Presentation: Application of dielectric and standard logging suites to characterize stratigraphic variations in Archie parameters
Abstract: Estimation of accurate electrical property parameters, such as the
"cementation exponent" m and
"saturation exponent" n is critical for characterizing hydrocarbon saturations with resistivity based models for
completions decisions and original oil-in-place estimation. These exponents are known to vary with formation brine
salinity, clay-content, porosity, grain-size distribution, pore geometry, stress and fluid wettability. Consequently, ...

About the monthly meetings.
June 16-20, 2012 - SPWLA Symposium -
SPWLA’s 53rd Annual Symposium was be held June 16th to June 20th, 2012 at the Cartagena Convention Center in Cartagena, Colombia. The Colombian Association Formation Evaluation (CAFE) has launched the
Symposium’s official website,
which provides up-to-date information regarding the venue,
technical program details and event schedules.
Our Next Generation
Since the DWLS does not officially have a Young Members contingent, the DWLS board has decided to
support the efforts of the Next Generation of Oil and Gas Professionals (NGOGP). NGOGP is “a collaboration
of young professionals in the oil and gas industry, including geologists, geophysicists, engineers, landmen,
and accountants. We are an extension of each professional group – RMAG, DGS, SPE, DAPL, DWLS and COPAS –
coming together to facilitate interdisciplinary outreach and networking. Through a series of sponsored
events, we hope to engage and recruit an active core of young professionals who will become the next
generation of leaders in our organizations.“
Sponsoring the NGOGP for the 2012
season, as this society is solely able to function based on donations.
For more information on NGOGP please visit
their website or you can contact
Stefani Brakenhoff your
DWLS representative on the NGOGP board with any questions or to get on the mailing list.
If you do any log interpretation at all, you need to check
out the Historical Chart Books on
that has been made available by the DWLS. Special thanks to Bob
Cluff for making this possible.
Another valuable resource, made available by the Phil Nelson
of the USGS, is
A Catalog of
Porosity and Permeability from Core Plugs in Siliciclastic Rocks.
New! Even better, we have some
other goodies for sale.
