Special Focus

Adding streamers to an over/under configuration can improve imaging

R. Ferber
Dual over/under configurations extend lower frequencies and help image through basalt and salt, as well as improving steep dip imaging. Triple over/under acquisition further improves data quality, especially in rough sea conditions.
Combining well log and seismic data for better reservoir characterization

K. R. Mott and V. Hunt
Interpretations from either data set alone may be incorrect.
Optimizing source repeatability in wide azimuth surveys

D. A. Hite, P. M. Fontana, B. Slopey and I. Threadgold
As these types of surveys become more common, their inherent acquisition complexity means that repeating source positions, especially for 4D uses, requires special attention.
Subsalt exploration risk in deep water

S. Shaker
The interaction between salt and sediment changes the geopressure relationships below salt, increasing drilling risk.

Features

Active vibration damper improves performance and reduces drilling costs

M. E. Wassell, M. E. Cobern, V. Saheta, A. Purwanto and M. Cepeda
The new tool improves drilling efficiency.
Cementing across salt formations

B. Simmons
Using cements of low or high salt concentration appropriately makes drilling through salt less risky.
Does wireless improve process automation?

B. Karschnia
StatoilHydro found the self-organizing wireless technology significantly improves the performance of its production facilities.
Four-blade bit helps reduce drilling time by as much as half

D. Reum, J. Dahlem and J. Pollock
The new bit also saved cost by repeatedly drilling the entire interval in one run.
North Sea testing demonstrates the benefits of multi-element swellables

G. McRobb and J. Nijhof
Lab tests and field deployment of the swellable packer design showed the technology's potential to help address waterflood challenges in offshore Valhall Field.
Novel acid diversion technique boosts production

B. Garcia, E. Soriano, W. Chacon and L. Eoff
Acid diversion using associative polymer technology yields superior results as compared with foam or in situ crosslinked acid.
Optimizing CHOPS operations

P. Collins, M. B. Dusseault, D. Dorscher and E. Kueber
High production and low risk were achieved by encouraging sand production.
Optimizing the Azeri Field asset

N. Jalilova, A. Tautiyev, M. Strathman and S. Sama
Using an advisory software package, subsystems were integrated into a model that optimized the facility to create a 3% production increase.
Production and reserves lag as world drilling grows

Our annual compilation of global drilling, production and reserves data.
Subsea hydraulic control line reliability investigated

S. T. Ellis, G. Siappas, A. Colyer and R. F. Mitchell
Developing a system-level approach helped engineers understand and resolve problem control lines, and save significant repair costs.
