The oil price is fallen from 107$
to 45 $ , last update oil commodity price is 57$, one year forecast is 60$. How
does effect the economy? A lot of people could say, it is good if the oil price
is falling down, Economy take advantage, might in short term could be true. But
in one-year term i will not be so sure.
It is important to analyse the
impact on Oil industry. Because from this impact will depend the next forecast
oil price and future economy shock.
Let's analyse the Oil industry and
oil well drilling cost:
We divide in offshore and onshore
activity
Impact cost of Carry out Offshore
drilling activity:
Deep water: drilling ship and Sami
sub up to 12.000 feet of water
Daily rate cost of drilling ship:
500.000 to 800.000 $/day
Sami sub: 250.000$ to 500.000$
Jack up - up to 400 feet of water
Daily rate 150.000 to 250.000 $
Onshore activity:
Daily rate of land rig from 35.000
$ to 100.000$/day
The cost is just estimation the
variable of daily rate depend of which location performing drilling activity
and the complexity of drilling process.
Let's calculate to realize the oil
well with drilling ship considering worst case 800.000$/day
Forecast time to realize the well 2.5-month
75 days.
75 days x 800.000$ = 60.000.000$
Estimate production BARRELS/DAY
= 2000 BBLS
APPLIEND A STUPID CALCULATION: 2000 X 107$= 214000 $/DAY
How many days to pay off the well?
Drilling cost/daily production: 280 days
If we apply the same calculation with 58$ something change:
2000 bbl. x 58$ = 116.000$/day
Well Pay back after: 517 days - 1,5 year
But if applied the properly calculation the days will be much
more as below, if we take in consideration other factor:
A well is said to reach an "economic limit" when its most efficient production rate does not cover the operating expenses, including taxes.[5]
The economic limit for oil and gas wells can be expressed using these formulae:
Oil fields:
![{EL}_{oil}=\frac{{WI}\times{LOE}}{{NRI}[{P_o}+({P_g}\times{GOR})/1,000]\times(1-{T})}](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_t6ciNEtiyQOKXC6LUeg0cr7ypXAMfEgCMsbHcou5JmQNsTZtOEBTxy6EWnpr0AoRDY0iX2pDZqKm3JYmsktBnaGrfvA_16IiGQGksqEAzZ-Ttrz81j8zE6kexvPqBwS1Tyu5L4vfCLLgU7iUt-rg=s0-d)
Gas fields:
![{EL}_{gas}=\frac{{WI}\times{LOE}}{{NRI}[({P_o}\times{Y})+{P_g}]\times(1-{T})}](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_s9UHvQzNF98ag1Wt9LX_656_6Jb6K4NJZhL-G9JZDt8Plk9K1WgmHMjaxV3i62DyUzBc4WvRWNs-xv1TVXPaYwLgYaYDUrwTZr0mwtEgBB7vz1PfRJCPSZoGFpPXdU06xRBseq8JquYDJbsgjWQg=s0-d)
Where:
is an oil well's economic limit in oil barrels per month (bbls/month).
is a gas well's economic limit in thousand standard cubic feet per month (MSCF/month).
are the current prices of oil and gas in dollars per barrels and dollars per MSCF respectively.
is the lease operating expenses in dollars per well per month.
working interest, as a fraction.[6]
net revenue interest, as a fraction.
gas/oil ratio as SCF/bbl.
condensate yield as barrel/million standard cubic feet.
production and severance taxes, as a fraction.

Gas fields:

When the economic limit is raised, the life of the well is shortened and proven oil reserves are lost. Conversely, when the economic limit is lowered, the life of the well is lengthened.
When the economic limit is reached, the well becomes a liability and is abandoned. In this process, tubing is removed from the well and sections of well bore are filled with concrete to isolate the flow path between gas and water zones from each other, as well as the surface. Completely filling the well bore with concrete is costly and unnecessary. The surface around the wellhead is then excavated, and the wellhead and casing are cut off, a cap is welded in place and then buried.
At the economic limit there often is still a significant amount of unrecoverable oil left in the reservoir. It might be tempting to defer physical abandonment for an extended period of time, hoping that the oil price will go up or that new supplemental recovery techniques will be perfected. In these cases, temporary plugs will be placed downhole and locks attached to the wellhead to prevent tampering. There are thousands of "abandoned" wells throughout North America, waiting to see what the market will do before "permanent" abandonment. Often, lease provisions and governmental regulations usually require quick abandonment; liability and tax concerns also may favor abandonment.
In theory an abandoned well can be reentered and restored to production (or converted to injection service for supplemental recovery or for downhole hydrocarbons storage), but reentry often proves to be difficult mechanically and not cost effective.
What reaction will have the oil
industry?
1) The first act it will be to
release drilling ship and semi sub to stop deep-water activity, explorative
well particle hit.
2) Decreasing the offshore activity
- releasing Jack up Rig
3) Shale gas activity will be hit
due to expensive drilling and production process.
4) Other expensive onshore activity
will be suspended.
5) All facilities and service
for oil industry will decrease the activity
What happen when the Rig is released?
I will make the easy example to
show the impact in oil drilling process in case activity suspended for long time,
describing team work and efficient of rig -which huge impact they have in cost
we call NPT - no production time - and in safety.
I take as example the land Rig:
Before start the Drilling activity,
Oil Company chosen the oil rig, then it has to be inspected, move to location.
Almost of oil Rig you noticed the inefficient issue only when you are drilling,
also the personal has to learn to work as team. As experience each rig before
become in compliance with general golden rules need 6 month some time more. So
the well you schedule to drill in 2 month, will be drilled might in 3
month due to the effect of NPT.
When the Rig is released the
Drilling contract has not interest to service it, also the personals will be
released.
But the time arrive the call, the
time to re-service the Rig, moving to location, start drilling, to recruit
staff with knowledge and experience and to train drilling team work as
professional team. Require 1 0 2 year before start in efficient manner oil
activity.
Without analyse other service, like
logistic, Service Company etc.
In Final if the price continue to
be around 55-58$ x 1 year at least, i predict in middle term the oil will rise
up to 100$, can reach also 200$/barrels.
The country like Saudi Arabia,
Qatar, middle east where the cost of drilling is less then other country, if
they continue to invest in drilling activity, they will have the great benefit.
In next future.
