-
This paper evaluates the effect of rapid cooling on the rock-cutting process and incorporates this effect as a component of drilling-performance optimization. -
From optimizing drilling performance to enhancing worker safety, computer vision can change how the industry works.
-
This paper analyzes the interaction of high-frequency torsional oscillations (HFTO) with lateral vibrations based on a model that accounts for the superimposed movement of whirl and HFTO at the bit.
-
This paper describes a collaborative project to analyze affected wells, identify commonalities, and optimize bit design and drilling parameters to mitigate the effects of borehole spiraling.
-
In this paper, bottomhole-assembly lateral behavior is analyzed using different types of computations, including static, dynamic, frequency-based, and time-based.
-
SponsoredTesting new drilling technology in a controlled and monitored environment before it is launched to its full extent in the field—that is what the Rijswijk Center for Sustainable Geo-energy is all about.
-
Derived from the principles of radial jet drilling, a new technology called micro-turbine drilling is developed to allow for drilling of micro-sidetracks from cased boreholes in very hard reservoir rock.
-
This paper describes an 18-month intensive continuous improvement process between an operator, a rig contractor, and bottomhole-assembly (BHA) service providers aimed at reducing BHAs per well in two Oklahoma rigs.
-
This paper discusses a full-scale drilling test rig that allows comprehensive study of the influences of bit characteristics on high-frequency torsional oscillations (HFTO) for the first time.
-
The US-based drilling contractor is buying the drilling technology company just three weeks after announcing a merger with NexTier Oilfield Solutions.
