Rosneft broke another world record Tuesday after drilling the world’s longest well at the Chayvo field off the coast of Russia’s Sakhalin Island.
The O-14 production well was drilled to a record breaking depth of 44,291 feet with a horizontal reach of 39,478 feet.
The well is part of the Sakhalin-1 project that includes the offshore Chayvo, Odoptu and Arkutun-Dagi fields.
Since the start of drilling at Sakhalin-1 the company has broken nine world records including setting two consecutive records for measured depth in 2013.
Russia’s Rosneft said the extended reach drilling was among the fastest ever thanks to ExxonMobil’s proprietary Fast Drill process.
“This well continues successful implementation of our outstanding project. I would like to express my thanks to our partners – ExxonMobil. Usage of their drilling technologies made this achievement possible,”Rosneft head Igor Sechin said.
The Sakhalin-1 project has produced 80 million tons of oil and 16 billion cubic meters of gas since Rosneft turned on the tap at Chayvo in 2005.
Ultimate recoverable reserves at the project are estimated at 236 million tons of oil and 487 billion cubic meters of gas.
Rosneft holds a 20 percent stake, ExxonMobil holds a 30 percent stake, Sakhalin Oil and Gas Development Co. (SODECO) holds a 30 perncent stake and India-based ONGC Videsh holds a 20 percent stake.
Since the beginning of the drilling program in 2003, Sakhalin-1 has set several world records for extended reach drilling. With this new well, the Sakhalin-1 consortium holds drilling records for 9 of the world’s 10 longest wells.
In 2013, two consecutive world records for measured depth were set as part of the Sakhalin-1 project. In April of that year, the Z-43 well reached a measured depth of 12,450 m, and in June the Z-42 well achieved a measured depth of 12,700 m and a horizontal reach of 11,739 m.
In April 2014, the drilling team drilled and completed the Z-40 well; this well set a new record with a measured depth of 13,000 m and a horizontal reach of 12,130 m.
You would hope that the so called environmentalists would be happy at the smaller footprint on other peoples property.
Who measures oil in tons?
What is meant by "horizontal reach"?
Is it the horizontal component of slant drilling? Or, is it the horizontal dimension of the oil deposit? Or, something else?
And yet the enviro whackos are sure the world is running out of oil. We haven’t touched the tip if the reserves yet.
And that's why I have a hard time believing the theory of where oil comes from. Somehow I just don't believe it got there from millions of years of organic decay...given the jungles of Africa and S. America are ripe with thousands upon thousands of years of organic decay and it's only skin deep.
Most of the world outside the US, Canada and England.
To complicate the matter, the volume conversion changes depending on the specific gravity of the oil.

Amoco drilled and sent vibrator trucks (don’t recall their actual name) all over S. Iowa. Wife’s relatives farm near Omaha and remember the shaking that went on.
The big hole was close to Iowa City, where I went to school.
I agree with that. Controversial, I suppose, but I have a very hard time imagining vast amounts of ancient organic matter accumulating in sedimentary rock seven miles beneath the ocean.
To me, it’s about as likely as finding oil on top of Mt Everest. “It started in a swamp ... and then it moved to this new location ...”
Now an abiotic theory of oil actually forming deep in the crust, and being constantly renewed — that seems more sensible. But it’s not my field.
Do you understand the crude oil contains microfossils of the the organisms laid down in the sediment from that time period?
There are three groups which are of particular importance to hydrocarbon exploration. (The uses of microfossils in developing oil fields are analogous to those in exploration and so for brevity I will use the term exploration, which is looking for new resources, without the addition “development” or “exploitation” which refer to the drilling of wells to develop a field found by exploration.) The three microfossil groups most commonly used are: foraminifera, calcareous nannofossils, and palynomorphs. A brief introduction to each of these groups is included {at the link}

Well, you are certainly more of an expert than I am. But I don’t consider it settled science. However, I can’t push it because it’s not my field.
Do you understand that oil production is only from sedimentary basins?
I said so in comment #15. It’s almost always the case. But I believe some oil has been found in granite — but that is explained as a reservoir environment holding oil which has leaked from a sedimentary source of origin. Which could well be true. Or it could be a justification to prop up a theory which may have been weakened by a counter-example.
