Design and Implementation of Horizontal Injectors for Liquid Injection from Gas Production and LNG Operations in Qatar

Water injection wells with horizontal openhole completions were successfully drilled and completed to provide enhanced<br>injection capabilities for waste water disposal. The impending start-up of several new RasGas Company Limited (RasGas)<br>LNG mega-trains will significantly increase the requirements for water disposal. Prior injection wells that have been operating<br>for several years are vertical or slightly deviated with cased-hole completions. In order to meet the future injection<br>requirements including increased capacity and sustained higher injectivity, studies indicated that horizontal wells with<br>openhole completions were required.
