Oil Fields Are Refilling...Naturally - Sometimes Rapidly By Robert Cooke – Newsday.com April 10, 2005 Deep underwater, and deeper underground, scientists see surprising hints that gas and oil deposits can be replenished, filling up again, sometimes rapidly. Although it sounds too good to be true, increasing evidence from the Gulf of Mexico suggests that some old oil fields are being refilled by petroleum surging up from deep below, scientists report. That may mean that current estimates of oil and gas abundance are far too low. Recent measurements in a major oil field show "that the fluids were changing over time; that very light oil and gas were being injected from below, even as the producing [oil pumping] was going on," said chemical oceanographer Mahlon "Chuck" Kennicutt. "They are refilling as we speak. But whether this is a worldwide phenomenon, we don't know." Also not known, Kennicutt said, is whether the injection of new oil from deeper strata is of any economic significance, whether there will be enough to be exploitable. The discovery was unexpected, and it is still "somewhat controversial" within the oil industry. Kennicutt, a faculty member at Texas A&M University, said it is now clear that gas and oil are coming into the known reservoirs very rapidly in terms of geologic time. The inflow of new gas, and some oil, has been detectable in as little as three to 10 years. In the past, it was not suspected that oil fields can refill because it was assumed the oil formed in place, or nearby, rather than far below. According to marine geologist Harry Roberts, at Louisiana State University, "petroleum geologists don't accept it as a general phenomenon because it doesn't happen in most reservoirs. But in this case, it does seem to be happening. You have a very leaky fault system that does allow it to migrate in. It's directly connected to an oil and gas generating system at great depth." What the scientists suspect is that very old petroleum -- formed tens of millions of years ago -- has continued migrating up into reservoirs that oil companies have been exploiting for years. But no one had expected that depleted oil fields might refill themselves. Now, if it is found that gas and oil are coming up in significant amounts, and if the same is occurring in oil fields around the globe, then a lot more fuel than anyone expected could become available eventually. It hints that the world may not, in fact, be running out of petroleum. "No one has been more astonished by the potential implications of our work than myself," said analytic chemist Jean Whelan, at the Woods Hole Oceanographic Institution, in Massachusetts. "There already appears to be a large body of evidence consistent with ... oil and gas generation and migration on very short time scales in many areas globally," she wrote in the journal Sea Technology. "Almost equally surprising," she added, is that "there seem to be no compelling arguments refuting the existence of these rapid, dynamic migration processes." The first sketchy evidence of this emerged in 1984, when Kennicutt and colleagues from Texas A&M University were in the Gulf of Mexico trying to understand a phenomenon called "seeps," areas on the seafloor where sometimes large amounts of oil and gas escape through natural fissures. "Our first discovery was with trawls. We knew it was an area of massive seepage, and we expected that the oil seeps would poison everything around" the site. But they found just the opposite. "On the first trawl, we brought up over two tons of stuff. We had a tough time getting the nets back on board because they were so full" of very odd-looking sea.floor creatures, Kennicutt said. "They were long strawlike things that turned out to be tube worms. "The clams were the first thing I noticed," he added. "They were pretty big, like the size of your hand, and it was obvious they had red blood inside, which is unusual. And these long tubes -- 3, 4 and 5 feet long -- we didn't know what they were, but they started bleeding red fluid, too. We didn't know what to make of it." The biologists they consulted did know what to make of it. "The experts immediately recognized them as chemo-synthetic communities," creatures that get their energy from hydrocarbons -- oil and gas -- rather than from ordinary foods. So these animals are very much like, but still different from, recently discovered creatures living near very hot seafloor vent sites in the Pacific, Atlantic and other oceans. The difference, Kennicutt said, is that the animals living around cold seeps live on methane and oil, while the creatures growing near hot water vents exploit sulfur compounds in the hot water. The discovery of abundant life where scientists expected a deserted seafloor also suggested that the seeps are a long-duration phenomenon. Indeed, the clams are thought to be about 100 years old, and the tube worms may live as long as 600 years, or more, Kennicutt said. The surprises kept pouring in as the researchers explored further and in more detail using research submarines. In some areas, the methane-metabolizing organisms even build up structures that resemble coral reefs. It has long been known by geologists and oil industry workers that seeps exist. In Southern California, for example, there are seeps near Santa Barbara, at a geologic feature called Coal Oil Point. And, Roberts said, it's clear that "the Gulf of Mexico leaks like a sieve. You can't take a submarine dive without running into an oil or gas seep. And on a calm day, you can't take a boat ride without seeing gigantic oil slicks" on the sea surface. Roberts added that natural seepage in places like the Gulf of Mexico "far exceeds anything that gets spilled" by oil tankers and other sources. "The results of this have been a big surprise for me," said Whelan. "I never would have expected that the gas is moving up so quickly and what a huge effect it has on the whole system." Although the oil industry hasn't shown great enthusiasm for the idea -- arguing that the upward migration is too slow and too uncommon to do much good -- the search for new oil and gas supplies already has been affected, Whelan and Kennicutt said. Now, companies scan the sea surface for signs of oil slicks that might point to new deposits. "People are using airplane surveys for the slicks and are doing water column fluorescence measurements looking for the oil," Whelan said. "They're looking for the sources of the seeps and trying to hook that into the seismic evidence" normally used in searching for buried oil. Similar research on known oil basins in the North Sea is also under way, and "that oil is very interesting. There are absolutely marvelous pictures of coral reefs which formed from seepage [of gas] from North Sea reservoirs," Whelan said. Analysis of the ancient oil that seems to be coming up from deep below in the