This study examines textural characteristics, carbonate, organic carbon and chemical
composition of sediment samples recovered in the nearshore region (~ 3–19 m water depth) …

Sandstone oil reserves are composed of a variety of clay minerals, including kaolinite, illite,
and chlorite. These clay minerals have a significant effect of reservoir quality. The upper …

In the Rumaila oilfields in southern Iraq, the Zubair Formation was deposited in a shallow
environment as three main facies, delta plain, backshore, and delta front depositional …

Tanuma and Zubair formations are known as the most problematic intervals in Zubair
Oilfield, and they cause wellbore instability due to possible shale-fluid interaction. It causes …

The Hartha Formation is the shallowest of the major Majnoon oil field reservoirs. It is a 120 m
thick carbonate platform deposit with an age of the Upper Campanian-Maastrichtian. It …

The vanadium geochemistry was estimated in the topsoil of Kirkuk, northern Iraq, and its
potential sources are forecasted by using multivariate statistical analysis as useful tools in …

Zubair Formation is the most productive reservoir in southern Iraq, which is comprised of
sandstones, interbedded with shale sequences and sometimes carbonate rock. It is an …

Wellbore instability in the Zubair oil field is the main problem in drilling operations. This
instability of the wellbore causes several problems including poor hole cleaning, tight hole …

The Zubair Formation is a prolific oil reservoir in several southeastern Iraq oil fields. The
formation comprises thick sandstones with interbedded shales and siltstones of Lower …

The petrography and geochemistry of clastic rocks from the Upper Cretaceous Terani
Formation of the Cauvery Basin were studied to decipher their intensity of weathering …
