Due to the fact that the Eagle Ford Shale is rather evenly distributed throughout the trend, all acreage regardless of size is important to the operator. For the oil company to develop a successful and commercial exploration and production program in any given unit, all acreage in a direct line with any horizontal well has to be leased. The operator cannot drill under your land without committing trespass, and it quite simply is NOT feasible for them to exclude you or to drill around you.
The manner and way in which small acreage is incorporated into larger Eagle Ford Shale tracts is illustrated in a news story I found on the internet today regarding a 43.291 acre tract at http://www.investegate.co.uk/article.aspx?id=201008270820557470R and http://abnnewswire.net/press/en/63607/Texon_Petroleum_Limited_(ASX:TXN)_Equalization_Of_Leighton_Eagle_Ford_Acreage.html
