CANCELLED. Every even-numbered year, the Permian Basin International Oil Show, Inc. brings together people from every phase of the petroleum industry. Leaders come to Odessa, Texas from every corner of the world to learn about the latest technology, the newest equipment, to transact business and renew friendships. Unlike most exhibitions, the Permian Basin International Oil Show, Inc. is a non-profit venture whose sole purpose is educational, designed to serve the oil and gas industry. Run by oilmen, its mission is unwavering and its commitment is the single most important factor in its overwhelming success.
