I agree with you guys about the sidewise as well as vertical displacement.
The anticlines under the Delaware run mostly east to west and look like
barbell....with half spheres at each end.....made by stretching a dome
formation in one or two dimensions as an earthquake fault does. But these anticlines are multiple layers stacked on top of each other.
I integrated well logs into the Triple I computer for Globe Exploration
Universal in Midland the summer I graduated HS. They were building
a subsurface stratigraphic 3D model for the Government for this
area. The data was not sophisticated enough then to delineate the
stacked shale plays in a contiguous manner across the area around
the Pecos River in Loving county, then. I was on Sharp Rig 66 (diesel/electric replacement for old Rig 66 that burned down in northeast
Brookfield) and we punched holes 27,000 to 29,000 feet depth in that area of the Haley and Wheat ranches back in the early to mid 70s. The well logs were very interesting. Electro-porosity and gamma ray/neutron logs revealed structures never seen before.
Anyway, what they are calling 'unconventional shales' now were being
revealed but we didn't really know how to interpret the data then.
BTW, it is estimated the Pecos rift extends down in some places to near Source Rock from which all hydrocarbons flow through fissures to the
trap strata. Some old leases that were drilled and produced here in the early 30s played out....but they have found upon reentering them 80 years later, some of them have RECHARGED....seeming to validate the Source Rock theory proposed by the Russians.
