Abstract
Water entry detection into oil and gas wells has been a challenging problem to solve. This challenge is almost always present in wells of mature fields, where the paths to water entry are facilitated by changes in the wellbore and near-wellbore region. Proper diagnosis of these water paths into the production stream becomes of paramount importance in an economic environment of low commodity prices.
The use of circumferential array production logging tools can helpidentify the point of water entry; other methods commonly used are pulsed neutron technology, in oxygen activation mode, and temperature surveys. Of particular interest is a new acoustic conformance tool which can provide maps of frequency and amplitude radially around the wellbore. Whereas some of the 4 methods mentioned above are dynamic, others are pseudo-dynamic and/or static. At the same time, some of the methods are limited to the first tubular whereas others are not. This redundancy or complementary aspects of the measurements allow us to create an integrated approach with the use of multiple sensors and multiple tools to detect water entry into the near wellbore region and then into the production stream, hence reducing the uncertainty of the determination of the water path.
Speaker Biography
Dr. LUIS F QUINTERO is Halliburton’s Formation and Reservoir Solutions, Global Advisor – Production Management, and is the current President-Elect of the Society of Petrophysicists and Well Log Analysts (SPWLA). Prior to joining Halliburton, he worked as president and technical leader of Oilfield Development Specialists (ODS). He obtained a B.S. in Electronic Engineering from Universidad Simon Bolivar (Venezuela), and M.Sc. and Ph.D. degrees in Petroleum Engineering from Louisiana State University.
Luis started his career in 1984 as a wireline engineer in India (offshore and onshore). He later advanced to positions in petrophysics, reservoir engineering, business development, financial analysis, project management and production management. He has been responsible for reservoir optimization plans for fields in Colombia, Guatemala, Kazakhstan, Uzbekistan, Turkmenistan, Azerbaijan, Turkey, Bulgaria, Romania, Hungary, and Poland. Luis was also the lead for production/reservoir evaluations, operations support, and training for fields/clients in Ukraine, Bahamas, USA (Texas), Libya, Colombia, Indonesia, South Africa and India.
Dr. Quintero was previously SPWLA’s Vice-President Technology and the recipient of the Medal of Honor for Career Services of SPWLA. He has more than 25 technical publications on a wide range of topics, from the use of dielectric logs in thin beds, to NMR in carbonates, to cased hole logging (Production logging, Pulsed Neutron). Luis also is the author of 11 patents.

From the Editor
Dominic Holmes
You may have noticed a change in this month's newsletter email format. I have switched to distributing the email using MailChimp instead of mass emailing the entire membership myself, which will hopefully avoid triggering as many email spam filters. The change required using a somewhat different layout than I have used in the past, but I think overall it's a clean look and will serve the society well. And a bonus is that the newsletters should now be mobile device friendly.
Please email me if you have any trouble with the new format or have any comments or suggestions.

From the President
Suzanne Heskin
As spring arrives (or it's supposed to at least), I hope everyone is ready and excited for the upcoming workshop. This spring's workshop is focused on a specific play, which should be nice, a change from the previous few that were focused more on techniques and technologies. The Wolfcamp-Spraberry is something many of us have worked with at some point, and should be of interest to everyone. I hope you can all make it, as Bob has certainly lined up a great group of speakers.
If anyone is interested in helping out on the board next year, I'm sure we can find something for you to do or help out with. Just let us know!
