I spent two years flying Twin Pioneers and Pembrokes around Oman and the Trucial States in 1959/61. Oil survey groups from the Iraq Petroleum Company used to mark out strips using graders and use them for a month or so before moving on. The strips sometimes had names, sometimes numbers. Supplies were flown in from Beirut by Avro Yorks. Information on the state of the strips was not kept up to date. Some were near the mobile camps, others were some distance away and unmanned. I have enjoyed the odd pint of ice cold Red Barrel when we dropped in unannounced for a spot of lunch!
