The methodology is implemented by a careful estimation of the Total Dissolved Solids (TDS) typically found in formation waters. Wireline formation testing and sampling tools are used to collect downhole samples, and to monitor cleanup...

... Abstract Modern seismic acquisition is trending toward recording high-channel count data with smaller field arrays or single sensors. Reducing the size of field arrays leads to a deterioration of data quality. Many processing steps requiring estimation of prestack parameters become more...

... that connect the wellbore to a larger fracture surface area within the reservoir rock volume. Thus, accurate estimation of the stimulated reservoir volume (SRV) becomes critical for the reservoir performance simulation and production analysis. Micro-seismic events (MS) have been commonly used as a proxy to map...

... drilling motors combined with delayed logging tools, and insufficient data to quantify mechanical properties while drilling created multiple geosteering challenges. This paper describes a new technology that uses surface drilling data to estimate, in real time, the geomechanical properties needed to guide...

... Where TOC is the total organic carbon, ρB is the formation density in absence of organic matter (g/cm 3 ), p is the formation bulk density (g/cm 3 ). ΔlogR method was proposed by Passay et al. (1990) which is now the most popular method for estimating the TOC. The availability of organic rich rock...

... Abstract Accurately estimating the fluid distribution in the reservoir is a key challenge in the oil industry. Well-log measurements are used to quantitatively characterize subsurface properties such as porosity and fluid saturation. It was proven that it is possible to reduce the ambiguity...
