I have also opined that the farther one gets from the vertical, the less effective the production (for any number of reasons), and I predicted that we would eventually see toe-to-heel horizontals paralleling heel-to-toe horizontals. I now have a great example (and there are others).
At the NDIC GIS map server, go to section15/22 T154N-R91W. Currently there are eight wells in these two sections. The horizontals from these eight wells do not all drain sections 15/22.
The wells:
- 17080, 2,096, Whiting, Niemi 44-22H, t10/09; cum 459K 12/16;
- 18507,1,946, Whiting, Lahti 24-22H, t6/10; cum 516K 12/16;
- 19502, 2,720, Whiting, Niemitalo 31-15XH, t2/11; cum 406K 12/16;
- 20415, 362, Whiting, Laukala 34-22TFH, t9/11; cum 133K 12/16;
- 21273, 273, Whiting, Lahti 41-15TFX, t12/11; cum 123K 12/16;
- 21348, 312, Whiting, Lahti 31-15TFX, t12/11; cum 151K 12/16;
- 21438, 370, Whiting, Lahti 14-22TFH, t11/11; cum 172K 12/16;
- 21546, 537, Whiting, Lahti 12-22TFH, t3/12; cum 167K 12/16;
- 17080, 2,096, Whiting, Niemi 44-22H, t10/09; cum 459K 12/16;
- 21273, 251, Whiting, Lahti 41-15TFX, t12/11; cum 123I 12/16;
As noted above, there are eight (8) wells in these two sections; I could easily see another eight wells in these two sections (again, the horizontals would drain neighboring sections in some cases). But to the surface owner, one would see as many as 16 wells in these two sections.
