the rock which is really measuring the resistivity of the
fluid in the pores of the rock. Low resistivity is water and high
resistivity means oil or gas. So now we can see if we are drilling in
sandstone or not and if the sandstone contains oil. The third most
common type are the nuclear tools. Radioactive sources are put in the
pipe which bombard the formation with gamma radiation and neutron
radiation. Without going into detail, from this measurement the density
of the rock can be determined from which can be determined the porosity
of the rock. Porosity means how big the pores of the rock. The higher
the porosity the bigger the pore are and the more fluid that is in the
pores. Hopefully this fluid is oil or gas. In summary from these first
three formation evaluation measurements we can determine if we are
drilling in sandstone or not, containing oil or not and form the
porosity how much oil is there.
Introduction
This is the first post of this log. I am an oil field worker and plan to write about my experiences. I have been in this job for the last 27 years and as my job is a little unusual I thought it might be interesting for others to read about it. I will remain anonymous, for reasons that some information may be sensitive. Likewise I will not reveal who I work for, or the client oil companies. I generally work on a rotation, meaning that I travel to a rig-site, work for a period of time, usually 3 or 4 weeks at a time and then travel home and spend an equal time at home. The equal time at home is not always equal time depending on how busy my company is. My company is a major international oil-field service company, meaning that we provide drilling related services to the client oil company.

What's all this fuss
I guess I will start writing a blog. I first discovered blogs two days ago, when it was reported that Gomery Inquiry testimony was published in a US blog. Every since I have been reading blogs and some how found other people's mundane ramblings entertaining. Almost like the TV reality shows. I can't image why one would want to read about my day to day life, but hey here goes.
I am at work right now. I have been at work for two weeks. 24/7. For the past one week I have done nearly nothing work related. I have maybe talked to the office once for five minutes. I have sent in my morning report daily which takes up about five minutes each day. And I suppose I have reset the computer about one or two times a day which takes fifteen seconds. The rest of the time I have been surfing the internet, listening to internet radio and doing e-mails. I have another two weeks of this. In a few days time we may start up operations again, in which case I will have work to do.
I am working generally from 6 pm to morning so I watch great sunrises across the water out of my window. I have a fantastic ocean view.
