Deepwater cementing becomes increasingly challenging as drilling operations move to greater water depths and more-remote locations.

ADMA-OPCO had integrity problems in one of its gas wells, and abandonment was the only option available to restore the integrity of the offshore multiwell jacket and revive adjacent wells.

This paper describes a gas-injection pilot that has been implemented in offshore Middle East carbonate reservoirs to assess injectivity, productivity, macroscopic-sweep efficiency, flow assurance, and operational efficiency in a field that has a long water-injection history.

Industry perceives decommissioning projects as more risky and uncertain than capital projects. Several recent decommissioning projects delivered in an immature marketplace seem to support this view.

Autonomous Robotics’ first offering is built around a rounded yellow device that looks like a little flying saucer.

Advances in modeling techniques allow quantitative prediction of long-term trends in cuttings-pile characteristics and environmental risks, providing firm direction in mitigating risks.

The operator has initiated a cyclic-steam-stimulation project in the Opal A diatomite of the Sisquoc formation on the Careaga lease in the Orcutt oil field in Santa Barbara County, California. This paper discusses steam-injection step-rate tests (SRTs) for this asset as part of its expansion.

The great majority of wells do not pollute.

P&A activities using digital slickline increase equipment, logistic, and marine-support efficiency.

The polymer-injection project in the Dalia field, one of the main fields of Block 17 in deepwater Angola, represents a world first for both surface and subsurface aspects.
