# GEOSCIENCES & RESERVOIR

GEOPHYSICS & GEOLOGY

▪ Data acquisition: low-cost & HRes fiber optic systems (surface & subsurface – 3D/4D)
▪ Data imaging: real-time QC and Processing/Migration
▪ Non-seismic: absolute gravimeter
▪ QC/QA: semi-automated methods (AI/ML) to select quality & relevant G&G data among huge datasets and accelerate turnaround of value chain (particularly the mob-demob of data)
▪ CCS:
- Prediction & modeling of induced seismicity for risk assessment
- Geophysical characterization of seal/overburden
- Geohazards characterization with leaking risk assessment
- CO2 storage in basaltic rocks (assessment, characterization, PVT modeling…)
- CO2 storage in Deep & Cold Sea → CO2 hydrates creation

RESERVOIR MODEL BUILDING
▪ AI/ML: with workflows automation (from well correlation & calibration to reservoir static modeling dynamic and to dynamic simulation)
▪ Use of Geophysics properties to derive pseudo-geological properties to infill reservoir model
▪ CCS model building with:
- Unstructured meshes for grid building for CCS
- Geo-mechanical constraints

# DRILLING
▪ For High Temperature Geothermy (from 250°C to 450°C)
▪ In Basaltic rocks (from cold temp. to high temp.) with innovative cement and steel materials
▪ Microwaves technology
▪ Innovative LWD tools @ HT
▪ Measurements in Basalts: acidity, PH, composition of fluids, metals composition (Mg, Li, Ni, Ch, Co…)

CCUS is today a key lever identified for many industries to reach a net zero target in 2050. As an hard to abate sector, cement industry is engaged to reach these goals and fully involved in CCUS today activities. Holcim group targets for example a mean value of 475kgCO2/t cementitious materials in 2030, towards 576 KgCO2/t cementitious in 2018. This already significant reduction is based on traditional levers already know by cement industry. CCUS is expected to further reduce this footprint from 2030 to 2050.

CO2 mineral carbonation is one of the levers explored today by construction industry because it could represent a permanent CO2 storage and a possible way to minimize gas purification for its use (low grade CO2 could be used). Mineral carbonation can be divided in two families: ex-situ and in-situ, presenting both pros and cons:
− In-situ mineralization represents long term and safe CO2 storage underground. When the situation is favorable to it (underground geologic layers available), significant volumes could be stored.
− Ex-situ CO2 mineralization enables to store certainly less volumes, but offers the possibility to valorize the final carbonated product in cement and concrete applications.

Many worldwide start-ups and universities labs are already working on the subject today. The technical and economic viability of these solutions has still to be proven and optimized. For example, carbonation processes still need upscale and energy requirements optimization to render them more attractive, norms limit today the final use of the carbonated products, the CO2 ETS system does not yet allow to deduce the CO2 trapped and stored by mineral carbonation from the emissions…

These barriers will certainly be modified in a near future; therefore any novelty in this domain would be of interest for cement and concrete industry at least.
