Quo Vadis

Perforating and surging techniques using very high wellbore pressures promise dramatic, cost-effective improvement in initial well productivity under the right conditions. But what are those conditions, and how do the procedures work? Leading investigators look at the basics of these new completion methods, and examine lessons learned to date from Prudhoe Bay, Alaska and the North American midcontinent.

Multipurpose Service Vessels

The oil industry's push toward greater efficiency and more integrated services is profoundly impacting marine support activities. New concepts and designs that offer an expanded range of capabilities from a single vessel rather than multiple boats and barges are rapidly transforming the face of well workover and remediation operations. This article describes how innovative approaches are solving logistics and performance problems that have challenged offshore operators and service providers for decades.
