Synthetic

Some preliminaries...

Load a well from LAS

Use the from_las() method to load a well by passing a filename as a str.

This is really just a wrapper for lasio but instantiates a Header, Curves, etc.

from welly import Well



In [3]:

    
w = Well.from_las('P-129_out.LAS')

Add a synthetic

The make_synthetic() method assumes that the DT log is called 'DT' and has units of µs/m, and the RHOB log is called 'RHOB' and has units of kg/m³. Our logs have the right names, but the wrong units, so let's adjust them:



In [4]:

    
w.data['DT'] = w.data['DT'].extrapolate() / 0.3048
w.data['RHOB'] = 1000 * w.data['RHOB']



In [5]:

    
w.make_synthetic(srd=100)



In [6]:

    
s = w.data['Synthetic']
s.plot()
