As success of an E&P activity remains ambiguous until the discovery of an oil resource, most of the E&P companies are engaged in rental contracts as opposed to purchasing of the new rigs.

The rental contract involves insurance premium with specific investment return laws. Nabors Industries Ltd, Precision Drilling Cooperation, Patterson-UTI Energy Inc., and others are leading rental companies in the Mobile Servicing Rig Market.
