Drilling
The service giant shares how its new technology can sense rock properties 50 ft ahead of the bit in horizontal wells.
This paper describes the development of a method of predicting drillstring-friction coefficient during tripping operations that can be used for early warning of stuck pipe.
This paper proposes a time-series analysis approach to build a reliable, easy-to-use tool to automatically detect stuck pipe accurately and early.
-
The operator of an offshore jackup rig in the North Sea required safe and efficient deployment of the completion string without killing the well during tripping. -
Many of us work in strong functional environments, where all too easily we can deploy solutions that have the potential for repercussions on other aspects of well design, construction, completion, and performance.
-
A pilot project carried out by Hess demonstrates how quickly automated drilling technology is able to take a rig from the bottom of the pack in terms of performance and push it to the top.

The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.
-
This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability.
-
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
-
Does formation-damage coreflooding give a good representation of damage that occurs downhole? For those of us who are actively involved in coreflooding, this is a common question to be asked.
-
As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations.
-
The work presented combines a fundamental-physics approach with field data to identify the root cause of drilling failures in Paleocene and Eocene injectite-sand intervals.
