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.

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.

The first in what is expected to be a series of compendia focused on cutting-edge research and field experiences in health, safety, security, environment, and social responsibility (HSSE-SR) is now available for free download from SPE. The goal behind this collection is to offer readers a cross-section of technical papers presented around the world at various flagship…

SPE’s Board of Directors has created a new Completions technical discipline, concluding that the interests of SPE professional members from the drilling and completions, and production and operations communities would be best served if completions became a separate technical discipline.
