The company also said that it expected to post additional well write-offs in the range of $100m-to-$200m compared to the fourth quarter of 2018.

Production at Shell's integrated gas business was seen at between 920k and 970k barrels of oil equivalent per day, with LNG liquefaction volumes at between 8.8m and 9.4m tonnes.

Provision updates for decommissioning and restoration obligations were expected to have a negative impact on earnings in the range of $100m-to-$200m.
