Re: RnR Oil Field Thread of Asskicking
First pic is a telescopic coil tubing rig. Basically it can drill out ports in a horizontal well casing! Since nowadays a directional drilling rig can hand write your name 6000m under the ground.....this type of rig has flex tubing that they feed down the well vertically then once it hits the bottom zone...it then starts to go horizontal and drills out ports made by fracing in those zones...sounds easy don't it?...it isn't but amazing to see get done.!

Re: RnR Oil Field Thread of Asskicking
Also it is telescopic because it has individual lubricators or basically feed housing for it to go through. You can customize as little or the full stack if needed. Follow that orange line down until you see the squarish looking thing and that is the B.O.P's or short for Blowout preventer. If you receive as kick(surge of back pressure) through the tubing or drill pipe you try to control ...well you have too because a uncontrolled kick is called ...you guessed it...A blowout.....want to know what one of those is?....remember BP in the Gulf?...exactly what they didn't have and they blew that out. I know people that have seen a blowout melt a 80 ton drilling rig in 20 minutes....the scariest shit essentially anyone can face in the oil industry is a complete loss of control!

Re: RnR Oil Field Thread of Asskicking
two pics below that is extendable coil tubing unit...used mostly for fracing not port drilling. That is much more heavy duty and uses the same system to drop some tubing and what is called a cup. It looks like a egg essentially at the tip of the tubing. You feed that down the well....they engage the bottom cup and it lodges into to sides of the well casing. They pressure test it to make sure it stays then they pull up on the tubing a slight amount seperating the cups. If they have good pressure containment in that area they fire hard ceramic balls into the side of the well casing. They then pump sand in at around 3500 psi to fracture the surrounding area for those newly ported holes. They then pump it full of acid or water........disengage the bottom cup and pull it to the new port tpo fire into all the while trapping that pressure in the port and zone they just Frac'd.....you work your way up zone after zone creating port after port. Sometimes near the surface or in harder formation areas they pump liquid nitrogen down the hole or if it is really deep then liquid propane. once your done all that...you get the crews out there and my job begins again as I watch over the flowing of the well. It has basically been like a karate master breaking a stack of boards how they all break and dip to a v in the middle. With all the water pumped in their the oil slides to the center and then floats to the top of the water where it can be extracted.....sometimes at that stage you need a pump jack installed to get it out...sometimes you need to swab which will bring us to the next pic and explination!

Re: RnR Oil Field Thread of Asskicking
Fracing is done at very deep depths man. Where the water formations and wells are usually fairly shallow compared to what you are trying to frac. I have never known off any surrounding area residential areas having their water contaminated...as their is a lot of code and procedure requirements in Canada to Frac. I will admit though if it is done without care to the earth or water wells in mind...it can fuck shit right up. Here in Alberta we are at the forefront of Oil extraction research and development. The industry leader research firm is located in part in Edmonton and in Leduc. I know this to be true and no ego at all involved....we lead the world in the technology and process. Problem is we don't do every job...a lot of other companies from other countries also frac that don't possess the knowledge, experience, the technology and equipment or the amount of care we put into safety for the worker or the formations and just engage rig running...when frac'ing is rushed or done complacently.....it can be disastrous.
