In a prior interview about coalbed methane (CBM), Sprott Asset Management CBM analyst Eric Nuttall advised us he would stay, “quite excited about the prospects for companies with coal bed methane assets so long as natural gas prices remain above $6 per Mcf (thousand cubic feet). The economics would be very skinny under $6.” That’s as a result of CBM exploration and building can get dear. What if there used to be a drilling company incessantly bringing gasoline out of the bottom for only $1.50/mcf? There is and they have confirmed it with greater than 250 wells in Australia. They’ve moved into India, the place they drilled some other 30 to 50 wells and some other 70 wells to come back. Mitchell has taken acreage in southern Kansas, the place the corporate simply completed its first CBM smartly. And the corporate shaped a three way partnership with Pacific Asia China Energy (TSX: PCE) to convey its Dymaxion® generation to China later this yr.
You do not get to be Australia’s biggest privately owned drilling corporate with out timing your markets proper. The Mitchell circle of relatives’s nice timing skill started in 1969, when corporate founder Peter Mitchell purchased his first drilling rig at a repossession sale for $11,500. Parts of Queensland, Australia had been within the grips of a drought. Mitchell put his rig to just right use as he started drilling water wells for farmers within the surrounding rural counties. Just because the drought had ended, Mitchell stuck the growth in coal. His rising corporate started drilling within the oil shale and coal fields round Moranbah, then a far off a part of Queensland. They then stuck the drilling growth in mineral assets in the course of the Eighties. By then, the corporate used to be drilling oil, gasoline, uranium and coal reserves right through Australia. In the Nineties, Mitchell Drilling were given the primary whiff of Coalbed Methane (CBM) exploration coming into Australia. That is when the key U.S. oil corporations, reminiscent of Amoco, Conoco and others, got here to the rustic in search of new CBM fields.
But, the key U.S. oil corporations deserted CBM in Australia as a result of they quickly came upon Australia’s shallow coal fields had been too pricey for his or her giant oil rigs. “The economics just didn’t work,” Nathan Mitchell advised InventoryInterview. “They needed high gas flow, but the fracing technique just didn’t give them what they needed.” Still they continued and requested Mitchell Drilling to run his smaller water smartly rigs. “That was the start of it,” Mitchell recalled. “We made CBM work with the water well rigs from an economics point of view, but they still weren’t making enough gas.” Still, the economics of the smaller rig made it paintings to some extent.
Enter the politicians. “The Queensland government made a law that said five percent of all coal-fired power stations had to be run by gas,” defined Mitchell. “That spawned the industry and CBM really took off.” Mitchell persevered with the vertical rigs, nevertheless it used to be the economics of the smaller rig that made CBM paintings.
GETTING BLOOD OUT OF A STONE
It used to be right through the CBM growth when Mitchell advanced the simpler mousetrap. Coal miners did not see the gasoline useful resource underneath their toes. “They just saw them as coal fields,” mentioned Mitchell who knew there used to be “nuisance gas” there. “There was never even a thought there was enough gas there to make it viable.” With herbal gasoline promoting for $2/mcf in Australia, the economics did not make sense. Australian coal seams are discovered at shallower ranges the place better pressures must be created to free up gasoline from the prolonged horizontal seams. The Australian one-two punch of shallow coal seams and occasional gasoline costs drove Mitchell to transform leading edge.
“We’d seen in the coal business the underground in-seam drilling of horizontal holes and degasification,” Mitchell defined. “But, there was usually a lot of water involved and no way to get the water out.” Because of the corporate’s a long time of enjoy in drilling water wells, Mitchell mixed the vertical smartly with the horizontal smartly. Mitchell described the method, “The vertical well became the conduit for the coal mine, the gas and the water, and gave us a huge surface area. Suddenly, in areas where there wasn’t a resource, we could produce something like a million or up to 2 million a day from these Dymaxion® wells.”
The generation used to be put to the check in central Queensland, Australia. An Australian newspaper reported in June 2004, “In an industry where tradition plays a strong role, innovative drillers Mitchell Drilling have chalked up the 100th example of their revolutionary Dymaxion surface to in-seam (SIS) methane gas drainage hole for gas producer CH4 Limited at their Moranbah gas project.” CH4’s website online spoke extremely of this gasoline challenge, “The Moranbah Gas Project will utilise innovative drilling and gas extraction techniques, allowing increased potential gas yields while leaving the coal resource undamaged.”
How does this have an effect on the business? “We see this as revolutionary,” Mitchell cheerily remarked. “It has changed the face of CBM. It works in areas where people didn’t think it would work.” For instance, the Dymaxion® drilling works in prime permeability with low gasoline. “We can get such high gas from low gas content reservoirs, where people didn’t previously think there were reservoirs.”
It has labored in Australia, the place each penny counts. “Our price may cost around $1.25 or $1.10 (US$) per mcf so they are still making reasonable profits at around 50 percent.” How will it play out of doors of Australia? Mitchell shot again, “If you can imagine costs at $1.25 and you’re selling it for $6/mcf, that’s some pretty good bloody profits.” Drilling at affordable income for $2 gasoline, Mitchell mentioned, “We are keen to take this technology around the world. Even if we were to double our costs, our clients would still be extremely happy.”
