About IARP

Introduction

The International Association of Rock Physicists (IARP) is a global professional group for rock physicists and practitioners who apply rock physics results in their work. Our mission is to advance the science of rock physics by fostering connections within the rock physics community and with professionals from diverse disciplines, including geophysics, geomechanics, rock mechanics, petrophysics, seismology, and more. Our members' interests extend beyond the fundamental (F), experimental (E), and theoretical (T) aspects of rock physics (collectively known as FET) to practical field applications and interpretations.

IARP aims to unite rock physics experts worldwide, spanning various entities—from academia, research institutes, and industries, including oil and gas, as well as renewable energy sources like geothermal, and hydrogen. IARP also supports the era of energy transition and stands alongside the community committed to ambitious climate targets, and reducing greenhouse gas emissions.

Our organization operates with a commitment to diversity, equity, and inclusion (DEI). By embracing these frameworks, our community collaboratively propels rock physics to new heights.

Awarded Honorary Membership of the Geophysical Society of Houston (GSH) in 2013 "In Recognition and Appreciation of Distinguished Contributions to the Geophysical Profession". 2013 Best Paper in The Leading Edge, Society of Exploration Geophysicists.

Sirikarn (Siri) Narongsirikul, PhD

Content Manager/ Admin

Geomechanics Specialist, ConocoPhillips

Sirikarn Narongsirikul holds a MSc degree in Petroleum Geoscience from Australian School of Petroleum, University of Adelaide and a PhD in Experimental Rock Physics and Geomechanics from University of Oslo.
She started her geoscience career with Chevron in Thailand in 2002, with subsequence expat assignments in Perth office Australia. In 2014, she joined ConocoPhillips Norway and has since worked as an SME in Overburden shale rock mechanics, rock physics and 4D seismic in the Greater Ekofisk Asset. Her current role is a Geomechanics Specialist working on 3D/4D MEM with integrated 4D time-lapse seismic. She holds technical authority on geomechanics, wellbore stability studies, pore pressure predictions, and wellbore deformations to support Ekofisk Development Asset on overburden and reservoir management, well planning, drilling and P&A operations.
