Mineral rights will be recorded (at least in Oklahoma and Texas) and registered at the county Tax Assessors office.
All land deeds and land ownership records are located there.
As a side note, someone else may hold the "mineral rights", but whoever wants to access the minerals "MUST" negotiate access (ingress/egress) with you, the land "owner".
In the past, "slant wells" were highly illegal. These days, "directional drilling" has become the norm. So there is that. They can produce a zone directly under your home from your neighbors property.
How they determine "what" is being produced from "whom" and which "zone", I have no idea?! The big benefit is that several different formations can be produced from one well site. i.e., less surface damage for more production.
They still can't suck the oil out from under your land if they don't have the mineral rights, or your land is not part of the pool of mineral right owners that comprise the drilling unit.
In fact they have setbacks as to how close they can get to the boundaries of the drilling unit.
