The Bedouin guide Khamis ibn Rimthan helps exploration
Early American geologists rely on Bedouins to guide them from one place to another. The most famous guide is Khamis ibn Rimthan, from the Ujman tribe. His expertise becomes indispensable and his cross-desert navigational talents leave the geologists awestruck.
First plane is used for aerial surveys
A Fairchild 71, specially modified for long-distance flying and aerial photography, arrives in Jubail in 1934. The plane drastically reduces the time it takes to map the concession area which is the size of Louisana and Texas combined. Dick Kerr, the plane's pilot as well as a geologist, helps map the bulk of the concession in 1934 and 1935.
