Do you remember a wonderful show of oil that had to be the next great oil field? And do you remember the disappointment when the DST or completion tested all water? Well, things are changing a bit in the oil patch these days and, today, not all that news is bad. An increasing level of attention is being paid to the intervals below the oil/water contacts in many Permian Basin oilfields. And, your experience and observations could be beneficial as we try to upgrade our level of understanding of the full distribution and origins of these residual oil zones (ROZs).
The University of Texas of the Permian Basin, Melzer Consulting and several participating and sponsoring organizations submitted a proposal and were recently awarded a grant by the Research Partnership to Secure Energy for America (RPSEA) to research the origins and distributions of these ROZ intervals. One of the early milestones of our study is related to telling the ROZ story (as we currently understand it) and collecting anecdotal evidence related to the ROZs around the Basin.
A symposium to this end is now scheduled for Midland College Advanced Technology Center for Thursday, October 22. The morning session will start at 10 a.m. and involves the background work that describes what we know about the origin and nature of the ROZ intervals. A speaker from one of the six companies currently exploiting the ROZ intervals with CO2 EOR will be invited to speak at the lunch. The afternoon will be devoted to smaller sessions wherein observations from the audience will be solicited by the breakout session personnel in an attempt to gather evidence from the audience related to frustrating (water) completions, sulfur observances, tilted oil/water contacts, anomalous water chemistry and corrosion intervals.
The cost for the Symposium is free; lunch will be provided. Pre-registration is required and can be accomplished by calling Joan or Linda at the Petroleum Professional Development Center (PPDC) at 432.683.2832 or by registering online at PPDC.
