Lease question

I signed an extension of a lease in May with Anadarko and now have received an offer for another lease from another company. This confuses me...can one hold more than one lease on the same land? Section 9, block 2. Thanks for any objective information.

Do either lease offers state to cover the whole section, or just a certain part? There should be a legal description on both lease offers, and they should either specify a certain part, as in the West 100 acres, or the S/2 (south half), or something to that effect - if it doesn't specify a certain part, then it is meant to cover the whole section. Second, do either leases specify the depths that they intend to cover?

Review and compare the full description that was on the lease vs what the 2nd group wants to lease like Snelson suggests above. It is also possible that Anadarko hasn't gotten around to recording your lease yet which brings up an interesting question. Have you been paid for your extension yet? If you've been paid and the description is the same, you need to sit still. If you haven't and description is the same, you have a whole different ball game to play.
