Drilling
The authors of this paper describe a method of stimulating a multizone hydrocarbon-producing well wherein a tool is deployed downhole by wireline to generate acid vapor at a target depth, allowing each interval to be treated uniquely.
The company’s new Retina imaging system creates high-resolution borehole images at the drill bit.

Altitude Energy Partners optimized drilling efficiency by minimizing dysfunctions and protecting downhole components. Their directional drilling team ensured consistent curves and laterals through precise BHA design, modeling, and trajectory control—reducing nonproductive time and drilling costs, and achieving a 100% improvement in efficiency by pad completion.

Citing impacts from COVID-19, Noble Corp. is entering into a prearranged agreement with its bondholders that will give it a fresh start with a new line of credit. -
A well was drilled into a prospective unconventional mudstone play offshore Norway. Two of five coring runs were successful while the rest yielded little to no core recovery. Subsequent investigation of the core substantiated that the coring issues largely had natural causes.

An intelligent drilling optimization application performs as an adaptive autodriller. In the Marcellus Shale, ROP improved 61% and 39% and drilling performance, measured as hours on bottom, improved 25%.

Logging-while-drilling remote operations has hit a wall. Since the outbreak of COVID-19, there is an increased demand for personnel with multidisciplinary skill sets to work on offshore rigs. But the demand cannot be satiated.

The complete paper discusses the use of cumulative production ratio curves normalized to a given reference volume in time for different unconventional plays in North America to investigate the median trend for each play and the median ultimate recovery per play.

In tectonically influenced regions, potential hydrocarbon traps are subject to complex states of stress. This scenario often translates into severe strike/slip (SS) and thrust-fault or reverse-fault (TF/RF) stress states.
