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:firstname.lastname@example.org?subject=RSVP) to receive future meeting notifications by email and for making luncheon reservations (RSVP).
Next meeting - 11 May 2017 ( 2nd Thursday )
Petrophysical Cut Off Definition Based on Dynamic Reservoir Parameters
Serge V Galley
use cut-offs for calculation of average values that are often part of STOIIP
and reserve computations. Generally these cutoff parameters are not rigorously
defined. Cutoffs are most commonly based on static parameters like
porosity, saturation and shale content. These may be based on local knowledge
about reservoir performance, or might simply be used because “it has always has
been done that way”. Of interest here are static and dynamic cutoff parameters
that will affect the assessment of pay. The authors propose a workflow
based on application of saturation-height calculations, combined with
fractional flow computations, to estimate initial water cut. The
saturation-height calculations utilize property-based Techlog capillary
pressure models, and the fractional flow calculations link this through a
Python Script to the relative permeability models used by the reservoir
engineer. This provides a consistent way to introduce a dynamic element to a
pay cutoff definition – for instance by requiring pay to produce only dry oil or
requiring pay to be defined as having a minimum initial water cut. There
are numerous parameters which can characterize subsurface rocks and fluids but
essentially all of them are directed at one purpose, which is to provide an
answer to one question, will this well be economical? The proposed tool allows
petrophysicist to help answer this question.
Serge V. Galley is a Petrophysicist, a member
of SPWLA and a registered Geoscientist of APEGA. He started his career as logging
engineer and petrophysicist in various entities of USSR Ministry of Oil. He received his PhD in 1991 at SoyuzPromGeophysics Institute in Russia. Since that
time he has worked as Operational Manager of Western Atlas and VP of American
International Petroleum Corporation, responsible for planning and conducting
exploration strategy, managing drilling, seismic, logging, testing and
production operations and later became Head of G&G Department of Caspian Gas
Corporation and Geoscientist for ODS Company. Since 2007 he is a Senior Petrophysicist
working for Shell in Houston with his main area of interest being thin bed, low
resistivity (TBLR) pay characterization.
