Geothermal – Geothermal Pilot Project in Finland Reaches Stimulation Stage | Borehole Hammer

Azad Foundation’s Women on Wheels programme helps them to take up driving as a profession. What better way to …

None of this is rocket science, which helps explain a paradox of most conversations with scientists, ecologists and charity-workers who have devoted their lives to solving the world’s water problems. Most are full of horror stories about how woefully the world is misusing and wasting its water. Yet most will profess cautious optimism about the long-term future.

Pieter explains that the Northern Cape area presents some of the most challenging conditions in the world. “We drill into some of the hardest rock in the world, with compressive strengths above 500MPa under extreme surface and weather conditions; these drilling machines take a huge hammering. While most machines start to fall apart after only a short time of drilling, the Epiroc drill rigs give us up to 80% availability over many years of operation. Only machines of this exceptional quality will last for 30 000 hours plus.

"Before I had the dream about the Village Drill, I had never seen a well drilled before," Renouard said. "It was certainly something worth fighting for."

Later, Marty and Doug Crowell meet with Joe in order to analyze the samples with more sophisticated equipment. Using a microscope capable of enlarging the samples to 400 times their actual size, a crystalline substance is discovered, which could be pigment, perhaps a Medieval or Renaissance ink.

Dr Padley added: “I can assure everyone that the water will continue to meet the very strict safety standards set out by the Drinking Water Inspectorate.

Balance quality control and production rather than speed when motivating drillers. Otherwise, operators may take shortcuts to gain footage, but compromise safety and overall cost.

- The resettlement of Daapleu is complete and the official ceremony of handing over the houses took place on December 10, 2018.

It provides measures of the average density of the formation (i.e. rock & fluids combined). In most cases, the density log is interpreted to give information about the porosity, fluid type and fluid saturation.

2019 is expected to be another strong year as we look forward to the first gold pour at the Ity CIL plant in the coming weeks, where construction continues to progress ahead of schedule and on budget. Over the past two years, we have transformed our portfolio, investing nearly $1 billion into the business. Once Ity CIL commences production, we expect to enter a period of sustained strong free cash flow generation with a continued focus on return on capital employed.

Approximately $8 million of non-sustaining expenditure is planned for 2019, mainly covering work to raise the TSF.

Once drilling is completed, techniques such as acidising or targeted air lifting (surging) may be used to enhance the yield and efficiency of the borehole. This part of the construction phase is referred to as borehole ‘development’.
