Petroleum exploration workflow

Tue Sep 13, 2011 8:24 am

Hello everyone,

I just started in this industry, could anyone point me on the right direction on what is the first thing that you do in exploration, from the day that you receive the data to when you calculate the volume. If anyone can outline the workflow, it would really help.

Thank you
Khanyo

Khanyo,

You might have noticed the previous posted (which was removed) was spam, sorry for that. We are trying to battle spammers as much as possible, but sometimes one slips through.

To answer your question, would probably require a very thick book. "Exploration" is a very broad term and the tasks at hand require insight in available datasets, type of basin, location, politics, finance, etc...

in general, basin analysis (timing, maturation, play mapping and risking) is first, then prospect mapping, then usually more data gathering (either 2D or 3D seismic or a first wildcat well), then into appraisal stage (more data or deliniation wells), and then roughly volumetrics and development plan. During each stage risk is assessed and potential recoverabe volumes, but detail and certainty tried to be added in each stage...

hope this helped a bit, but this is a very complicated topic and I probably missed a lot of importent aspects..
