Drilling
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.
This case study from ARC Resources and DarkVision outlines the use of acoustic imaging tools in two active fracturing programs in Canada to monitor well casing deformation.
Adequate consideration must be given to the potential effect of each fluid on the successive phase operations to ensure integrated well-fluids system management.

To accelerate learning, an operator deployed a real-time, closed-loop downhole automation system (DHAS) in conjunction with wired drillpipe in the 8¾-in.-hole section. -
This paper presents the LCDSS and elaborates on the use of it in the preparation and training phase and the operational phase, including forecasting.

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.

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.
