A Warranty Deed Conveying Oil, Gas, and Minerals is a legal document that is used to transfer a seller’s interest in oil, gas, and/or minerals to a buyer. It is an assurance deed which means that the seller guarantees that the title is good and that the buyer will have clear title to the oil, gas, and minerals. This type of deed conveys ownership of the oil, gas, and minerals to the buyer with no encumbrances. There are two types of Warranty Deeds Conveying Oil, Gas, and Minerals: an ordinary warranty deed and a special warranty deed. An ordinary warranty deed conveys the seller’s interest in the oil, gas, and minerals but does not guarantee that there are no third-party claims or encumbrances to the property. A special warranty deed conveys the seller’s interest in the oil, gas, and minerals and also guarantees that the seller has not sold the same interest to any other party and that the title is clear of any encumbrances.
