Mineral rights questions

I own the mineral rights on my property. My rights along with 8 other property owners are part of an existing lease that has one old gas well producing. There is much new drilling and production here now and currently there is drilling on the quarter section that my proprty is in. There are four directional wells permited, three have unit acreage of 160, the other has unit acreage of 320. Do I have rights to these wells, and what about the other members in my lease?
