Gulltopp is world record well

NORWAY: StatoilHydro has successfully completed the most complicated well in the company's history, and has set a record for the longest producing well in the world drilled from an offshore platform.
At almost 10 kilometres (6.2 miles) long and almost completely horizontal, the Gulltopp well on the Gullfaks field has seen hydrocarbons flowing up through the well at 9,910 metres (32,513 ft).
StatoilHydro Head of Operations West Arne Sigve Nylund said, "This is a day of rejoicing both for Gullfaks and StatoilHydro. We were aware of the risk that Gulltopp drilling from the platform might fail. This makes it extra great that we today have successfully completed the company's most demanding drilling operation."
The experience gained by StatoilHydro is very valuable to the further development of both remote prospects at Gullfaks and on other fields in the company's portfolio.
"The increased range that we now envisage for platform drilling opens up new perspectives for effective exploitation of existing infrastructure, and thus increased producing life," Nylund says.
Gulltopp will, together with other prospects in the area, secure continued Gullfaks operations towards 2030. An extensive plan for how to extend the life of the field, which came on stream back in 1986, has been developed.
The 10 kilometre (6.2 mile) drill pipe was controlled from the drilling rig at the sea surface. It was run 150 metres (492 ft) down to the seabed, and then kilometre after kilometre through various types of rock strata.
The longer the drill pipe is, the more difficult it is to control the forces that are transferred to the drill bit down in the deep, thousands of metres away. This requires great attention and skills by personnel in charge of drilling.
"The Gulltopp well has been a great technological challenge, and was possible thanks to high professional skills among our own drilling and well personnel, in addition to crucial contribution by the involved suppliers," said Geir Slora, head of drilling and wells in StatoilHydro.

New Horizontal Drilling Record: 35,770 Feet!
Imagine logging, interpreting, setting casing, perforating, and fracing a horizontal section of a well 35,770 long? Amazing.

Transocean rig breaks world drilling record
Filed from Houston 5/21/2008 1:51:37 PM GMT (source)
QATAR: Offshore drilling contractor Transocean is claiming a new world record for the longest extended-reach well ever drilled. Transocean jackup GSF Rig 127 set the record, drilling Well BD-04A in the Al-Shaheen field offshore Qatar to a depth of 40,320 feet (12,289 m) with a 35,770-foot (10,902-m) horizontal section.
The well is the first offshore well to exceed 40,000 feet (12,191 m) and breaks the previous extended-reach record holder, ExxonMobil's Sakhalin-1 well in Russia's Chayo field, by 2,000 feet (6,096 m).
During the 36 incident-free days of drilling, the crew members on GSF Rig 127 overcame high drilling torque through the horizontal section, and used deck-management planning and a supply boat to hold additional drill pipe, allowing the rig to stay within its variable deck load rating.
GSF Rig 127 is a Friede & Goldman L-780 Mod II design jackup, with 250-foot (76.2-m) water depth capability and operates with two Emsco FB 1600 Mud pumps. Other equipment includes a 2000-horsepower National 1320 UE Drawworks, and a Varco TDS-4S Top Drive.
Transocean Egypt and Middle East Division Manager Gary Bauer lauded the crew of the rig. "It goes without saying that your accomplishment truly epitomizes and embraces Transocean's vision statement where Rig 127 has a group of highly motivated people dedicated to achieving operational excellence in an incident-free environment and being recognized for delivering superior performance. Well done to the entire Rig 127 Team and continued success in delivering safe, superior performance."

More Horizontal Drilling Success
If there is a bright spot, (sorry seismic interpreters, no pun intended) in today's domestic oil and gas industry, it seems to lie in the area of horizontal drilling, completion and production from so-called unconventional reservoirs. The following notes are from two recent examples reported in the February 16 issue of the Oil and Gas Journal, page 36.
Note in particular the GeoResources, Inc. well in the Austin Chalk of south Texas' Giddings Field that produced 1BCF in its first 60 days of production. At $4/MCF, that equals $4 Million return in 60 days, which probably paid the cost of drilling and completing the well. Not bad, I'd say.
Petrohawk Energy Corp. of Houston is also doing very well with their wells in the Haynesville Shale Play in NW Louisiana and the Fayetteville Shale Play in Arkansas, both involving horizontal drilling. The company claims to have replaced "419 % of its production in 2008". Now that is the kind of economic stimulation we could use more of!
