Walekum Assalam,

Thank you for sending your question.

All these formation belong to Early Cretaceous Lower Goru formation and have been found in the adjacent area of Hydrabad, Badeen and Sanghar, in the wells drilled by various operators including OGDC and Union Texas. However these naming classifications have not yet been officially designated by the Stratigraphic Committee of Pakistan and are considered as informal units which represent certain lithofacie. There is no published data in public domain which has produced high resolution stratigraphic classification and age, therefore all these informal units belong to early Cretaceous age.  

Hope this answer helps.
