Located in the south of central transitional zone of the Fula sub-basin

northeastern Muglad Basin

Sudan

the Fula N is a structural-hydrodynamic heavy oil pool with shallow burial depth

loosely cemented reservoir

high porosity and permeability

and active bottom water.These features make the CHOPS(cold heavy oil production with sand) a suitable technology for the development of the pool.Matching technologies

such as completion with bigger size casing and long sand pocket and protection of interbedded shale in thick oil layer during perforation

are adopted

achieving an average daily production of more than 100 m

3

from single well.In wells with severe sand problem

the production technology known as "limited sand control" is used to reduce the ope-ration cycle and cost

and enhance the economic returns.
