Drilling
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.

The two companies have agreed to team up so their most-valued drilling-automation programs can be used together easily. The relationship has shined a bright light on drilling automation. -
Offline cementing was used to develop a marginal field in Malaysia. The development was made possible through distinctive wellhead technology and good operational planning.

Fluid identification, a critical process in fluid sampling, continues to be a challenge in temperatures above 350°F. At temperatures up to 450°F, fluid identification is currently achieved by bubblepoint and compressibility measurements, which cannot quantitatively measure contamination levels of the sample fluid. A possible solution involves using pyroelectric detect…
