Paper Number: URTEC-2021-5063-MS
... transport/deposition within the tortuous lateral section of these wells during flowback and the production period to provide operational guidance for maximizing well productivity. Introduction Unconventional resource development continues to drill longer and longer horizontal wells, in order to further...

Paper Number: URTEC-2021-5402-MS
... 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...

... prediction of hydrate stability region, hydrate formation-deposition-dissociation behaviors and hydrate plugging risk, a hydrate plugging prevention method based on safety testing window is proposed. A case research is conducted to investigate the evolution of hydrate plugging and its prevention. Results...

Paper Number: URTEC-2019-526-MS
.... 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...

... and the complications in proppant transport and deposition. In this paper, we simulate hydraulic fracturing in the presence of natural fractures in 3D and investigate key mechanisms in successfully stimulating and propping naturally fractured reservoirs. To our knowledge this if the first time the problem has been...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 23–25, 2018
Paper Number: URTEC-2903124-MS
... 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...

... million BOE for one of the 193 inter-salt shale sequences in the Qianjiang Depression. The organic-rich black shales of the Qianjiang Formation were deposited in an inland hypersaline lacustrine basin. The Qianjiang Formation shales accumulated in an environment highly conducive to the production...

... Abstract While marine organic-rich mudstones (aka black shales) have been effectively described in recent years, developing depositional models has lagged. Without depositional models, predictability of facies and properties remains a major problem. Sequence stratigraphy provides an answer...
