Increasing Recovery in the Complex Reservoirs in the Al Shaheen Field, Offshore Qatar, by Mastering Reservoir Pressure for Large Scale Horizontal Infill Drilling

The giant Al Shaheen field offshore Qatar comprises six stacked carbonate and sandstone reservoirs developed with extended<br>reach horizontal wells. More than 130 horizontal production and injection development wells had been drilled up to end 2005<br>when implementation of a new large scale field development plan commenced. The new development plan, FDP 2005,<br>comprises 163 additional horizontal development wells from six existing and three new locations.
