Mega Protection

The proposed pipeline route was selected after years of feasibility
studies aimed at avoiding environmentally and socially sensitive
areas such as protected regions and zones of high population density.

In spite of the fact that at the UN level prima-facie, the world governments seem to be on the same page and have pledged to implement all or most international policy agreements, conventions, protocols, treaties on environmental protection, use of natural resources, climate change, biodiversity, renewable energy, green technology and sustainable development goals. Yet, primarily driven by their national economic interests, developing countries undertake such mega projects that have all the potential to cause environmental degradation, fragmentation of human and wildlife populations and result in undesirable accidents without precise assessment of their impacts on the environment, people, water resources, wildlife and habitat.

However, local communities, civil society organizations and environmental experts watch such developments with deep concern about the safety of all stakeholders and raise their voice through media to forestall the accruing damages in the project area.

With steady increase in the world population and ever-increasing demand for energy supplies, oil and natural gas pipelines have become a necessity to reduce the cost of their uninterrupted supply from source areas to demand areas. Notable examples of major trans-boundary oil pipelines include Kazakhstan-China pipeline (2798 km) delivering 142 million barrels per day from the Caspian Sea to Xinjiang, Key Stone Pipeline (2456 km) from Alberta, Canada to Illinois, USA, delivering 0.83 mbpd, Druzhba Pipeline (4000 km) that runs from Central Russia to northern Germany with a capacity of 1.4 mbpd, and Eastern Siberia-Pacific Ocean Oil Pipeline (4857 km) that transports 0.3 mbpd from Russia to China.

Crude oil usually varies noticeably in its density and volatility and may appear from a very thin and volatile liquid to a quite thick, semi-solid and heavy oil. As such, it can be categorized into four main types, i.e. very light, light, medium and heavy, on the basis of its viscosity and wax content. Transportation of heavy crude oil through long distance pipelines requires several pumping and heating stations installed at regular distances to keep its temperature high enough, up to 50 °C, to avoid precipitation of wax on the inner walls of the pipeline that reduces flow rate.
