The production of deep electrical energy begins to be drilled in the geothermal energy project



Estevan – After a decade of developing a geothermal electrical sector concept, Saskatchewan's Deep Earth Energy Production (DEEP) Corp. piles the last hole in the south of Torquay, seen from the American border. Successful projects will install the first geothermal power in Canada.

On November 8, the director directed by Kirsten Marcia directed the pipes of the director and rathole after completing the drilling work for the next week. On 13th of November, the drilling machines moved and the 14th well finished.

This pit will be significant to make Saskatchewan's deepest. The aquisters' pools will exceed 100 meters, with a vertical depth of 3,500 meters.

Marcia spoke about Pipeline News on November 9.

DEEP was created in 2010 He had "wonderful spurs", he said, where they would move a long distance, slowing down the financing. In recent weeks, 4 million dollars were invested in equity. They hired a drilling machine that is going on, but they have an option window.

It is good to drill for 25 days, well in that area. In this sense, they intend to cut 200 meters, on the ground floor, including nuclear power stations.

"Fortunately we will catch some core in a rope," he said. They try to penetrate into a 20-meter basement, which will provide the depth of the tools used to analyze the entire sedimentation column.

When Marcia, himself, while geologist sitting in the pits, DEEP recruited John Lake, an important geologist at Saskatchewan, who received a Pipeline News cover again and again.

This hole will be the first of the six, with three production wells and two injection wells. The pavilions are between 300 and 500 meters.

The initial starting diameter will be somewhat lower, at 7 inches below. The next production wells will be 9-5 / 8 inches.

That's why electric volcano electric pumps (ESP) pass through a large amount of water, from the Winnipeg and Deadwood formations that make up the last 200 meters of the hole. The Icebox formation, which overcomes the formation of Winnipeg, plays Caprock, as it does in the Aquistore project, about 29 kilometers east.

Aquistore carbon dioxide injects the storage and storage of carbon 3 Boundary Dam Unit in a deepwater aquifer, at a depth of 3,400 meters and two kilometers west of the central. SaskPower has already contributed $ 1 million to the DEEP project and shared with DEP with Aquistore.

Marcia stated in this case that Icebox works as a heat insulation.

Well, the pre-test resource, which is necessary for improving budgets, explained.

Marcia said well that "it is a similar deeply drilled in the 1980s in Canada's Natural Resources Resource Mobility." At 95 C temperature, but three days later, 126 C.

Therefore, the area is so attractive and why they are drilling so deeply. Marcia has stated that it is not a volcanic geothermal project, but rather a sediment basin. "Then you go deeper, get it warmer," said the heat in the middle of the earth.

"This is hot mining. It's a hot resource. Water is a bit of a bit of moving."

The plan is to drill the first well and then three weeks later to find its true temperature. For seven days they will poison the well with all the wells of production. They are preventing the formation of Mannville's future injection pumps.

At the end of March the exams will be fully reviewed. "If the first wells provide enough data to persuade a producer's supplier, we will go," said Marcia.

Then, after the spring of 2019, the plan will begin with production and injection pits to drill it as "double".

However, injecting wells will not go into the depth of production wells, but rather in lesser formation in Mannville, which is commonly used in regional wells. It is possible that this initial inert can be used as an injection. Pressure maintenance is required in the reservoir.

Each production will use a GNU, which draws approximately 1,340 megawatts of power. The total power generated by this project will be 10 megawatts, after the use of pumps and installation facilities, the net electrical energy will be 5 megawatts. It will be linked to a subscription to Bromhead.

Power production

The project's long lead is the same as power production facility.

On the ground floor, the organic Rankine cycle is used. While boiling a fluid in the workplace, the hot water extracted from the production wells transfers the heat through a heat exchanger and drives fluid into a gas (that is, boiling) and drives the turbine. A cooling tower reuses cooling fluid in the liquid phase during reuse. The water is pumped into the injection wells.

The concept of the system is almost identical and according to the Alliance Pipeline compressor stations that pass through Saskatchewan. The central heating recovery systems were installed in Kerrobert, Loreburn, Estlin and Alameda in 2008, each producing five megawatts of pure power.

Indeed, the use of DEEP's geothermal concept and its well-established technologies – production drilling and injection wells, using the heat of the Rankine cycling organic cycle, have created problems to attract funding, according to Marcia. There was nothing new, in itself. But this was a new technology application in the sediment basin, and especially in the Williston Basin, which is unique

The project can double the size, he said, but for a moment, the replication of the project can be added somewhat. It is scalable and repetitive.

The system will cool the water from approximately 120 C to 65 C, but this means that there is a lot of heat available. Its purpose is to produce electricity, but it does not feel that cucumbers, greenhouses or other applications may have the use of wastewater heating.

Two years ago, if things were doing well, Marcia said that it could have the power of the electrical network, according to renewable energy, up to 95% to date. He called it "the most attractive of renewable energies," and said he could compensate for coal.

Marcia points out that oilfield data, technology and processes are being used to establish renewable resources and without this industry, nobody knows that there is a geothermal resource here.
