xtgeoviz.plot.xsection module

Module for fast XSection plots of wells/surfaces etc, using matplotlib.

Bases: BasePlot

Class for plotting a cross-section of a well.

Parameters:

• well (Optional[Well]) – XTGeo well object.

• surfaces (Optional[list]) – List of XTGeo RegularSurface objects

• surfacenames (Optional[list]) – List of surface names (str) for legend

• cube (Optional[Cube]) – A XTGeo Cube instance

• grid (Optional[Grid]) – A XTGeo Grid instance

• gridproperty (Optional[GridProperty]) – A XTGeo GridProperty instance

• colormap (Union[str, LinearSegmentedColormap, ListedColormap, None]) – Name of colormap, e.g. ‘Set1’. Default is ‘xtgeo’

• outline (Optional[Polygons]) – XTGeo Polygons object

canvas(title=None, subtitle=None, infotext=None, figscaling=1.0)

Prepare the canvas to plot on, with title and subtitle.

Parameters:

• title (str, optional) – Title of plot.

• subtitle (str, optional) – Sub title of plot.

• infotext (str, optional) – Text to be written as info string.

• figscaling (str, optional) – Figure scaling, default is 1.0

plot_well(zonelogname='ZONELOG', facieslogname=None, perflogname=None, wellcrossings=None, wellcrossingnames=True, wellcrossingyears=False, welltrajcolor='black', welltrajwidth=6)

Input an XTGeo Well object and plot it.

set_xaxis_md(gridlines=False)

Set x-axis labels to measured depth.

plot_cube(colormap='seismic', vmin=None, vmax=None, alpha=0.7, interpolation='gaussian', sampling='nearest')

Plot a cube backdrop.

Parameters:

• colormap (ColorMap) – Name of color map (default ‘seismic’)

• vmin (float) – Minimum value in plot.

• vmax (float) –

• alpha (float) – Alpah blending number beween 0 and 1.

• interpolation (str) – Interpolation for plotting, cf. matplotlib documentation on this. Also gaussianN is allowed, where N = 1..9.

• sampling (str) – ‘nearest’ (default) or ‘trilinear’ (more precise)

Raises:

ValueError – No cube is loaded

plot_grid3d(colormap='rainbow', vmin=None, vmax=None, alpha=0.7, zinc=0.5, interpolation='auto')

Plot a sampled grid with gridproperty backdrop.

Parameters:

• colormap (ColorMap) – Name of color map (default ‘rainbow’)

• vmin (float) – Minimum value in plot.

• vmax (float) –

• alpha (float) – Alpha blending number beween 0 and 1.

• zinc (float) – Sampling vertically, default is 0.5

• interpolation (str) – Interpolation for plotting, cf. matplotlib documentation on this. “auto” uses “nearest” for discrete parameters and “antialiased” for floats.

Raises:

ValueError – No grid or gridproperty is loaded

plot_surfaces(fill=False, surfaces=None, surfacenames=None, colormap=None, onecolor=None, linewidth=1.0, linestyle='-', legend=True, legendtitle=None, fancyline=False, axisname='main', gridlines=False)

Input a surface list (ordered from top to base) , and plot them.

plot_md_data(data=None, markersize=10, color='red', linestyle='', label=False, zorder=350, **kwargs)

Plot MD vs TVD data as lines and/or markers.

The input pandas dataframe points shall have the following columns: * Name of well(s) named WELL * Coordinate X named MDEPTH * Coordinate Y named Z_TVDSS

plot_wellmap(otherwells=None, expand=1)

Plot well map as local view, optionally with nearby wells.

Parameters:

• otherwells (list of Polygons) – List of surrounding wells to plot, these wells are repr as Polygons instances, one per well.

• expand (float) – Plot axis expand factor (default is 1); larger values may be used if other wells are plotted.

plot_map()

Plot well location map as an overall view (with field outline).
