Due to the current COVID-19 pandemic, JFES committees have officially decided that the 26th JFES Symposium will be held as a virtual online event.

For more detail

Call for abstract is open until 17th May 2021.

All persons involved in oil, gas, geothermal, geo-engineering industry and scientific drillings are invited to submit abstracts of papers for presenting at the symposium.

The petrophysical evaluation goes hand in hand with ambiguity of interpretation. The integration of two or more techniques is therefore frequently applied as a means of refining the evaluation. The integrated approach, for instance includes;

 Core – log integration

 Log – dynamic data (drill stem test, wireline formation test) integration

 Log – Seismic integration

 Seismic – non-seismic (Gravity, Magnetic) integration

 Seismic – remote sensing integration

Not to mention for the hydrocarbon reservoir evaluation, those approaches have been applied for monitoring natural hazards (such as earthquakes, landslides, volcanoes).

In the special session this year “Integrated Evaluation”, JFES will provide petrophysicists, geoscientists and engineers with an opportunity to share their expertise in applying integrated approach. We expect the symposium to be a platform of interaction of different disciplines, which might give the injection of different types of solutions.

SPWLA Japan chapter encourage students to participate and present. Best Student Awards will be presented to the outstanding presentation. The student awarded would be nominated for SPWLA student paper contest in the international SPWLA2022 symposium.

The 113th Chapter Meeting will be held on Tuesday, 23rd March, 2021, by online. Please see News Letter for more detail.
