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.

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 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.

The Loma Alta Sur (LAS) field is a multilayer fluvial sandstone reservoir in the Neuquén basin of Argentina. Colloidal-dispersion-gel injection was considered a viable strategy to improve oil recovery in the field after early water breakthrough.

The coiled-tubing industry is adapting to the changing environment. The next 12 months could bring greater or lesser volatility but the coiled-tubing industry’s record last year indicates that it will still be moving forward.

While there is increased scrutiny from regulatory and community stakeholders on the chemicals used in operations, complex and technically challenging reservoirs must be developed to replace reserves. Matrix stimulation remains a critical technology for delivering barrels at minimum cost.

No matter how technically impressive or innovative a technology is, if it is not operationally practical and cost-efficient, then it is just a cute widget. The Wellbore Tubulars section papers focus on delivering efficiencies, converting nonproductive time into new dollars for the bottom line.

Since 2006, production from gas injection has outstripped that from thermal, and is continuing to grow. Even though industry conditions remain tough, EOR is expected to be increasingly important in the future, with the possibility of  further uptake of it linked to the climate-change agenda.

This paper details the planning, design, and execution of a project involving the core drilling of three wellbores using coiled-tubing directional drilling along the future Rogfast tunnel route on the Norwegian coast.

The installation of flowlines in ever-deeper and -more-remote areas requires specific technologies for precommissioning. Coiled tubing can be a solution, but long durations may affect tubing stress and fatigue.
