Doha: Total’s large-scale 4D seismic acquisition survey, which started on June 1 in partnership with Qatar Petroleum (QP), has successfully ended.
The two-month survey was conducted on Al Khalij field (Block 6), operated by Total, 130km off Doha coast.
The main aim of the survey was to better understand production mechanisms at stake in Al Khalij and further enhance oil recovery and reservoir management of the field.
The full-field survey was decided after a pilot acquisition was successfully performed in 2012. Data acquired will enable better capturing of changes that have taken place in the reservoir of the field since 1999, when the initial baseline survey was conducted. Five vessels were used for the survey. Safety was given utmost importance, with zero recorded incidents.
An environmental impact assessment was also conducted and mitigation measures were ensured. An example of the measures taken was to have a marine mammal observer on board the vessel at all times to protect mammals and marine turtles.
Soft start shooting was also undertaken to ensure mammals will be outside the seismic survey area during shooting.
“The operation was a great success, as it was achieved safely without any accident and impact on the environment. It was completed faster than expected. This is a milestone project as it is the first time such a survey was conducted in Qatar, and we are proud to have partnered with QP on this.
“The survey is a clear illustration of our commitment to operational excellence on the field,” said Guillaume Chalmin (pictured), Managing Director, Total E&P Qatar and Group Representative.
Following the acquisition phase, data collected from the survey will be processed and interpreted, a process which will take one-and-a-half-year to complete. The Peninsula
