Protecting
Water -- Safeguarding water is a high priority in Ghana.
Locals explained that this well is surrounded by elaborate
stonework for two reasons: to keep surface water from leaking
into the well and to provide run for spilled water. |

In August of
2000, Jim McDonald, vice president of Northeast Water
Production Inc. in Sterling, Mass., and I boarded a plane for
Ghana, a small country on the western coast of Africa, to
commission a Hydro-FracŪ rig and train a crew how to operate
it. The Hydro-FracŪ rig was purchased by Mensa Nunyuie, owner
of Kingaka Co. Ltd. in Ho, Ghana. For some time, he had been
working with a Dutch consulting company on a project called
Volta Region Community Water and Sanitation Program. The basic
idea behind the project was to keep the villagers from moving
to the overcrowded cities by providing them with safe drinking
water and sanitation. Kingaka Co. Ltd., along with a few other
companies, had been drilling the wells for this project and
obtaining less than satisfactory results. In other words, no
matter how many wells they drilled, they couldn't seem to get
enough water. While in the United States, Mensa learned of a
technique called Hydro-Fracking and proceeded to spend the
next five years researching the technique and trying to sell
the process to his employers. In late 1999, things finally
started to move forward.

of the Land
Most
villagers in Ghana have a very limited supply of water. They
usually spend the better part of the day collecting water from
surface sources. In some villages, I witnessed families
walking as many as five miles to a muddy river with buckets on
their heads to collect water. In one instance, I saw them
scooping water from puddles, and in another instance, I saw an
elaborate rainwater collection system where the rain was
collected from the roof of one of the huts.
The bedrock formation in Ghana is much the same as it is in
the northeastern United States. Most of the formation is
comprised of granite, schist, mica, quartz, etc. There are two
rainy seasons in most of the country, so there is ample
recharge to the bedrock. The project dictates a maximum hole
depth of 60 meters (approx. 200 feet). A minimum of 13.5
liters (4.5 gpm) is needed for a successful well, which will
supply a village of 300-350 people. If a well was drilled and
did not produce the needed volume, it was immediately
backfilled and abandoned.

No
Water Wasted -- Following each job, the villagers
gather to collect the discharge water, allowing none
of the precious resource to be squandered.
|
|
All wells, drilled with sufficient yield, are cased to the
bottom of the overburden and a minimum of a hand pump is
installed in them. In a few places where the yield was
significantly higher than the minimum 4.5 gpm, solar powered
pumps were installed that fed large cisterns and gravity fed
water to various spigots throughout the village.
| Trying
Something New
When Mensa
started to drill a lot of dry holes, he took it upon himself
to try the Hydro-FracŪ process on a few of the wells. He got
permission to leave some of the dry holes open, rented a Kyle
Skid Mounted Hydro-FracŪ system from a Belgian company that
was working in Cameroon, and proceeded to Hydro-FracŪ 35
wells. One well was in the village of Adaklu-Anfoe, a village
where 10 previous wells had been drilled, and not one produced
a sufficient amount of water. Out of those 35 wells that were
Hydro-Fracked, all were successful in obtaining the minimum
amount needed for a hand pump. The success ranged from a 75
percent increase to over a 1,000 percent increase, with the
average being between 350-400 percent. That breaks down to an
overall increase in yield of 3 gpm to 45 gpm. |

Reaching
the Site -- Ghana's trying terrain makes it
necessary to mount the Hydro-FracŪ rig on an
all-wheel-drive army transport truck. Getting the rig
to each site was just one of the challenges the team
had to overcome. |

