Four shallow horizontal wells were drilled from Platform C in Dos Cuadras field offshore California to recover reserves inaccessible with conventional drilling techniques. The wells had true vertical depths (TVD's) ranging from 746 to 989 ft with total horizontal displacements from 1,613 to 3,788 ft. The wells had horizontal displacement TVD ratios up to 3.95. The targets were unconsolidated, high-permeability sands. This paper details well planning, drilling, and completion.