Gulf of Mexico suggests that the flow of new oil "is coming from deeper, hotter formations" and is not simply a lateral inflow from the old deposits that surround existing oil fields, she said. The chemical composition of the migrating oil also indicates it is being driven upward and is being altered by highly pressurized gases squeezing up from below. This upwelling phenomenon, Whelan noted, fits into a classic analysis of the world's oil and gas done years ago by geochemist-geologist John Hunt. He suggested that less than 1 percent of the oil that is generated at depth ever makes it into exploitable reservoirs. About 40 percent of the oil and gas remains hidden, spread out in the tiny pores and fissures of deep sedimentary rock formations. And "the remaining 60 percent," Whelan said, "leaks upward and out of the sediment" via the numerous seeps that occur globally. Also, the idea that dynamic migration of oil and gas is occurring implies that new supplies "are not only charging some reservoirs at the present time, but that a huge fraction of total oil and gas must be episodically or continuously bypassing reservoirs completely and seeping from surface sediments on a relatively large scale," Whelan explained. So far, measurements involving biological and geological analysis, plus satellite images, "show widespread and pervasive leakage over the entire northern slope of the Gulf of Mexico," she added. "For example, Ian MacDonald at Texas A&M has published some remarkable satellite photographs of oil slicks which go for miles in the Gulf of Mexico in areas where no oil production is occurring." Before this research in oil basins began, she added, "changes in reservoired oils were not suspected, so no reliable data exists on how widespread the phenomenon might be in the Gulf Coast or elsewhere." The researchers, especially the Texas team, have been working on this subject for almost 15 years in collaboration with oil industry experts and various university scientists. Their first focus was on the zone called South Eugene Island block 330, which is 150 miles south of New Orleans. It is known as one of the most productive oil and gas fields in the world. The block lies in water more than 300 feet deep. As a test, the researchers attempted to drill down into a known fault zone that was thought to be a natural conduit for new petroleum. The drilling was paid for by the U.S. Department of Energy. Whelan recalled that as the drill dug deeper and deeper, the project seemed to be succeeding, but then it abruptly ended in failure. "We were able to produce only a small amount of oil before the fault closed, like a giant straw," probably because reducing the pressure there allowed the fissure to collapse. In addition to the drilling effort and the inspection of seeps, Whelan and her colleagues reported that three-dimensional seismic profiles of the underground reservoirs commonly show giant gas plumes coming from depth and disrupting sediments all the way to the surface. This also shows that in an area west of the South Eugene Island area, a giant gas plume originates from beneath salt about 15,000 feet down and then disrupts the sediment layers all the way to the surface. The surface expression of this plume is very large -- about 1,500 feet in diameter. One surprise, Whelan said, was that the gas plume seems to exist outside of faults, the ground fractures, which at present are the main targets of oil exploration. It is suspected that the process of upward migration of petroleum is driven by natural gas that is being continually produced both by deeply buried bacteria and from oil being broken down in the deeper, hotter layers of sediment. The pressures and heat at great depth are thought to be increasing because the ground is sinking -- subsiding -- as a result of new sediments piling up on top. The site is part of the huge delta formed over thousands of years by the southward flow of the massive Mississippi River. Like other major deltas, the Mississippi's outflow structure is continually being built from sands, muds and silts washed off the continent. Analysis of the oil being driven into the reservoirs suggests they were created during the so-called Jurassic and Early Cretaceous periods (100 million to 150 million years ago), even before the existing basin itself was formed. This means the source rock is buried and remains invisible to seismic imaging beneath layers of salt. In studying so-called biomarkers in the oil, Whelan said, it was concluded that the oil is closely related to other very old oils, implying that it "was probably generated very early and then remained trapped at depth until recently." And, she added, other analyses "show that this oil must have remained trapped at depths and temperatures much greater than those of the present-day producing reservoirs." At great depth, where the heat and pressure are high enough, she explained, methane is produced by oil being "cracked," and production of gas "is able to cause sufficient pressure to periodically open the fracture system and allow upward fluid flow of methane, with entrapment of oil in its path." forum.atimes.com/topic.asp?TOPIC_ID=1106 Also see Joe Vialls: Russian Proves “Peak Oil” is Misleading Zionist Scam www.vialls.com/wecontrolamerica/peakoil.html Poster Comment: Note this article is from FIVE YEARS AGO.

Taken from the article "The Wildlands Project: Land Conservation Strategy" in the 1992 special issue of Wild Earth, Noss provides the whopping dimensions of this effort. Core reserves are wilderness areas that supposedly allow biodiversity to flourish. "It is estimated," claims Noss, "that large carnivores and ungulates require reserves on the scale of 2.5 to 25 million acres. . .. For a minimum viable population of 1000 [large mammals], the figures would be 242 million acres for grizzly bears, 200 million acres for wolverines, and 100 million acres for wolves.

you only need half a brain to figure out the gamez. the guys who stand to benefit tell you that the commodity they sell is scarce and drying up, trying to underestimate supply to increase price. 'peak oil'.....um, so these guys are in the habit of being truthful to the markets? not quite. further, one would only need to run a 'peak oil' PR snow job IF the opposite were true, that the supply is huge and prices are inflated. duh.
I read Joe Vialls before his mouth was sealed forever. Besides the peak oil myth, I believe we are on the cusp of cheap or even free, clean energy....if they would just stop killing the people trying to bring it forward.

They like to hate the oil and petrodollar economy. It is politically useful to the Bildyburger types. They like the control, the tight regulation, keeping out small companies. So even if something new comes along, don't expect it to succeed. At least, if it isn't based on American corn crops.
