There is another kind of depth shift I need to incorporate. This would be a non-linear stretch and squeeze. This would be due to a logging tool having a stick and pull making curves off depth from each other. As the math is slightly harder and I don't run across this very often I omitted this update for the time being.
Below I've produced some snapshots from my test well where I depth shift the neutron porosity curve. This isn't any ground breaking new idea by any means. Just documenting new functionality.
Let's start off with my Roswell, New Mexico test well.
I added a menu for depth shifting and the first thing it does is ask which curve you would like to shift.
After I pick my curve I click my marker where I want to start shifting (orange horizontal line) and the second click is where I want to move it to (green horizontal line). In this instance I want my neutron porosity to move up 50' to be in line with the inflections from my bulk density.
I (intentionally) missed my mark and need to move my green line down some, so I merely click and drag it down the green line. My intermediate changes are seen by a grey line that is interactive with the motion of the mouse.
When I let got of the mouse button I can see the lines are just as I would like them.
My original curve is still there. The data is backed up to a new curve called NPHI_N_ORIG.
Well that's all for today folks. I hope everyone has had a pleasurable summer.
