Investopedia explains 'Gross Acres'
The number of gross acres a company has, tells investors something about the company's size, market position and current activity, but it does not tell the whole story. What is the company doing with that acreage? Is it drilling wells and at what pace? How many barrels of oil is the area producing and how many is it expected to produce?
Larger companies will usually have an interest in hundreds of thousands of gross acres, while smaller ones may only have an interest in tens of thousands of gross acres. The largest companies will have total holdings of millions of gross acres.
