... within the Cretaceous and Cenozoic intervals above the shallow allochthonous salt. Basin modeling/migration evaluations in this area indicated the possibility of hydrocarbon migration from Cretaceous source rocks into some identified closures. This evaluation is still at an early-stage, but a Cretaceous...

... The brittleness index (BI) of coalbed methane (CBM) reservoirs is an important reference data for fracturing zone selection and sweet spot prediction, and also an important parameter for CBM reservoir evaluation. Therefore, the research on the brittleness of CBM reservoirs plays a vital role...

... Geologic heterogeneity and complexity are not typically captured or represented during the site selection process for identifying suitable formations and regions for CO 2 storage and/or CO 2 -EOR. This study begins with an evaluation of key geologic variables for well documented geologic...

... To successfully define a petroleum system, adequate source rock evaluation must take place (Magoon and Dow, 1994). The feasibility of source rock screening techniques used by petroleum geochemists to characterize conventional hydrocarbon accumulations as an analogue for unconventional shale play...

Note: This paper was accepted into the Technical Program but was not presented at IMAGE 2022 in Houston, Texas. hydraulic...

... of fluids. Therefore, quantitatively evaluating gas content in tight sandstone or limestone reservoirs is an urgent problem that needs to be solved. Many scholars use acoustic, resistivity, neutron density and nuclear magnetic logging methods to evaluate gas reservoirs. In addition, pulsed neutron logging...

... and the subsalt image, even when only using WAZ streamer data. However, this approach relies on RTM images for the evaluation of model updates, which are highly susceptible to illumination issues. The recently developed FWI Imaging algorithm can bolster the approach by reducing the impact of poor illumination...

... Petrophysical evaluation is fundamental to geologic understanding of the basin, resource assessment, and development. We focus on some of the major challenges to the petrophysical evaluation of tight mudrock reservoirs, with examples from the Permian Basin. We list some major challenges...

... advancements in forward stratigraphic modeling (i.e., computational stratigraphy) provide ideal datasets to quantitatively evaluate element-scale hierarchy using high resolution, fully sampled models of deepwater fan systems. In this work, we apply an unsupervised machine learning workflow to elements...

The sand aquifers were correlated across the five wells to evaluate their thicknesses and lateral extent. Porosity, permeability, formation water resistivity, and net sand thickness were estimated across the five...

... evaluating the target. Postdrill analysis concluded that Lang Lebah has limited potential due to poor reservoir quality, small gas column, and challenging drilling conditions. Due to these reasons, it was left dormant for 25 years. In 2016, new 3D broadband seismic acquisition and megamerge reprocessing...