USING BOTH VERTICAL AND HORIZONTAL WELLS
When discussing the Dymaxion® generation with an oil and gasoline guy, his at a loss for words reaction used to be, “Did I hear you right? You are using both a vertical and horizontal wells to get the gas?” There are the skeptics. “Contractors from the larger oil and gas companies came over to have a look,” Mitchell mentioned. “Some people thought we were sliding by or sort of skimming costs.” He defined the process, “We have to intercept (the vertical) because we actually line up every one of our lateral wells with a slotted liner, a perforated liner. It is stacked into the vertical well, by the arrangement we’ve developed, so we know we’ve intercepted it.”
Mitchell mentioned the bottom line is the power to flush and know that the reveals are popping out. “We can have a number of wells lined, going from one point to another,” he defined, “and we’ve got continuity of connection and flow between one well which is 1000 to 2000 meters away and the vertical well. We can flush between both.” He gave an instance, “We can have three horizontals going into one vertical and two of the horizontals can be closed. Number one can be opened and flushed; then number two can be open, flushed and closed. So you have this over the 10 to 20 year life of the well.”
How does the SIS hollow de-gas a better space than an ordinary horizontal? “When we put two wells into a chevron pattern, you start to get absorption between the V at the start of the well,” Mitchell mentioned, describing the Dymaxion procedure. “Once you get the wells done, in a V with each other, you start to get better flows, a bit more gas and greater increasing gas in a slow decline.”
Mitchell’s website online does admit the previous applied sciences could also be appropriate for deeper drilling, “In the case of very deep deposits, up to 3000 meters underground, a vertical well may be adequate to create sufficient water table pressure to liberate and bring to the surface large quantities of methane gas.” Because of the better floor space draining the underground gasoline within the coal seams, the similar website online is fast to show, “SIS drilling also provides valuable exploration data on seam rolls and faults, allowing greater certainty in mine planning and development.”
The SIS procedure starts through the usage of changed, multipurpose mineral drill rigs with specifically designed backside hollow assemblies. In the SIS method, a hollow is drilled at 60 to 90 levels from the skin. It is then instructed via a medium radius bend to horizontally input the objective coal seam. The 96 millimeter hollow is instructed within the seam towards a in the past drilled vertical manufacturing smartly. A homing software is reduced down the vertical smartly to the objective seam, which is helping the horizontal hollow intersect the manufacturing smartly. The vertical smartly dewaters the seam. Once the hydrostatic head has sufficiently been reduced, gasoline flows to the skin.
MITCHELL’S WORLDWIDE EXPANSION
Developing the Dymaxion® generation within the past due Nineties, the primary check happened in Australia within the yr 2000. Now, happening just about seven years later, the corporate has drilled greater than 250 wells in Australia, some other 30 to 50 wells in India with some other 70 extra to drill, and has moved directly to each Kansas and China. Mitchell mentioned Kansas, “We finished our first well, but we don’t really want to be a contractor in the United States. We don’t see a lot of benefit to handing over our technology, but we would be interested in doing some sort of equity deal or partnership with clients.” He believes that during the correct spaces, what Mitchell has were given is “exceptionally good.”
So the place did Mitchell first make an fairness deal? “The two big powerhouses of the world for the future are going to be China and India,” he famous. “Both of them will have energy problems in the future. Mitchell’s first equity deal came about with Pacific Asia China Energy. “We simply astounded them with what used to be taking place in Australia,” Mitchell laughed, “to look this small compact rig drilling 2000 meter holes of a smartly and making it paintings at $2 gasoline.” He explained that although rigs were cheaper in China, the logistics, the costs of roads and access for trucks and pumps, gear and equipment, costs start to go up. “It like a U.S. plane service,” Mitchell compared with a drilling operation, “you have got 40 planes on deck nevertheless it takes 70 other people to run it.” Even in China, prices can pass up when operating those logistics. The maintain Pacific Asia China Energy comes to diminished drilling prices and a 50/50 association for source of revenue produced via using the Dymaxion® generation in China. The three way partnership corporate has unique use to this generation on the planet’s biggest coal generating nation, China.
How does Mitchell see trade rising in China? “Exponentially,” he temporarily answered. “In China, there is a push to degasify their mines. There are some several thousand large mines, many with over one hundred million tons in reserves, and a lot of mines are being shut down because of degasification problems.” In an previous interview with the Tunaye Sai, president of Pacific Asia China Energy, he reported that each unmarried coal corporate at a up to date symposium approached each Mitchell and himself in regards to the Dymaxion generation for China. Was that true? “Very much so,” Mitchell showed. “Mine safety is now at the forefront of China and international observation. They’re looking forward to international help and technology to come to China and fix these problems. They’re looking at it from they want to sell coal, but they also want to sell gas. It worked well in Queensland and will apply to in China. That’s why we see such a growth for Mitchell.”
