Daniel,
You want your final product to look like the PDF you attached? The post is unclear on what you are aiming for.
From you post the quickest approach would be to dived your data into quarters, and then grid each quarter. That would be the initial step.
You could also use Classification (under Symbology -> Classified) to customize the classes so they only show specific value ranges. If you wanted to highlight areas with revenue higher than 10,000$/day you would place a class at 10,000 and it would dived the data into areas below 10,000 and areas greater than 10,000.
I would also look into the 2 wells that produced 120K/day in 2012, they seem out of place and don't match the wells around them. Check the data behind it and make sure it is valid.
In my experience with Oil and Gas and making maps for the Non-GIS users in the company I have learned that simplicity is the best way to help them understand your map. You have to ask if it is worth separating it into quarters when the maps you attached tell a good story.
