Laminated mudstone core. Original label: Core: 7000 Spraberry sand with thin laminae of shale, showing typical vertical fracture system; Wells come in for approx. 400 b/d after hydrotracing (?), then fall off to approx 100 b/d after a month or so, but still flowing. Wells untreated would not even make lo-grade pumpers. J.O. Tomkins. 3-3-1952. |
