Kuwait is targetting an output capacity of 4 million barrels a day in 2020, the head of the Kuwait Oil Co. said Wednesday.

In the short term, the official also said he expected a slight increase in the country's output to cater for additional demand in the summer.

The remarks from the key member of the Organization of Petroleum Exporting Countries come amid expectations markets will need more oil from the group in coming years.

Speaking at the World National Oil Companies Congress, Sami Al-Rushaid, chairman and managing director of state-owned KOC, said the country has "enough reserves to increase capacity to 4 million barrels a day in 2020 and maintain it [at that level] to 2030."

He later said that would make a capacity increase of 700,000 barrels a day from 3.3 million barrels a day today.

Al-Rushaid said the Gulf state intended to fulfill this goal by using new technologies to improve productivity, such as enhanced oil recovery.

He also said the country is developing its heavy oil reserves, expecting to have 60,000 barrels a day output in 2016 in this category of hydrocarbons and have production capacity of 270,000 barrels a day in 2030.
