Response of foraminiferal facies to transgressive-regressive cycles in the Callovian
of Northest Scotland, Journal of Foraminifera Research, 3, 324-349.
As with Well 143 the new well is initially targeting Jurassic Callovian
sands at a depth of 2,200 meters with a secondary objective in the Cretaceous Valanginian limestone at a depth of 1,900 meters.
The increase in kaolinite contents in the Callovian
suggests a subtropical humid climate with less prominent seasonal droughts and a higher input of siliclastics into the basin accompanied by a higher nutrient influx (Fursich et al.
It is Callovian
and Oxfordian in age and reaches a thickness of more than 300 feet in the basinal area between the Ghawar and Khurais Fields.
He added that during the Middle Callovian
165 million years ago, much of Europe was covered by a shallow sea, creating a chain of large to small islands.
The LGA-1D tested a three-way dip elongated faulted closure in two Dogger limestone formations - the Callovian
and the Bathonian.
The obligation to assess the Callovian
reservoir through sidetracking well-09 has been deferred until 2017 however a new well location is being reviewed to meet this obligation.

Radiolarian associations are allocated to Callovian
, Upper Jurassic, Lower Cretaceous and Santonian (Galli, 1977; Schmidt-Effing, 1979; Baumgartner, 1984).
