Bingy is correct, wildcats are wells that are in unproven land/tenements. This can add significant value but obviously risky, hence the name "wildcat". Horizontal wells are merely just wells that go horizontal, they can be wildcat horizontals (in unproven land/areas), or they can be regular horizontals in proven land.
I'm pretty happy to leave the decision to go horizontal/vertical with the pros who have been doing this for decades (e.g. the guys who run MAD). It is after all, why they are paid.
JM.
