As a summer intern for a small Kansas-based exploration company, it is your task to determine the orientation of a potential reservoir sand that has been penetrated by three wells. Well 1 (at a surface elevation of 450 m above sea level) was drilled to a depth of 1200 m and encountered the top of the sand at a depth of 1000 m. Well 2 (at a surface elevation of 300 m above sea level) was located 3.5 km from Well 1 along an azimuth of 035° and found the horizon top at a depth of 110 m. Well 3 (at a surface elevation of 100 m below sea level) was located 7 km from Well 2 along an azimuth of 170° and found the reservoir at a depth of 100 m. Hint: calculate your elevation from a common reference horizon such as sea level.
