NATURAL GAS IS MONEY IN THE GROUND TO A GAS COMPANY. IT'S JUST A MATTER OF GETTING TO IT...AND THANKS TO EVER-IMPROVING DRILLING TECHNOLOGY, THEY'RE GETTING TO IT FASTER AND MORE EFFICIENTLY THAN EVER. KSLA NEWS 12'S CAROLYN ROY TAKES US ON A TOUR OF A DRILLING RIG IN ACTION. THE NATURAL GAS TRAPPED DEEP BENEATH THE ARKLATEX IS ABOUT TO TRANSFORM THE LANDSCAPE UP HERE ON THE SURFACE, LITERALLY...THANKS TO RIGS LIKE THESE. "Some of it's supports, a lot of it's lifting". THESE TOWERS OF STEEL, CABLE AND MACHINERY ARE CRITICAL TO THE PROCESS OF PULLING THE PRECIOUS MINERAL FROM AN ANCIENT SHALE FORMATION NEARLY A MILE AND A HALF UNDERGROUND. BORN 300-MILLION YEARS AGO WHEN MOST OF TEXAS AND LOUISIANA WERE COVERED BY A SHALLOW OCEAN. IRELAND the ocean eventually dried up and there were continent shifts over geologic time that eventually covered up what was the bottom of the ocean and is now the shale. SMALL ORGANISMS EMBEDDED IN THE MUD WERE TRAPPED...AND THE MUD HARDENED INTO A TIGHTLY-PACKED LAYER OF ROCK. UNDER HEAT AND PRESSURE.THAT ORGANIC MATERIAL BROKE DOWN INTO METHANE.WHAT WE KNOW AS NATURAL GAS. GEOLOGISTS AND GAS COMPANIES HAVE LONG KNOWN THAT GAS IS TRAPPED IN THE SHALE -- IT'S ONLY RECENTLY THAT TECHNOLOGICAL ADVANCES HAVE ALLOWED THEM TO GET TO IT. "the technology of everything involved is advanced, making , you know, they could have done this 20 yrs ago, but what we're doing now on an avg of 21 days may have taken them 60 or 70 days". AND HIGHER GAS PRICES HAVE MADE IT ALL WORTHWHILE. "The Barnett shale, 15 years ago, was not a productive zone they couldn't have they couldn't have - they could drill the wells, but they could not economically complete em and get them to produce, and with the evolution of the completion technologies and the change in how they were fracing the wells, we were able to make them more productive and with the advancement of drilling technology we can drill them much quicker, 3:35:44 and although this is high dollar equipment, the faster we drill em, we can drill em more economically now". ADVANCES IN HORIZONTAL DRILLING...SENDS A THICK STEEL PIPE ALONG =INSIDE= THE SHALE INSTEAD OF SIMPLY STRAIGHT DOWN =THROUGH= IT. "doesn't look like it would bend, but it does, when you get out there several thousand feet - it bends". THAT PIPE IS LATER ENCASED IN CONCRETE TO PROTECT DRINKING WATER...AND PERFORATED WITH NUMEROUS SMALL CHARGES, SO THAT IT CAN COLLECT MORE TRAPPED GAS THROUGH A MUCH LARGER SURFACE AREA. DEPENDING ON THE SITE, AS MANY AS 18 WELLS CAN BE DRILLED EACH PAD LOCATION IN THE BARNETT SHALE...USUALLY A TWO-TO-FOUR ACRE AREA....AND EACH HORIZONTAL WELL CAN DRAW GAS FROM UNDERNEATH PROPERTY AS FAR AS A MILE AWAY. BUT THE RIG IS ONLY TEMPORARY. AT THIS COMPLETED SITE IN BURLESON, TEXAS, THERE ARE FOUR WELLHEADS LEFT BEHIND, PRODUCING GAS. MORE WELLS, MORE GAS...MORE MONEY...AND MORE WORK FOR THESE GUYS. "They're out here 24 hrs a day." CHESAPEAKE SAYS EACH RIG BRINGS 187 PERMANENT JOBS......PAYING 22 DOLLARS AN HOUR AND UP. "you can't just bring anybody in and put em up there and say hey we're gonna tread pipe. There's an art to throwin tongs on, it's an art pulling sleds, there's techniques, slips weigh 300lbs you know, 5" slips weigh 300 lbs these probably weigh 200 - and it takes 3 men to do em". NO DOUBT IT'S DIFFICULT. "that's the clean mud goin in, goin down the pipe, comes out the drill bit, carries the cuttings up". AND DIRTY WORK. "there's mixers in these tanks, these tanks here contain all the mud and this system probably has about 12 hundred barrels of mud, a thousand barrels of mud 3:18:08 so there's a total of about a thousand barrels of mud in here that is continuously circulated through". UP ABOVE, ON THE RIG PLATFORM, A PRECISE ROUTINE PLAYS OUT OVER AND OVER. "we track it every thirty feet, so we know every thirty feet where we're at in the hole". SENDING PIPES EVER DEEPER INTO THE EARTH. "we're at 45 hundred feet (will have to cover very beginning of this sot bc of movement) going to 10,700". ALL TO HARVEST THE BOUNTY FROM BELOW
