Correlating delineated depths of the six parasequences with age indicative biostratgraphic study Obaje, reveals respective approximate age of each parasequence. Gamma ray index, IGR 3. ANN prediction model continued ANN permeability model – Performance error – Selected permeability models – Regression analysis – Test performance error – Well-3 permeability prediction result. Rollover anticlines have developed as a result of structural alignment of sedimentary deposits with associated growth faults Merki, ; Soronnadi-Ononiwu et al. Determination of hydrocarbon saturation.
This result is in consonance with results obtained in a seismic study of Bosso Field by Nton and Adesina Flow unit characterization continued – Well correlation Fig 22 Flow unit correlation of Well-1, Well-2 and Well-3 with core interval schematic. American Association of Petroleum Geologists. The same flow unit might have consistent petrophysical and fluid properties.

Reservoir characterization of the Triassic-Jurassic succession of the Bjørnøyrenna Fault
Data collection Data source: I express my true gratitude to my supervisors: It is mainly shale with locally interbedded sandstones and siltstones. This dataset comprised a suite of open-hole geophysical well logs and key geological information for six study wells in Bosso Field.
My presentations Profile Feedback Log out.
Higher positive the GR values API units signifies shalier portions of a formation while lower values indicate the sandy portions. Reservoir A has the highest net pay of The top was delineated at average depth of 7,ft 2, This result is in consonance with results obtained in a seismic study of Bosso Field by Nton and Adesina This ensures their correlation within time-stratigraphic framework.
Sandstone, heterolithic and mudstone lithologies characterised the reservoir. Xu identified a cause-effect relationship between depositional facies and hydraulic rock types based on study done by Liu et al. Seismic attribute maps for reservoir A.

First and second cases were based on equation 2. This entails vertical delineation of the penetrated geologic formations and association of the lithologic units with depositional subenvironments.

The influence of wettability and carbon dioxide injection on hydrocarbon recovery Saif Al Sayari Martin J. Dresser Industries, Houston, Texas. This formation consists of the Lower Delta plain and records coastal barrier and fluvio marine environments representing the transitional between paralic and marine paralic facies Edeki, From the foregoing, Agbada Formation top at 7, ft 2, The weights are adjusted during training to minimize error between known output and model output.
