Starting this business would cost how much?

Henrypraise:
once a well bore isn't productive, afta u av drilled deep n wide, pls abandon d borehole n move to a virgin land, drill deeper n wider till u get wat u want...

remember don't leave ur tools in d wellbore, just pack ur equipment n zoom off...

braveheart008:
I am into borehole drilling business in Abuja. You can contact me if you have any borehole to drill here in Abuja. My contact is 08158101071

Mrbigman1:
Anyway, I did my studies in the East, Anambra basin and in anambra state.

My project work was on geology and geophysic in the anambra basin, ( aguleri and environs)

I found out that water and portable water is scares in anambra state. And drilling is very expensive due to the terrain. Iron stone (consolidated iron band) and thick clay stone formation banding the Nanka sand which holds the ore.

From my research as published, aquifer that holds portable water in that area is about +/- 60m, but drillers should be wary of the mudstone and mud type should be put into consideration to avoid swelling and hence stuck pipe.

Temi011:


yea, in addition imo shales and enugu coal also trend to some areas of anambra state...in particular ifite, in awka. i got to know this from a geophysical investigation i did dere. and that is why drilling is very expensive dere.

you have to spend like 30m....this is because you only have sands from the top down to like 20m, after this, its coal/peat and shale you ll b drilling till like 300m....and as a geologist you know what it means drilling thr shale.

Kjnwancaro:



What type of formation do you have in that region

In addition, geophysical equipment such as ABEM terrameter from Atlas Copco, well logging equipment, as well as electromagnetic equipment for VLF measurements (Ronka Geonics used to be popular) could be quite useful.

Pump testing equipment, water level sounder and of course, interpretative software could make the your life easier in achieving your aim of precision and quick delivery.

ostopsmich:


Having all the required equipment will cost you nothing less than 70million unless Na hand dug borehole equipment you wan dey use which isn't advisable at all

Mrbigman1:


I beg do disagree with u. Wideness dnt have much to do with production. Ur quest is to fine clean and potable water. The size of UT drill bit or down hole tool depend on the kinda well u wish to hit. Only a self productive well like the artisian well will need size, but we'll u need to suck out with a pump dnt really mater, and remeber, u will case.

Finally, I always encourage people to run a geophysical survey before drilling to know what u re expecting.

Mrbigman1:


Wia ve u used these equipments? I am sure not in Nigeria for borehole drilling.

Larwin:


wow, where did u get this section...i am anticipating to hit that gravely sand around 300m and use the clay which is likely to be shale as a confinement. Drilling of this depth is not a small thing.

there ll be so much problem but from technical knowledge one can smoothly bypass them....one of the biggest problem to watch out for is loss of circulation.

Henrypraise:


I agree to disagree, d width of a borehole has everytin to do wit d anticipated satisfaction, caving in may occur, casing of well bore becomes expensive n wen casing isn't properly done, debris may fall in n contamination which may lead to fishy smells in wellbore...

infact all guys stay away from a overtly wide n deep borehole if u want to continuously enjoy fresh squirting of fresh water till old age...

Mrbigman1:



U barely get loose of circulation in shale or clay, u rather get swollen. Dis clay is still not compacted. So it's water content are yet to be expelled.

As for drilling, depend on the capacity of the drilling rig at ur disposal, 300 is a 1hr job.

Everything I mentioned I've used at some point in the past.

What it also means is when people scream inflated borehole contracts by Fashola I simply shake my head knowing people are talking from a point of ignorance.

We've not even spoken about installation of casings and screens (Johnson steel more expensive than pvc), requiring the use of cranes. Some projects require overhead steel tanks as part of the project scope, generator house, reticulation to a certain distance away from the source and even further use of a surface tank sometimes.

Projects vary but those geophysical equipment I spoke of at the beginning were routine equipment I used daily back in the day.

Larwin:


when sand overlays shale/peat, there is high susceptibility to encounter loss of circulation. are you saying a 300m sedimentary drilling can be done in an hr , well it cud b done in the oil industry, but in water industry...its not possible.

Mrbigman1:


Nice one, but using a sonic sounder which is radioactive substance in search for water and maybe a resistivity down hoke tool is something I thing is efficy. Dis is not germany Bro, it's Nigeria wia water is all over.

Knowing dat u ve to do water test to pick a potable water.

Make dem no go dey give people contaminated water oh. My hand no dey lol

Mrbigman1:


I repeat, the only play u get loose of circulation in clay is in a faulted shale. Passing through a faulted zone or region is rigorous and a soft green shale of 300 meter (900 ft) is not possible.

300 meter green shale can be done in 30min.
PDC bit perfoms better in shale. This is only possible with a high capacity drill rig.

I have drilled 5k meter well horizontal well.
3k TVD.

rusher14:


The sounder I mentioned isn't radioactive.

It's a simple probe used in measuring the water level within a well. It beeps on coming in contact with water and is ideal for measuring the static water level as the reel is graduated.

It's truly sad to see the standard of borehole engineering hasn't improved in Nigeria since I left it over a decade ago.

sonnie10:


Actually, I am prospective customer. The reason I searched for more information on borehole is due to the quote I got from some guys for drilling around that area. It was ridiculously cheap that I became suspicious. They said $700k total ( labor and all materials included)

Based on the dept in the chart I posted; about 200meters, they will need up to 55 pics of those 12ft pipes. When I checked, each pipe cost #10K. That is #550k already.

We have not even added the cost of sump, tank and Labour.

So, I called someone else and he said it wasn't possible for that price. But to my surprise, a neighbor just did his for #700k. My question is, how do they cut cost?
