WOG Well Optimization by Geosteering: A Pilot Software for Cooperative Modeling on Internet — IFP has recently started the development of a new data management system named WOG for “Well Optimization by Geosteering”. In this project, our aim is to distribute the information through the network so as to share knowledge. The key advantage of this software is to allow visualization for each of Int...

Quantitative workflows utilizing real-time data to constrain uncertainty have the potential significantly improve geosteering. Fast updates based on are particularly important when drilling in complex reservoirs with high uncertainties pre-drill models. However, practical assimilation of requires effective geological modelling and mathematically robust parameterization. We propose a generative ...

Horizontal drilling is an important development in the petroleum industry and it relies heavily on guiding the drill bit with the aid of sonic logging, i.e. geosteering. The quality of sonic imaging depends heavily on the effective suppression of borehole waves and enhancement of weak reflection signal. To this end, we propose an approach to image the near-borehole structure using acoustic logg...

Deep learning (DL) inversion of induction logging measurements is used in well geosteering for real-time imaging the distribution subsurface electrical conductivity. We develop a DL workflow to solve 2.5-D inverse problems arising geosteering. The employs three modules: “look-around” fault detection module and two modules reconstructing anisotropic resistivity models presence or absence planes,...

In thin-layered reservoirs, drilling engineers face tough challenges—planning their drilling programs to follow the most productive reservoir layers while avoiding nearby water, gas or high-pressure zones. The rewards for a successful drilling strategy are clear—increased oil production and reduced water cut. In an oil field in the Persian Gulf, for example, oil production was increased four- t...

Because some oilfields in China belong to the thin bottom water reservoir model, actual drilling process is technically difficult. In order ensure maximum operation of target layer and basic development effect oilfield, technicians should introduce advanced steering tools study new geosteering technology fundamentally exploitation quality oil reservoirs.After exploring introduction geological g...
