This Day in History (1975): Records set at Safaniya
A 50-man team, consisting of 40 Saudis and 10 expatriates, set a new drilling record at Safaniya.
From the April 9, 1975, edition of The Arabian Sun
Drilling records were made in the Safaniya field by the Loffland ST-1 drilling team in February when they drilled two directional wells in 11 days or less to take second place in the Aramco Drilling Game competition.
The 50-man team, consisting of 40 Saudis and 10 expatriates, first completed Safaniya 146 in 11 days to break the existing record, then broke their own record by drilling Safaniya 188 in 10.5 days — it usually takes 12.5 to 13 days to drill a directional well.
Both wells were drilled as part of a development program in which approximately 100 wells will be tied into six-well platforms, in which one well is vertical and the other five “directional wells” slanted or deviated about 1,000 metres in all directions from the center.
The Loffland rig ST-1 and the Reading and Bates rigs L. M. Clark and W. D. Kent are currently working in the Safaniya field, which was the first offshore field to be developed by Aramco and is the largest offshore field in the world.
