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:dallasspwla@yahoo.com?subject=RSVP) to receive future meeting notifications by email and for making luncheon reservations (RSVP).


Next meeting - 21 September 2017  ( 3nd Thursday )


Measuring Remaining Oil Saturation with Cased Hole Pulse Neutron Log in CO2 EOR Fields

presented by

Zhipeng “Z” Liu, P.E.  


There are about 400 billion barrels of estimated remaining oil in place. However, quantifying remaining

oil saturation has always been a critical but challenging task for petrophysicists and reservoir engineers

due to the geology, and additional complexity introduced by field history. CO2 flood is a proven EOR

method to recover some of the remaining oil in place, while the presence of CO2 poses additional

petrophysical challenges. Conventional open hole logging and coring methods remain useful, but are

limited by tool physics, wellbore, fluids, and cost. New cased hole pulse neutron logging tool and

interpretation technologies offers some promise to overcome these limitation and measure remaining

oil and gas saturation in CO2 flood fields. We will discuss the technology followed by its application in

CO2 flood fields and other mature fields.

Speaker Biography:

Zhipeng “Z” Liu, P.E. is Sr. Petrophysicist/Reservoir Engineer Kinder Morgan in Houston. He

also serves as 2017 President-Elect for SPWLA. He is a licensed Professional Petroleum

Engineer in Texas. Previously, he worked for Schlumberger, BP, and Pathfinder. He

specialized in US onshore conventional, unconventional and EOR reservoirs. He earned his

first M.S. degree in Petroleum Engineering from the University of Texas at Austin, second M.S. degree in

Petroleum Geology from the University of Houston. He is a CFA Level III candidate. He has published

more than a dozen technical papers and has been granted 3 US patents.
