The 2nd iRocks Workshop 2026
Rock Physics and Beyond: From Pore to Production
Rock physics grows only when the lab and the field meet, often and in depth. For one full day in Sumedang, the Indonesian Rock Physics Society brings researchers and practitioners together, with our lab as host.

01 · The event
A small, very technical forum, by design.
Rock physics ties together seismic geophysics, well petrophysics, and lab measurements of rocks. Without a quantitative link between elastic, electrical, and transport properties, seismic interpretation loses its physical basis and formation evaluation loses precision.
In Indonesia, this expertise is spread thin. Modelling experts sit in a few universities. Practitioners who face the real problems every day work in different companies and rarely meet in a deep technical forum. Big conferences offer a stage, but seldom the time one topic needs.
iRocks fills that gap. The format is small, technical, and mixed: 30 minutes of talk, then 30 minutes of questions, so there is time for real discussion. The 2026 edition keeps this rhythm, grows the room from 40 to 100 people, and adds a visit to the DRPRS computing lab, so industry participants can see where the papers they read are made.
This year's theme, Rock Physics and Beyond: From Pore to Production, covers that whole span. A micron-wide pore throat mapped by micro-CT sets the permeability. Permeability sets how the reservoir drains. Years later, that drainage shows up, or fails to, as a change in the 4D seismic signal. The chain is usually broken, because different people work on each link and rarely meet.
"Beyond" points in three directions that are already everyday reality.
Beyond the tools we had
Neural surrogates now approximate in seconds what pore-scale simulation took days to compute. Machine learning is entering reservoir characterisation, but its physical basis and limits of validity are rarely discussed in the open.
Beyond the scale we model
4D seismic monitoring needs rock physics to explain effects it usually ignores, such as thermal compaction under cold-water injection and fluid softening under pressure drawdown.
Beyond the fluids we know
Geologic hydrogen, carbon storage and geothermal all need rock physics for conditions that classic sandstone-and-oil correlations never covered.
02 · Programme
Four themes: method, application, and what comes next.
From how we compute, to field use, to the energy questions of the next decade.

Two hundred rock physics people, one full day.
Rock physics is narrow and highly technical, so general advertising misses it. A room of 200 people who all work in it gives a precision a conference of thousands cannot match.
