seems obvious

There is nothing obvious in our business as we never get close to seeing 99% of what it is we are studying.

If there was one piece of advice I would give dumdum it would be to CLEARLY always state your assumptions and with what data you are working and what you are lacking. This way you "cover your ass" because no one will do this for you !!!!

There will always be people who will want you to answer the question "So we can say that we will get this much production if we drill this well?". Your answer should be "No, we can not "say", we can "assume" based on ....".

Then you drag in the geologist, production engineer etc. to clarify to the one wanting A NUMBER how shaky the numbers are. They probable know this already but they need someone to hang the responsibility for the decision to buy, drill, farm or what ever. They want to be able to say "Eng. Dumdum told us ..."

You learn this with TIME.

Thanks for your advice, Shakespear.. I'll remember this: "No, we can not "say", we can "assume" based on ...."
