Drilling
This guest editorial addresses the need for high-temperature directional drilling technologies as the number of rigs used to develop next-generation geothermal wells is set to rise in the coming years.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

In the Eagle Ford, an integrated approach to engineering and operations was key to optimize performance and improve understanding of the area. -
Wireline continuous coring (WCC) has been adapted from the mining industry for unconventional resources. This paper is aimed at identifying and addressing complications experienced in the use of WCC.

Precise casing-wear prediction is important for improving well integrity and longevity, while simultaneously making casing designs more cost-effective. There are no industry guidelines for casing-wear prediction. This article presents a validated predictive model.

A number of companies are pushing for alternative approaches to offshore development that seek to access marginal reservoirs. Their differing and unique ideas call for a departure from the usual playbook, but share a common goal of slashing capital costs.
-
This paper analyzes differing well-factory approaches to unconventional assets, with examples from the Wolfcamp unconventional oil play in the Permian Basin.

Anyone selling something new for offshore exploration and production has to be able to answer a simple question from customers, “How can we save some money?” For Norwegian oil companies, change is coming in many forms: steel, sensors, software, and standards.

Baker Hughes is developing a drill bit capable of auto-adjusting its depth-of-cut feature to handle dynamic drilling conditions.
-
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.
-
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.
-
Challenging environments such as unstable clay formations represent high operational risk when running tubulars after drilling is completed.
