...) is a frequently implemented approach. However, a significant challenge encountered during the process of injecting Carbon Dioxide (CO 2 ) or Nitrogen (N 2 ) to displace oil is the occurrence of asphaltene precipitation and deposition, which can impede production. This work is an experimental study to examine...

... faults on the thickness and properties of the reservoir was analyzed. The structural activity between the different fault systems could have affected the depositional environment and especially the conditions of preservation of organic matter (dilution). This would explain why, in wells located...

... intersects natural fractures (NF) complicating the geometry of the stimulated volume and the estimation of proppant flow and transport. The effectiveness of reservoir stimulation by hydraulic fracturing depends on flow area and proppant pack permeability; hence, proppant transport and deposition...

... matter (OM) due to the prevailing reducing conditions in the Williston Basin during the deposition of the UBS. However, redox condition during the deposition of UBS is highly debated with recent interpretations widely ranging from sub-oxic to euxinic-photic zone euxinia. These inconsistencies...

The exploration efforts started in 2014, conducting some multidisciplinary regional depositional and petroleum system studies complemented with exploration wells and the acquisition of comprehensive suites of logs, cores and pressured (sidewall) cores. The Shilaif formation was deposited in a deeper water...

... Abstract The wettability of mudrock pore spaces are subject to alteration by hydrocarbon adsorption and deposition. This alteration can lead to clay and mineral grain surfaces being altered from water-wet to oil-wet, which can significantly alter pore-scale multiphase fluid distributions which...
