...Geosteering of Wells Strat-based and Model-based geosteering uses different techniques that utilize real-time interpretation of L/MWD (Logging/Measurement While Drilling) logs to determine the stratigraphic position of the well and the local geological model. This reduces geological...

... the injection intervals over the extended survey periods. The primary cause was fibre damage and/or breakage due to crossflow between perforated sections. While a qualitative interpretation of the injection profile was possible for most wells, the combination of crossflow and Joules-Thomson cooling combined...

... interpretations using shut-in pressure drop data guide the fine-tuning of water injection parameters. This transition shifts the water injection regime from the conventional "24-hour stable flow continuous water injection" to an "X hours injection/ 24-X hours shut-in intermittent water injection" approach...

A typical log of wells in both the K and S fields is depicted in Figure 1 (a). The BRF in these two...

... occasionally interspersed with channel formations across the shelf. Utilizing recent seismic data and attributes such as variance, impedance, and spectral decomposition, an improved understanding of horizon interpretations and fault properties, encompassing their geometry, throw, and extension, was achieved...

First, the static model was built by integrating geological understanding, well data, logging data and petrophysical interpretation, core data, and quantitative interpretation (QI) from seismic data. Then, the subsurface uncertainties were captured and transferred to dynamic model...
