March Meeting – Cased Hole Pulsed Neutron Formation Evaluation
2nd March 2017 @ 3:30 pm - 7:00 pm CET
Generously Sponsored by Weatherford
The next meeting of the Dutch Petrophysical Society will be at the Kivi building in Den Haag on Thursday 2nd March 2017.
The theme of the meeting will be
“Cased Hole Pulsed Neutron Formation Evalulation”
At the meeting we will present two talks by Jon Musselman (Weatherford) and Hans de Koningh (Xodus Group)
System Approach for Enhanced Pulsed-Neutron Applications
Jon Musselman (Weatherford)
Through-casing formation evaluation using pulsed-neutron measurements has advanced to address many challenging environments. Relatively low porosity, multiple casing strings, complex completion hardware, and the need for very accurate fluid saturation results are a few of many situations that pose challenges for traditional capture measurements with conventional pulsed-neutron tools. These challenges can be met using a systems approach. Advanced tool hardware and instrumentation forms the foundation of the logging system, but a combination of rigorous calibration, detailed response characterization, and powerful workflows and analysis techniques are required for accurate results.
The presentation reviews one such system, with emphasis on the response characterization and summary workflows derived from characterization. These can be applied to oil and gas reservoirs in a wide range of environments.
About the Presenter
Jon Musselman is the Global Production Services Product Champion for Weatherford Wireline, currently based in Houston, and working to develop solutions to address the challenges of through-casing formation evaluation and production logging.
Jon is a Mechanical Engineering graduate of the University of Texas – Arlington who brings a total of 35 years industry experience in Wireline services. He started his career as a Field Engineer with Schlumberger in North America where he later held a number of roles in field operations, management, sales and interpretation development, primarily in the US Mid-Continent and Gulf of Mexico. He later joined Baker Hughes, taking on wireline operations and sales management positions in Europe and the US.
Jon is a long-term member of SPE and SWPLA. He has been with Weatherford since 2012.
Extended Monitoring of a Mature Field – A Case Study
Hans de Koningh (Xodus Group)
A mature gas field changed ownership after 30 years of production. The field produces from multiple fault compartments, with varying gas – water contacts and depletion mechanisms. The new owner resumed field surveillance with a large campaign including several pulsed neutron log surveys. ON interpretation of the data it was found that many of the new surveys deviated significantly and consistently from original baseline surveys. An explanation was found to explain these deviations and justify a correction so that the entire set of pulsed neutron surveys could be interpreted consistently.
Here we present a case study to illustrate the value of pulsed neutron logs, especially to those who may not be so familiar with the techniques,
About the Presenter
Hans de Koningh worked for much of his career with Shell for various operating companies; including in Assen, Aberdeen, New Plymouth (NZ) and Muscat (Oman). In 2008 he returned to The Netherlands to work in consultancy, first for (SGS) Horizon and in 2011 for the Xodus Group in his current role as Principal Petrophysicist, working on assignments varying between quicklook petrophysical analyses, Field Development Plans and CPR’s – and some cased hole log interpretation.
After the talks there will be the opportunity to socialise with fellow professionals over drinks and snacks.
Doors will open for registration and coffee at 3:30 pm and the talks will commence at 4:00 pm. The social hour will begin at 5:30pm.
Thanks to the generosity of our sponsors, attendance will again be free. However please inform us of your intention to attend before Tuesday 28th February 2017 by sending an email to firstname.lastname@example.org with your name, position and affiliation.
