The new discovery comes almost 50 years after ONGC began production in Mumbai High, which is India’s biggest oil field. It currently produces 205,000 barrels of oil per day (just over 10 million tonnes per annum).

Key Facts

In all, ONGC had tested nine objects or zones and all of them were found to be hydrocarbon bearing. The last object tested flowed 3,300 barrels of oil. ONGC is also carrying out further appraisal of discovery and has intimated upstream regulator Directorate General of Hydrocarbons (DGH). The new find will add to existing production capacity of Mumbai High in less than two years time.  It will help ONGC to maintain production levels from basin for a longer time than currently estimated.

Mumbai High

Mumbai High is ONGC’s flagship oil producing assets. It along with other small fields along western offshore have produced 16 million tonnes per annum of oil, which is 44% of India’s total crude oil production of 36 million tonnes. ONGC produced 25.5 million tonnes of oil in 2016-17, which will reach 28-29 million tonnes by 2019-20.

Tropical Cyclone Chapala hits Yemen triggering heavy floods

A rare tropical Cyclone Chapala has slammed into Yemen triggering heavy flooding and causing damage in coastal region of the war racked country.

The cyclone made landfall in the south eastern provinces of Hadramawt and Shabwa along the Gulf of Aden coast of Yemen in Arabian Sea bringing winds of speed more than 100 kms per hour.

Key facts

  • Indian Meteorological Department (IMD) has categorized Cyclone Chapala as a Category 4 equivalent storm on the Saffir-Simpson Hurricane Wind Scale.
  • It is believed that Cyclone Chapala is the most powerful storm that has hit Yemen in last five decades.
  • It is the second-strongest cyclone on record over the Arabian Sea, only after Cylone Gonu (2007).
  • The rainfall brought by cyclone has caused flooding of rivers which are usually dry causing destructive mudslides.
  • Earlier the cyclone had wreaked havoc on the island of Socotra, located 350 kilometers off the Yemeni mainland.

Cyclone Chapala was formed after a low pressure was formed over the Arabian Sea with deep depression intensity. The low pressure was formed due to record warm water believed to be associated with an El Niño event and low vertical wind shear.
