Reef

A type of reservoir trap composed of rocks made of the skeletal remains of marine animals.

Refining

The manufacturing process that turns crude oil into different petroleum products.

Reformer & Catalytic Reformer

The reformer is the first part of the ammonia-urea and methanol production process. The natural gas feedstock is combined with steam and converted to carbon dioxide and hydrogen prior to being further processed into ammonia or methanol. In a catalytic reformer a catalyst is used to aid the conversion process.

Reservoir-Rock (Geological)

A porous and permeable rock e.g. sandstone, limestone or dolomite, which contains petroleum in quantity.

Reserves

The unproduced oil or gas in place in a formation that remains but is still recoverable.

Resistivity
