Drilling
Developing the theory of mechanical specific energy from the perspective of instantaneous drilling power rather than the compressive strength of the formation leads to an improved understanding of drill-bit mechanical efficiency.
The oilfield service company will supply power plants capable of electrifying 180,000 US homes with geothermal energy.
This paper presents an efficient mathematical optimization method for well placement that maximizes contact with the productive zones for the best locations in the reservoir.
-
What is observed when an unconventional well is fractured is often at odds with what was expected by those who planned the job. -
The Shearwater field is a deep, high-pressure/high-temperature (HP/HT) reservoir located in the UK Central Graben of the North Sea.
-
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.
-
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.

This paper discusses the first multilateral well with a Level-4 junction combined with an inflow-control device (ICD) planned, designed, and drilled in the Upper Burgan reservoir of Raudhatain field, north Kuwait.
