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.

Larger-diameter coiled tubing recently has been used to perform millouts because of its improved set-down force and increased annular velocities for cleanout purposes. Service companies and operators have reduced the number of wiper trips when using larger-diameter CT, to save time and money.

Carbon dioxide (CO2) with 30% foam quality (FQ) has been introduced for the first time during acid fracturing treatments in a tight, sour, high-pressure/high-temperature carbonate gas reservoir in Saudi Arabia.

This paper presents experimental and field-case studies with a sandstone-acidizing treatment designed to retard the hydrofluoric acid reaction rate and enable single-stage treatment.

This paper studied three residual-free fluid systems for acid treatments and fracturing in order to develop no-damage or reduced-damage and highly effective stimulation techniques for long-interval wells.

Challenging environments such as unstable clay formations represent high operational risk when running tubulars after drilling is completed.

A 2-year comprehensive effort to design, test, manufacture, and deploy a new high-pressure completion tubular for Chevron’s deepwater Gulf of Mexico (GOM) operations is presented.

A real-time method is presented to predict impending stuck pipe with sufficient warning to prevent it. The new method uses automated analysis of real-time modeling coupled with real-time-data analysis.

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.
