Youtube video 20 px icon  13:31 min.    The GeolOil log-plot display panel

A left button click reads the actual curve values at its measured depth MD. The center button places a vertical reference base-line. Drag the right button measures vertical zones thicknesses.

It also shows how to put besides the MD scale, a depth scale with TVD, TVD-SS, and INC, write text annotations on the tracks, and put marks using keyboard short-cuts.

Youtube video 20 px icon  35:20 min.    Petrophysical Summaries and well log Upscalings

This video starts showing how to define and plot flag curves for reservoir and pay rocks. Then, classical summaries like net-sand, net-pay, and Net-To-Gross NTG are illustrated on two wells analyzed. Finally, the video shows how to compute upscaling summaries for porosity, water saturation, and permeability on each stratigraphic zone.

Youtube video 20 px icon  16:46 min.    Defining petrophysical work-flows

This video shows how to define a sequential work-flow of petrophysical functions.

Although each well may have its individual interpretation work-flow procedure, some elements are usually common, like calculate the borehole temperature, the formation water resistivity Rw that depends upon temperature, etc.

Youtube video 20 px icon  18:46 min.    Water analysis, salinity, and Rw

This video teaches how to estimate water salinity and Rw formation water resistivity from water analyses, core SW data, and log data.

Log data techniques introduces an improvement of the Hingle and Pickett-Plot equations to deal with shaly sands through extensions of the apparent water resistivity Rwa applied on water bodies like aquifers and water pockets.

Youtube video 20 px icon  16:09 min.    Fuzzy-Logic Mineral Solvers

A clastic reservoir is analyzed to detect its main clay minerals. The results are compared with X-Ray-Diffraction (XRD) and a reasonable match is found.

A well with a carbonate zone, and an eolian sand zone, is studied. Mineral proportions of clays, silt, quartz, calcite, and dolomite, are found.

A well with a tight zone and a shale oil zone is studied. A good quantitative match with the mineral proportions from lab XRD is found.

Youtube video 20 px icon  61:49 min.    Multi-Zone variable parameters

This video shows how to define non constants petrophysical parameters per zone. In GeolOil any parameter can be defined either as a constant, or a full regular variable curve.

The video presents a full case study with several zones. Each zone has its own different salinity, and therefore its own internal Rw variable curve per zone.

GeolOil introduces its exclusive Trilean Logic Engine to handle stratigraphy uncertainty, nested stratigraphic members inside formations, and its relationships with user defined defaults.
