“Mobility, flexibility, reliability, efficiency and precision drilling capacity define Epiroc’s ROC family of drilling machines making them the most suitable and up for the task,” states Pieter Malan, General Manager of Booysen Bore Drilling Company, Sishen.

About three and a half minutes into “The Last Good Time,” Oxbow vocalist Eugene S. Robinson seems to screech “What the fuck?!” That’s a natural reaction to some of the band’s material — they built their reputation on being one of the most peculiar and avant-garde bands in noise rock, incorporating elements of jazz, blues, and contemporary classical composition among their terrifying dirges. But they’re also a highly entertaining band at that — their live shows involve incense-lighting rituals and amateur MMA fighter Robinson’s gradual removal of clothing. Their Steve Albini-recorded album Serenade In Red is a conceptual punk-blues noir album that even features a spoken-word guest appearance from Marianne Faithfull. “The Last Good Time,” however, is the band at their most giddily manic, a wild, blazing, slide-driven ride of a track that sounds like it’s going to come off the rails at any moment.

After his dream about the drill, and a series of fortuitous connections, BYU students Devin LeBaron, Eric Jammohamed, Jimmy Stacey, Ken Langely, Nathan Toone and Sabin Gautam worked on the design for eight months as a BYU Capstone project.

Borehole Geophysics is the deployment of geophysical sensing tools into a drilled hole. The sensing tool which is attached to a cable, provides measurement of nearby rock properties in the drilled hole, and sends the information via the cable to a control system unit on the surface where the data is collected and kept for further processing. In petroleum exploration, this method provides a “ground-truth” follow-up to larger geophysical surveys. Instruments interact with rocks in close vicinity, and can provide detailed information on properties such as rock type, permeability, density and velocity.

The scanner then picks up an angular object, one that could be an anchor. If it is indeed an anchor, and from prior to 1795 when the Money Pit was discovered, it could help solve the Oak Island mystery. In the end the team conclude that they definitely saw some anomalies, and are eager to see what transpires once the data is processed. If the data yields promising information, the next step is to put a diver in the water.

Dans ce post, je parlais des **débuts **des tubes cathodiques qui marquaient: c’est pour ne pas marquer les écrans que la fameuse pendule de la RTF http://i.ytimg.com/vi/vUOeYRKFkkw/default.jpg n’était pas fixe sur l’image mais se “baladait” lentement horizontalement et verticalement.

The table below presents the cash flow for the 12 months ended December 31st, based on the All-In Margin approach with accompanying notes below.

These forces are the key variables, and optimizing them can be helped by watching for such things as the size of cuttings coming out of the hole. The chips should be as large as possible, thumbnail-sized ideally. The goal is to minimize the amount of mechanical kinetic energy and heat bouncing back to the drill, while transferring as much energy as possible into the rock to spall and break it. “The challenge has never been about generating enough power. Rather, it is about improving the durability, longevity, and efficient energy transfer of the drill string and cutting tools,” says Hissem. He believes metallurgical advances and new drill technologies have together produced “a modern physics miracle.” Effective operators can tap into this miracle by tuning and balancing the forces being applied.

Watching only gauges can be self-defeating, because, by the time they register an anomaly, something significant already has happened in the ground. Hissem talks of the old days when drill operators were exposed to the heat and cold and dust and noise. “Then we got cabs and old-timers didn’t like it, even though they were more comfortable, because it cut them off from sensory information.” So-called “smart drills” are being developed with onboard intelligence and systems that will separate operators even more from the “feel” of operation. Until such machines dominate drill sites, operators should keep sensing the pulse of their machines. They should actively monitor such things as the flushing action, any pitch changes in the drill string, subtle movements that indicate a change in rock pressure, the size of cuttings, and groundwater. Hissem believes a master driller can fully develop this “sixth sense” in a couple of years.

“I hope politicians realise the fundamental value of food production and include it as part of future policy making. It’s good to have support for the environment but let’s make sure farming is supported too.”

Caernarfon milk producer Aled Jones is NFU Cymru’s deputy president but for now he has his own battles to fight. “The one thing you can’t lobby for as a union is more rainfall,” he sighed.

In 1988 Dan and his son Dave ran a similar dye test at borehole 10X and they saw red dye emerge at Smith’s Cove and along the north and south shores. Unfortunately, Dan lacked the financial resources to follow up this exciting find.
