Huinga - NZ$2 billion well, page-40

I got this information from the exxon website.
I hope this helps when reading todays announcement



Getting more from oil and gas reservoirs around the world

Bass Strait, Australia -increased oil recovery to more than 70 percent in several ExxonMobil-operated fields by applying advanced reservoir modeling techniques, reworking existing wells, drilling new wells, and upgrading surface processing equipment.

Jay Field, Florida - recovering more than 60 percent of the oil from a geologically complex carbonate reservoir with the aid of advanced reservoir modeling techniques and by injecting nitrogen gas.

Groningen Field, Netherlands - embarked on a program to keep facilities up-to-date with respect to safety, environmental requirements, technology and operating efficiency. We expect to recover 97 percent of the gas in this very large and mature field.

Ubit Field, Nigeria - increased the amount of recoverable oil by 500 million barrels through the application of 3-D seismic, advanced reservoir modeling techniques, horizontal wells, and by upgrading surface processing equipment.

Cold Lake, Canada - increased the recovery of heavy (tar-like) oil from 10 percent to more than 25 percent by injecting steam into the formation to heat the oil and make it flow toward the producing wells.

Arun Field, Indonesia - recovering about 94 percent of the gas and 67 percent of the condensate from a mature, lean gas condensate reservoir using compositional reservoir modeling to balance gas injection and maximize condensate recovery.

Prudhoe Bay, Alaska - increased the amount of recoverable oil by 4 billion barrels through the development of advanced geologic models, injecting gas to improve oil recovery, upgrading surface processing equipment, and by using horizontal wells.

Means Field, Texas - increased reserves by 66 million barrels in a mature field by drilling new wells and by injecting water and carbon dioxide to improve oil recovery.

Brent Field, North Sea - increased the amount of recoverable oil and gas by 400 million oil-equivalent barrels through the early reduction of reservoir pressure to liberate gas from residual and bypassed oil. The use of advanced reservoir modeling, reworking existing wells, drilling new wells and and upgrading surface equipment have contributed to the increase in reserves.

Topacio Field, Equatorial Guinea - installing electrically driven multiphase subsea pumps to increase production from four wells by 6,000 barrels a day (2000).
