 | | Jumbo's Madera Leases (in Lea County, New Mexico) are located in the Madera Field, which is a well developed natural gas producing field within the prolific Delaware Basin, which is part of the more regional Permian Basin of southeastern New Mexico and west Texas. |
 | | Jumbo's first well (19/1) was drilled to a depth of 15,500 feet to test at least four of the potential zones (Atoka/Strawn Formation, the Bone Springs Limestone Formation, and the shallower Brushy Canyon Sandstone Formation), for a total drilling and completion cost of US$8.4 million. |
 | | The Morrow Formation in the area of the Jumbo Madera Leases consists of a series of fluvial-deltaic sands, silts and shales, followed by a transgressive sequence of beach and near shore sandstones and a thick sequence of deeper marine limestones and interbedded shales. |
