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.

A fluid technology has been developed to deposit a thin, impermeable barrier over the pores and microfractures of weak, underpressured, and otherwise troublesome formations to maintain wellbore stability and reduce formation damage. -
Finding niches that provide a competitive edge over larger operators has enabled Talos Energy to leapfrog into a powerful position with Mexico’s first offshore wildcat discovery.

In the past, most wells have been drilled using conventional methods, but the landscape is changing as economic pressures have forced the drilling industry to refocus.

Bottomhole assemblies (BHAs), as part of the drilling system, have dominating effects on the functionality and effectiveness of other system components. BHA design, usage, and monitoring must promote drilling-system compatibility, efficiency, and reliability.
-
Correct placement of the rotary-speed sweet spot of a bottomhole assembly (BHA) provides multiple benefits toward achieving the ultimate goal of drilling to section total depth in a single trip.
-
Microdoglegs are a natural effect of any vertical or directional well that can explain a wide variety of downhole problems.
-
A new fatigue-management work flow provides drillers with a tool to simulate and predict the life expectancy of bottomhole assemblies (BHAs) before fatigue causes problems.

Advancements in extended-reach drilling continue from the ExxonMobil-operated Sakhalin-1 project. The latest “super complex” horizontal well stretches 15,000 m, which partner Rosneft says is a “world record.”

Drilling in high-pressure/high-temperature conditions poses numerous challenges. Drilling fluid is subjected to extreme pressure and temperature, and its properties such as viscosity are affected strongly by pressure and temperature. Viscosity decreases with temperature and increases with pressure.
