|
|
After doing the site preparation what is the next step? |

What 3 things are needed for the Drilling Rig |
-Surface hole -Surface casing Installation -Blow-Out Preventer (BOP) |
|
|
Surface Hole |
60-400m deep hole, depending on conditions of the area. Drilling rig is set up on top |
|
|
Surface Casing Installation And what it does |
Steel pipe inserted and fixed in place with cement. -controls the return flow of mud and drilling fluids -is lores the wellbore from surroundings -prevents ground water contamination |
|
