SP log temperature and mud resistivity were known Sw determination Tools: Formation Average thickness ft Benin 7, 2, Facies analysis is important in the investigation of wells and their log information. In order to properly characterize the reservoir sands delineated and correlated across the studied wells, a plot of versus i. Calculations for clay volume, porosity, permeability and water saturation were performed. Most northerly minor faults are synthetic to the major fault M2; those at the central parts are antithetic.
American of Association of Petroleum Geologists Bulletin, 62, This dataset comprised a suite of open-hole geophysical well logs and key geological information for six study wells in Bosso Field. Structural Geology of the Cenozoic Niger Delta: SP log temperature and mud resistivity were known Sw determination Tools: Sequence Stratigraphy Concepts and Applications:
Correlation and modelling was done for layers cutting across the six wells. Introduction to Wireline Log Investigation. Average gross thickness of the reservoirs estimated was 27 m with average values of porosity and permeability as 0.
Lawrence,and HaykinIt is not suitable if the solution exists. All the hydrocarbon bearing reservoirs show excellent permeability, ranging from 1, Table 1 Measurement of formation Formation Measurement Parameters Electrical resistivity – Bulk density – Natural and induced radioactivity – Hydrogen content – Travel time of sonic wave Porosity primary and secondary – Permeability – Fluid saturation – Hydrocarbon type – Lithology – Formation dip and structure – Sedimentary environment – Elastic modulus Fig 10 Well logging measurement.
Integration of Seismic and Petrophysics to Characterize Reservoirs in “ALA” Oil Field, Niger Delta
The plot revealed that the sands reduced in thickness going from west to east. Pham Huy Giao Chairman: Sedimentologic study of shale-sand series from well logs.
Average thickness of sand A is Shale and siltstone Reservoir rock: Share buttons are a little bit lower. On the Rms amplitude attribute map Figure 8 bclosure 1 has moderate amplitude ranging from 20 to 53 while closure 2 has amplitude as high as Alternation of equal proportions of sand and shale units in makes its lower portion.
Gas fields, Malay basin, Gulf of Thailand Data: Sw output is ordinarily taken as water saturation of the effective porosity. Hence, the physical properties of reservoir rocks found in this formation are often dependent on the fluids in the pores. The study will reveal any existing isolated reservoirs and guide the design of directional drilling to optimally drain their hydrocarbon content. ANN training and testing with data sets from all available data, data selected from interpreted reservoir zone and data from flow unit characterization.
Pwtrophysics on the ANN methods and its application in parameter prediction based on the well logging data. North Malay basin characteristics Depth: Sandstone Fig 7 Malay Basin province Michele, Data collection Data source: How well would we be able to foresee penetrability in sedimentary basins?
The case study for this cause-effect relationship was on a formation of sandstone unit deposited in a deltaic sedimentary system in the Columbus Basin, offshore Trinidad.
Reservoir characterization of the Triassic-Jurassic succession of the Bjørnøyrenna Fault
These stratigraphic units can be classified as topset beds, foresets and bottomset beds. It is however expected that the early Pliocene directly overlies the late Miocene, in relation to past palynostratigraphic study Aturamu et al.
Flow unit characterization continued – FZI determination Fig 18 Flow unit characterization of all core interval in Well Petrophysics and rock modeling of diagenetically modified sandstone. A parasequence is typically characterised and recognised from different parasequences utilising flooding surfaces.

They will produce only water. Average thickness of sand B was ft The ANN for permeability and porosity prediction was constructed and used to predict permeability and pterophysics from well logging in the study area. This third generation reservoir made significant use of 3D seismic amplitude anomalies and other complex trace attributes to define field development programs.
Lawrence,and HaykinIt is not suitable if the solution exists.
The careful interpretation of geological processes capturing by well log data will lead to quantify reservoir qualities that linked to depositional footprints and diagenetic processes. Fig 1 Application of ANN of well logging.
