Evolution of Residual Oil Zones (ROZ's)

in the Permian Super Basin

Robert F. Lindsay

Affiliate Professor Brigham Young University

Adjunct Professor University of Texas Permian Basin


Residual oil zones (ROZ'S) are widespread in the Permian Super Basin. ROZ'a are the result of multiple episodes of diagenetic modifications to reservoirs via recharging meteoric water into the subsurface of the Permian Super Basin.


In the Late Eocene to Early Miocene (40-16 Ma) western North America experienced uplift as the Southern Rocky Mountain Epeirogene (SRME) formed, which included the western half of the Permian Basin. Uplift created a massive meteoric recharge area that extended to the present-day Rio Grande River. Uplift of the SRME was created by intrusive igneous invasion of the crust, which in far West Texas formed the Trans Pecos Magmatic Province. Additional intrusive bodies emplaced throughout all of western North America. This massive uplift charged the subsurface with meteoric water. Recharging meteoric water heated as it passed by intrusive bodies to form hot, high pressure, high volume meteoric recharge into the subsurface through porosity fairways. Meteoric recharge had such a large head of energy that it could sweep mobile oil from structural closures, which reduced oil saturations to residual oil saturation via mother-natures-waterflood.


During the Middle to Late Miocene (16-5 Ma) meteoric recharge was reduced to a trickle as the Rio Grande rift formed, which down faulted and destroyed the massive recharge area. This resulted in cool, low pressure, low volume meteoric recharge into the subsurface from small, isolated mountain ranges. As energy dissipated due to limited meteoric recharge, previously highly swept structural closures were able to: 1) back-fill and resaturate completely; 2) partially resaturate with mobile oil; 3) not resaturate with mobile oil and remain a ROZ; or 4) resaturate with gas.


As mobile oil back-filled previously swept reservoirs the underlying ROZ slightly resaturated with some mobile oil. This scenario explains why ROZ plays exist in the Permian Basin, and why they are most common in the upper half of the ROZ.


Residual oil zones (ROZ's) form five kinds of reservoirs and potential reservoirs:


ยท Oilfield; Where a residual oil zone completely refilled (resaturated) with mobile oil

ยท Brownfield; Containing a conventional reservoir above a residual oil zone (ROZ) below

ยท Greenfield; Containing only a residual oil zone (ROZ)

ยท Greasefield; Where light end hydrocarbons have been swept away leaving heavy asphaltenes behind as a residual oil zone (ROZ)

ยท Redfield; Where a residual oil zone (ROZ) refilled (resaturated) with gas
