PRESSURE PREDICTION AND UNDERBALANCED DRILLING IN THE DEEPWATER NIGER DELTA [PDF]

, 2012
The mechanisms that cause overpressure can be broadly classified into two categories: loading and unloading. This study looks at eight wells from the deepwater Niger Delta; the wells were evaluated with three aims in mind. The first aim was to determine

A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

Advanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced
