The bankruptcy would not automatically cause your lease to terminate if the well continued to produce and was subsequently acquired by a new operator which continued operations. If the well ceased to produce after the bankruptcy filing, then your lease would terminate depending on all its provisions. If the OCC is like the RRC, the shut-in status will only be updated based on the filing by the operator. That filing will not happen if the bankrupt operator has ceased all activity, as opposed to an operator who continues to take care of the wells until they are sold or the company emerges from bankruptcy. I do not know the status definitions in OK. In Texas, a well that is shut-in means that the valves have been simply turned off and it could return to operations at any time. A well will be listed as temporarily abandoned means there is a partial plug and more work is needed to bring it back into production.
