The Manifa Drilling Team set a new record in December when it finished drilling the longest well in Saudi Arabia to a total depth of 32,136 ft (± 9.8 km) and completed a horizontal power water injector across the Lower Ratawi reservoir.
A [Canada's] Precision Drilling rig did the work on the Manifa well, [...]. The same drilling team set an earlier record while working on the 30,850 ft (+9.4 km) Manifa well.
Discovered in 1957, Manifa field is in shallow waters southeast of Tanajib, about 200 km northwest of Dhahran [please see map of oil and gas fields in Saudi Arabia, here -- D.R].
The [Saudi Aramco's] development strategy of Manifa is based on optimum use of onshore drilling. Instead of developing Manifa completely from offshore platforms, it is developed from 27 drilling islands connected by a 47-km long causeway, in addition to 16 onshore drill sites and 13 [offfshore] platforms.

Extended-reach wells, such as the two mentioned above are required for optimum field coverage. Read more
(During the May 2010 Offshore Technology Conference, Zuhair Al-Hussain, Aramco vice-president, drilling and workovers, said production from Manifa will start in mid-2013 but will not ramp up quickly to the original target of 900,000 b/d of Arab heavy oil (OGJ, May 10, 2010, p. 19). Also, please see my updated post on Manifa -- "Manifa to Yield 500,000 b/d by 2013 and 900,000 b/d by 2014 -- Aramco," here. Houston-based Parker Drilling, operator of the Yastreb Rig for Exxon Neftegas Limited, set world record for extended-reach drilling: Sakhalin's Odoptu OP-11 well reached a total measured depth of 40,502 feet (12,345 meters or 7.67 miles)---please see my post here. -- D.R.)
