Abstract
Multiple-branch wellbores and horizontal holes, when applied to deep lying ore bodies, have the potential of significantly reducing total footage drilled per acre of well pattern. In addition, horizontal holes may increase sweep efficiency. Several drilling and completion concepts are given and evaluated in this report. The evaluation shows that there is economic incentive to further develop these concepts for field application to ore bodies 1,500 ft deep.
