Published: April 2023

The lithologic and petrographic studies of the Mishrif and Kifil formations in Amara oil field in wells AM11,AM9, AM5 was revealed that the Mishrif formation consists of limestone and dolomitic limestone. While the Kifil formation is consist of the anhydrite and mud-dominated limestone.
The skeletal grains of Mishrif formation includes variety of benthos foraminifera, bivalves (Rudist) ,corals , stromatolite, algae, ostracods, gastropods, echinoderms. Non-skeletal grains are rare and authegenic minerals of pyrite and iron oxide are present. The rocks of the formation are affected by diagenesis such as dolomitization ,dissolution and recrystallization. The Kifil formation rocks do not have any skeletal grains and affected by recrystallization only .
The microfacies analysis of Mishrif formation reveals that the formation consists of: mudstone, wackestone, packstone, grainstone and boundstone deposed in the fore environments extend from for reef, back reef to: open marine, reef, shoals platform margin, restricted environment. The Kifil formation divided into tow lithological facies these are limestone and evaporite and we recognized mudstone microfacies only deposited in restricted environment and represents the Mishrif reservoir cap rocks .
The research illustrated that the upper contact of Mishrif formation is gradational and conformable with Kifl formation with evidence from a gradual changes from limestone to anhydrite. In this study was considered the evaporites and limestone to Kifil formation. The Kifil formation is presence by thickness (7m) in the Amara Oilfield .

Published: April 2023

Groundwater is an important resource in Halabja Said Sadiq sab-basin, Sulaymaniyah district for agricultural and other uses. Continuous dramatic extraction of groundwater from legal and illegal wells led to a severe decline in the water table for the last thirty years. The objectives of this study are to delineate the groundwater productivity zones by combining the geographic information system and geoelectrical survey, which serves to recognize the locations of good groundwater storage and recharge zones. The Halabja Said Sadiq sub-basin has been selected as a case study to delineate the groundwater productivity zones. Four geoelectrical resistivity profiles conducted with electrode spacing 10 m and the length of the profiles is equal to 710 m. Themes such as hydrogeology, land use/land cover, topography, drainage density, soil type, slope, lineaments and rainfall maps are created. The thematic maps made with GIS platform and appropriate weights put to the attributes taking into account the influence on the storage potential of groundwater. The results of geoelectrical profiles revealed that the aquifer thickness is 150 m. Three zones of groundwater potential delineated which are low, moderate and high and cover 33 %, 24 %, and 42 % of the total area respectively. Spatially, the highest zone is located along with the Quaternary deposits which characterized by high lineament density, low slop, and pediment deposition
The output of the groundwater potential model is verified by testing the discharge rate of the existing 580 wells. The results are revealed that most of the high yield wells are located within the high groundwater potential zone. Results of such verifications proved that the groundwater productivity areas recognized by GIS (AHP) and geoelectrical techniques are dependable and practical.
