Excellent topic and great graphic....but one cannot make the assumption that avoidance of specific parcel(s) determined the direction of this particular lateral.  

I have heard rumors about "drilling around" unleased parcels but at this point they are just that, rumors.

lettijack-

I've not seen the situation that you describe, but I can imagine it occurring. In the early days of directional drilling, some unscrupulous operators would "corner-shoot" into suspected undrained rock to gain a production/ reserve advantage. In "Rule of Capture" states, it would be up to the lessor to drill their own well to capture the reserves themselves.

 

Dog legs are measured and tracked during the drilling process, the unit of measurement is degrees per 100 ft drilled or degrees in 30 meters drilled internationally. In vertical wells, it is common to limit the DLS (dog-leg severity) to 1.5to 2 degrees/100 ft. and a maximum of 5 degrees per 100 ft in the higher angle holes. Most of the shale laterals have liners with frac sleeves run into them before completion, and if the dog-legs are too high, the liners often get hung up, making for a bad day(s) to resolve.
