In 2012, the number of unconventional tight gas/shale and high-pressure/high-temperature (HP/HT) papers continued to grow. This year, we had some very interesting developments in these and other areas of well construction.

This case history presents the highly challenging extended-reach deepwater well, Ursa A-10, drilled in the Ursa (Latin for bear) prospect in the US Gulf of Mexico (GOM).

To maintain zonal isolation throughout the life of a high-pressure/high-temperature (HP/HT) well, the cement sheath must perform reliably at temperatures that can exceed 315°C.

The deepwater Gulf of Mexico is a technically and economically challenging production environment. High rates and ultimate recoveries are required per well to offset high development costs.

The Eagle Ford shale in Zavala County, Texas, is similar to many high-carbonate-content oil-shale formations.

The Granite Wash formation presents several challenges in drilling the build section from a vertical open hole to form a lateral.

The Liwan gas reservoir was discovered in the South China Sea Block 29/26 in September 2006.

The Mensa field is a deepwater Gulf of Mexico (GOM) geopressured-gas field, producing from Upper Miocene sand with faulted four-way closure.

Question and Answer interview with Phil Andrews

Setting optimal surface separation pressures are crucial for maximizing the surface liquid production from the wellstream feed. Where separator tests are not available, empirical calculations are often used, but with limitations. A method suitable across many conditions is proposed.
