Jr. Schofield et al., FIELD EXPERIENCE WITH MULTILATERALS IN THE IDD-EL-SHARGI NORTH DOME FIELD, QATAR, SPE drilling & completion, 13(1), 1998, pp. 12-18
This paper describes how one operator used the latest multilateral dri
lling technology to improve the profitability of the Idd EI Shargi Nor
th Dome (ISND) field, offshore Qatar (Fig. 1), Dual openhole laterals
have been employed to simultaneously exploit the Shuaiba A and B oil r
eservoirs. In each well drilled to date, the secondary wellbore has be
en cased off at the lateral junction following drilling of the fullbor
e lateral section. A mechanical junction has been used to ensure long-
term mechanical integrity and re-entry capability following completion
. To date, this technology has been used on five wells in the ISND fie
ld (IS-74, IS-75, IS-76, IS-77, and IS-80) Approximately 10 additional
complex-drainage-architecture wells are planned in 1997 to further de
velop this field.
