In some years to come a large proportion of the offshore
platform will need to be decommissioned. Can we discuss the health, safety, environmental and cost issues as
regards the operation,disposal, and any potential re-use of decommisioned plants and structures?
These blogs are the perfect way to develop many and various safety discussions covering large areas of industries. As a student of an MSc in Oil and Gas Engineering I would like to develop a discussion related to safety issues in the sector of well drilling and generally the operations associated with this activity.
Transportation and distribution are two sectors of industry which should also be mentioned regarding safety issues applied there. Many incidents are indicating that there is a need of some improvements in practices applied so far. So, my suggestion is to discuss this topic further.
Reliability Block Diagram (RBD), Fault Tree Analysis (FTA), Event Tree Analysis (ETA) and Bayesian Network have been said to be useful tools in the Safety and Reliability class. How reliable is this? Can we discuss if this is true.
People say that by 2040 the energy landscape
will definitely change. It is also believed that by 2040 the global energy demand
will be increased by 30% while the population is
expected to be increased by 25%.
How will these affect the industries? What are the risks associated? Undoubtedly,
fossil fuels will remain the world's
major sources of energy (at least 50% t of the world's energy supplies). That
Usually
when the well reaches its economic limit the operator plugs and abandons it.
But the risks and hazards that can happen due to this are neglected. Gas leak
from one of the plugged wells of Elgin gas field shows that abandoned wells can
cause serious threats. With this incident which occurred recently shows that, accidents
can happen even if we have methods to completely seal or plug a well. No human
life was threatened by this accident, but oil and gas leaks from the abandoned
wells can cause serious environmental impacts. Reason for the gas leak in Elgin
field was due to the outdated plugging method used to seal the well by Total.
In this energy demanding world the need for fossil fuel never declines. Depletion is an unavoidable part of hydrocarbon production and all the reservoirs around the globe faces this. Depletion due to hydrocarbon production can also pose threats that can even make a scar on the earth's face.
1) Land subscidence
2) Fault reactivation
3) Earthquakes
4) Casing damages
5) Formation damage
