For underground hydrological survey: borehole drilling.

Considering the present situation in the country, it's nt advisable bringing in terrameter from abroad.

I ve some locally fabricated ones at hand and dey work just fine. Dey go for 400k,650k.
I ve a Chinese product too wc goes for 3.3m.
You can contact me for more enquiry.

how do a bsc. physics get into oil and gas

I need something like this

MoyoGENERAL:


Most times we don't use best design but OPTIMUM design for the specific target zones. Having said this, there are so many other factors to consider before selecting which completion strategy to employ to produce the hydrocarbon in the zones.
Cost, available technology, outcome of drilling challenges, HC properties, completion material integrity, etc. Nevertheless, I will try to analyze the 3 different scenario, state there pros and cons.

Single String: This is more or less the best option among the three, offering a more conservative measure towards field development. No much technology is required, cost-wise it's tolerable, however, in the long run, you spend more years producing from the reservoirs, thereby increasing your OPEX over the years, ultimately affecting your NPV. In term of safety, it's better too, cos of less corrosion outside the tubing and inside the casing due fluid production. Aside from all these, most times drilling is plagued with several challenges, where you have to use multiple intermediate casings, hence reducing the ultimate size of tubing to be used for completion, in a case where you've drilled in a troublesome interval( salt, high pressure, swelling shale), the allowance you may have for a tubing may not be up to 5.5 inches. Now imagine putting two 2.375 inches tubing in that with tolerance limits, it is almost impossible and unsafe. In this case the best is a single string( may be 3.5 inches) to deploy and produce the HC.

Dual string: Yes, this is good if less drilling problems were encountered while drilling impacting hole tolerance. Aside from the CaPEX of additional tubings and other surface networks, you tend to recover your HC faster meaning less OPEX in the long run. But to judge from the standpoint of economics, you will still have to consider other factors too like the amount of HC recoverable with the additional costs of the completion materials with there depreciation etc.. However from a rough quick view, this should yield more NPV for a robust reservoir. Nevertheless, the technology here is higher and complexities can abound downhole in terms of materials integrity due to tubing corrosion, more safety issues may abound especially due to pressure build up behind tubing for the reservoir at the top where HC is produced via the casing-tubing annulus, a gas flow can even be more dangerous to the wellhead.

Triple String: 3 tubings! Configuration complex than that of single and dual string. And believe me, the less complex your well, the better! Most Production Technologist will agree. I haven't seen this sha, cos it's not common due to the fact that final hole size after the drilling campaign may not allow such bearing in mind tolerance limits and opportunity to install other download equipments. The safety issue here is the fact that packer integrity will be susceptible to continual compromise, and there is high tendency of underproduction from one of the pay zone. Imagine a pay zone with a good productivity index, no near well bore damage, good permeability even in darcies, yet the maximum tubing size you can use is 2.375 inches just because you want to produce 3 at same time, when sensitivity study is indicating to you that you can increase tubing size and get more production. The key issue here will be the complex production system and difficulty during workovers( when need arises)


You know these are just brisk analysis. As a PTECH, I can choose to use a single 3.5 inches tubing and perform sensitivity analysis to see how well I'll produce in terms of well deliverability, choose an optimum flow rate at each phase during HC production in the different pay zones. This might even be better than using three 2.375 inches tubing differently yet simultaneously to produce from the 3 zones. So aside from all the cost, economics, tech, it's also the work of the P-Tech who will manage his baby all through the (well) lifecycle and see what's best for it.

For me, I'll advice you to to stick with SINGLE String. However it still depend on other factors listed here and even not listed here to ensure robust decisions are made as regard the optimum completion plan.

I hope this helps.

Shalom

Thanks a million. This was great though it came a Lil late. Thanks once again

Hello house.
Please what's the deepest and shallow oil well in Nigeria and in the world?

Strictly for Geophysicists, Geologist, Petroleum Engineers. Let's discuss the future. In terms of career development, job prospects, also we will be discussing about various oil and gas activities in Nigeria.

Anyway, let me start by introducing myself, my name is Imagwe Marcus, a graduate of geophysics. All contributions are welcome. The future belongs to those who are well prepared for it. Thanks and God bless.

Nice Thread.

Good day senior colleagues and happy Christmas to all,please I'm a 300lvl geology student,SIWES I.T training commences around February 2017,I really need a place for the training,stipends/monthly salaries not overly important,though I could be better with them anyways,location could be anywhere in Nigeria,I really appreciate any help rendered,Thanks.

making 2.1 (mostly but not always above 4.0)

buy the Msc form (around 20,000)

write the aptitute test and pass.
Come for ora interview and pass.
spending the controversial #2,300,000.00 which i still find very hard to believe even if na the whole uniport i wan buy, like my friend REDBENSON said
i also heard dat you can apply for scholarships (though for those with Almighty Bsc GP probably 1st class)

that is what i am told, though i will still verify during my NYSC period, because i have been having nightmares ever since i heard 2.3 million naira inshort telling my dad about the amount is an easy way to make him laugh so loud, i may use that amount to make him laugh this December.

Gozie=Dad Happy xtmas
DAD=wish you the same my son
Gozie=Dad, i want to do my Msc in Uniport
DAD=alrite, that's very good..i heard it is a very school
Gozie=But Dad, there is a problem, the school fees is...
DAD=I told you that school fees is not the problem, i can single handedly train you even to Ph.D,, so tell me the amount.
Gozie=The school fees is 2.3million
DAD=What!!,hahahahahahahah
Gozie=why laughing Dad.
DAD=No, my Doctor told me to always laugh especially when talking with somebody that is not serious

So how did it go? Did you later go to IPS? I've had the dream of doing my MSc abroad for a while. Now I'm seriously considering IPS. Hoping to get a ptdf scholarship. Cheers.
