Environmental Baseline Study - Al Shaheen oil field, Qatar

Return mosaic

CLIENT: AE COM

YEAR(S): 2017

LOCATION: QATAR

MISSIONS:

  • Video transect
  • Characterization of the seabed substrate types (sand, mud, clay, rock, etc.)
  • Visual assessment of sediment texture
  • Qualitative description of observed benthic assemblages or epifauna communities
  • Identification of macroalgae and benthic species
  • Identification of fish species

BACKGROUND: 

The Al Shaheen field is located in the Arabian Gulf approximately 150 km north of Doha and 90 km north of Ras Laffan, State of Qatar. This is among the world’s largest oil fields. During the last two decades this field has been producing oil and it currently produces around 40% of Qatar’s crude oil, at around 300,000 barrels per day.

As the transition of operators of the Al Shaheen oil field takes place, NOC conducts an update of an existing Environmental Impact Assessment (EIA). As part of these works, NOC requires Environmental Baseline Assessment (EBA) works which includes sampling and analyses of water and sediment (including sediment samples for macrofauna) taken at multiple stations, and an underwater video seabed surveys. This survey (EBS) will also provide a baseline for the proposed Field Development Plan (FDP) for NOC to feed into the subsequent Environmental and Social Impact Assessment (ESIA).

NOC entrusted this Environmental Baseline Assessment to the consortium formed and supported by AECOM Middle East Limited (AECOM). Créocéan with Horizon had in charge the underwater video seabed since the operational work to the reporting. This task was conducted from the supply vessel TOPAZ Rayyan which is owned and operated by TOPAZ Marine. And the underwater video seabed survey was conducted which video and photographic data were collected with a Remotely Operated Vehicle (Seaeye Panther 90S ROV Systems) from Horizon.
