Trajectory design for three radial channels with post-drilling inflow analysis and skin assessment.

Challenge

Area: Central Asia, Reservoir: oil sandstone Depth: MD – 19,482.61 ft, TVDSS – 18,819.52 ft

Solution

Based on the retrospective analysis of the well’s operating regime, the skin value prior to drilling the radial channels was determined as S = +2.83.

Production analysis (points – actual data, lines – calculated data)

The main wellbore trajectory has been loaded, a petrophysical reservoir model has been constructed, and parameters have been input for the calculation of the radial channel trajectories.

Results

The trajectories of three radial channels have been calculated, and the opened intervals have been identified.

Radial drilling completion of the reservoir - Channel 1, Channel 2, Channel 3

Inflow calculation from each radial channel and skin factor values after radial reservoir completion have been performed.
