I hope that I am stating this correctly. Our grandfather had a Lease (pooling) with Chevron - and that has been sold through the years - not XTO has the Lease. We have been getting checks on the pooling agreement for years. Now XTO has a lease on the property (we sold the property but kept the mineral rights) and have drilled oil on the property and this is an ALLOCATION agreement. Can you have 2 different leases on the property - one for allocation and one for pooling?
