Describe how you would go about “collision” avoidance before you start drilling.

1. You have a new play and you need to decide if directional drilling is appropriate. You are in a situation where there are ten productive zones over a true vertical depth of 2500 feet to 8500 feet. List steps in your decision making process to decide how to best produce from some or all of these zones, now or in the future.

 

1. One potential drilling target is a shale at 7000 feet. It is 35 feet thick. You have decided to drill a horizontal well into this zone. There are vertical wells surrounding your new zone. Describe how you would go about “collision” avoidance before you start drilling.

 

1. What is the ideal direction that the horizontal part of the well from part b) would be drilled in?

 

Question 2

1. Suppose that you are in a different area that you have leased in the same play. You have leased two adjacent sections of land as shown in the sketch below. There is no drilling on these sections to date.