At this point, Mensa knew he had a good idea, but the law
about abandoning the well wasn't about to change just yet.
Mensa decided to visit us at Kyle Equipment Co. in Sterling,
Mass. At that time, we had a used Hydro-FracŪ unit complete
with dual two-speed Hydro-FracŪ pumps, a packer inflate
system, and a 12,000-pound hoist perfect for his application
and ready to be mounted on a truck. Early in May of 2000, the
Hydro-FracŪ unit was loaded onto a ship, and in August, Jim
and I headed for Ghana.
The first village we visited was Adaklu -Sofa, a small
village in the Volta Region, Ho District of Ghana. There were
two wells in this village that needed to be Hydro-Fracked.
Before we could Hydro-FracŪ the wells, a few problems needed
to be addressed. These were problems that you just don't run
into here in the States. For one, the suction and discharge
hoses used to connect the water supply through a contractor's
pump to the Hydro-FracŪ rig were standard pipe thread
connections, but the pump they purchased had imperial threads
on them. Another problem was the packer inflate line which
comes with standard JIC fittings needing 1/2-inch and
9/16-inch wrenches. Mensa's problem was that only metric tools
are available in Ghana, and since the fittings are a softer
steel, the small difference in size between a 10mm and a
1/2-inch is enough to round off the corners of the fittings.
The third obstacle was finding a 24-inch pipe wrench. All this
equipment, which can normally be found in your local Sears or
Wal-Mart, just isn't readily available in some parts of the
world. Pipe wrenches were eventually found, and the 10mm
worked until we could get 1/2-inch and 9/16-inch wrenches sent
from the States, and the improvisational skills of the Kingaka
employees headed by Emmanuel Ahiayibor were incredible. They
fixed problems and completed jobs with whatever was handy.
Once we got the tool problem taken care of, the only
problems we faced were logistical. Trying to get to a lot of
the jobs was tough; this is why the Hydro-FracŪ rig was
mounted on a huge all-wheel-drive army transport truck. In one
case, we had to follow a footpath for almost a mile to the
village. We had to tow the water truck in the entire way.
Which brings us to the other problem - getting water to the
jobs. Finding a local water truck is extremely difficult, and
finding one that can go off road is almost impossible. The
truck that we were working with carried 4,000 gallons of
water, but once it left the road, it got stuck every time. The
solution was to get a tractor towing a smaller tank behind it,
but it had to travel so far to get the water, it made the
tractor impractical. However, the Kingaka crew managed to find
a way to get the water to the site every time.
At the first well, Jim and I ran the rig and pointed out to
the Kingaka crew what we were doing and why. As the jobs went
on, Jim and I had less and less involvement in the actual job,
until we were finally just observers like rest of the
villagers.
As we proceeded with the jobs, all the signs like large
pressure drops, change in color of the discharged water, etc.,
were present. For the most part, the average pressures were
about 800-1000 psi maximum for the first set, dropping down to
about 300-400 psi, and 1700- 2200 psi maximum for the second
set, dropping down to 500-900 psi. There were a couple of no
breaks, maximum pressure build with no drop off, and a couple
of wells where only one set was possible because of well depth
and casing depth.
After each job was completed, no water went to waste. The
villagers would all line up and collect the discharge water
and the remaining water in the hoses. The villagers also came
to help every time a truck got stuck. In all, we completed 12
wells in seven days, which is good by American standards,
especially considering all of the problems we faced initially.
| Celebrating
Water
As we were
heading in and out of Adaklu-Sofa, we had to go through the
village of Adaklu-Anfoe. There we noticed the village was
apparently getting ready for a ceremony of some sort. We would
later find out that it was a commissioning ceremony. The one
well that Mensa had Hydro-Fracked in the village had increased
to not only passing, but further to an extent where a solar
powered pump could be installed. The ceremony, which we
attended, was an extremely big event. The people attending the
festival ranged from common villagers, to the surrounding
villages chiefs, to members of parliament. The ceremony
included a ribbon cutting and a blessing by the village chief.
After the ribbon cutting, we were invited to stay for the
party, which included music, dancing and a speech by the prime
minister. The event, which, let me remind you, was possible
because a well finally produced water, was televised to the
nation. That is how important water is in Ghana, and we
sometimes take it for granted here in the States. |

Festive
Reception -- Local village chiefs celebrate the
success of a well at a commissioning ceremony in
Adaklu-Sofa. The event was so significant that it was
broadcast on national television. |
