Overview of Cantarell field development program offshore Mexico

T. Limón-Hernández, G. De-la-fuente, G. Garza-Ponce and M. Monroy-Hernández
What Pemex plans for major nitrogen injection, facility extensions and drilling to offset production decreases in this 1-million-bopd field
Solving problems with overboard water handling systems

T. Frankiewicz and J. Clemens
Unocal describes specific steps taken to diagnose and correct offshore water treating problems. Three case studies are presented
Technical advances improve offshore, deepwater operations

D. H. Long and J. B. Long
How a three-stage method was used in Western Canada to cut time and cost of fighting lost circulation to cement casing to surface
Drill fluid stored in semi ballast tanks controls shallow water flow

L. Morales
How limitations for storing/ handling large volumes of special mud for shallow-hole problems were solved for a deepwater well
Eliminating twist-offs as a cause of drillstring failure

A. Baryshnikov, F. Donati, J. Gazanchan and V. Semin
Newly revised technical specs can maintain the serviceability of drillstring components subject to extreme downhole conditions, tension and torsion
How in situ expansion affects casing and tubing properties

R. D. Mack, T. McCoy and L. Ring
Running smaller casing and expanding it downhole with a lubricated cone provides completion advantages and compatible metal property changes
Seismic tomography applied to complex, faulted formation

A. Vesnaver, G. Bohm, G. Madrussani, G. Rossi and H. Granser
Data from the Vienna basin shows that reflection tomography provides good pre-stack depth migration model for defining geologic formations
Ultrasonic measurements monitor casing offset damage
