MDOIL Limited is a private exploration consultancy established in 2005 with the purpose to assist Governments secure international investment to open up neglected oil and gas exploration acreage and frontier acreage.

This has been achieved by helping build new investment vehicles  and companies (EAX, BMEL, CaribX, Adamantine Energy, Cluff Natural Resources), through the analysis and digitisation of vintage data sets; providing new geochemical and geological analysis and insight; introduction of new technologies (e.g. GraveX/Gradiometry) and application of new petroleum geological thinking. This has included the opening of the lower Mesozoic source system of the western Indian ocean, determining the origin of the hydrocarbons in the North Sumatra basin, recognition of the Upper Jurassic Durban basin source system and expansion of the Cretaceous regional source system within the greater Caribbean region.  

MDOIL is owned and managed by Chris Matchette-Downes.
