Monthly Chapter Meeting:
GREAT NEWS!! The Dallas Chapter will continue to meet in the DeGolyer & MacNaughton sponsored business conference room located in the Providence Towers building at 5001 Spring Valley Road in North Dallas. Located north of LBJ (I-635), south of Belt Line Road, and on the west side of the North Dallas Tollway, this building has the large open archway in its middle and has a red granite facade. The meeting room is located on the first floor of the East Tower. Parking is underground ($1) and can be accessed from either Spring Valley Road or from the southbound service road of the tollway.
Please RSVP early in order that enough food is ordered and that the chapter does not order too much!!
Meetings start at 11:30 for a social gathering, followed by a catered buffet at noon (cost $20, students $10).
Please contact Violeta Lujan (mailto:email@example.com?subject=RSVP) to receive future meeting notifications by email and for making luncheon reservations (RSVP).
Next meeting - 9 April 2017 ( 2nd Thursday )
ASSESSING RESERVOIR QUALITY IN TIGHT OIL PLAYS WITH THE DOWNHOLE RESERVOIR PRODUCIBILITY INDEX (RPI)
(Schlumberger-Doll Research Center)
Reservoir quality (RQ) of unconventional resources is influenced by the amount and type of organic matter in the formation. In gas-bearing shales, gas is typically stored and transported through organic pores in kerogen—thus, high quantity of kerogen typically leads to higher porosity/permeability and is considered a positive RQ indicator. In oil-bearing shales, mineral-hosted pores contribute significantly to hydrocarbon storage and transport, while kerogen and bitumen can trap fluids by adsorption and blocking pores—thus, high quantity of kerogen and bitumen can be
considered a negative RQ indicator, emphasizing the need to differentiate types of organic matter in tight-oil formation evaluation. Here we present reservoir producibility index (RPI) for assessing tight-oil RQ using exclusively downhole logs. The index differentiates oil from kerogen and bitumen as being, respectively, positive and negative RQ indicators. The utility of the RPI is demonstrated in several examples, wherein zones identified as having the best RQ are found to be the most productive.

Paul Craddock is a Research Scientist at Schlumberger-Doll Research Center in Cambridge, Massachusetts, USA. His research focuses on development of methods for oilfield formation evaluation from logs, core, and cuttings. These methods include infrared, X-ray, and nuclear spectroscopic methods applied in particular to the characterization of formation mineralogy, whole-rock inorganic geochemistry, and kerogen composition in shale.
Current applications of this research include derivation of more accurate formation matrix properties and fluid properties for enhanced petrophysical interpretations of shales. Paul received a PhD in chemical oceanography from Massachusetts Institute of Technology/Woods Hole Oceanographic Institution in 2009. Prior to joining Schlumberger in 2011, Paul was a postdoctoral scientist at University of Chicago studying metal isotope systematics in Earth and planetary materials. He is a member of SPWLA and SPE.
