... for a successful deployment of FeS dissolver in water wells. Iron sulfide scale presence in the wellbore is challenging to oilfield operators. Unlike other common scale types, such as Calcium Carbonates, FeS scale does not dissolve easily in Hydrochloric Acid (HCl) and the FeS/HCl reaction produces the dangerous...

... Abstract The Diyab Formation is an organic-rich carbonate rock with low permeabilities and is one of the first unconventional targets to emerge in the Middle East. Vertical and horizontal exploration wells were drilled during the past years with proven productivity in the United Arab Emirates...

... However, when drilling the exploration well, an over-pressured shale layer was encountered overlying the carbonate reservoir which was not anticipated. The over-pressured shale layer generated a low velocity interval that subsequently led to large depth errors compared to the prognosed depth...

... The Lower Cretaceous Thamama Group shelf carbonates are present across the entire Arabian Gulf (AlSharhan, 1985). In Sharjah, UAE, the Aptian – Berriasian age Shuaiba, Kharaib, Lekhwair and Habshan formations of the Thamama Group are present in the subsurface (Error! Reference source not found...

... of the reworked carbonates derived from the eroded C Formation as our conclusion. Materials and Methods Abstract Reworked carbonate caused by the major erosional event of the "Turonian Unconformity" is considered to be distributed around the eastern part of Abu Dhabi, UAE. During 2021-2022, new wells...

... steps, and present field data examples from a structurally simple clastic setting and a complex sub-salt environment. The latter, in particular, makes differentiating net versus non-net in pre-salt carbonate reservoirs a challenging problem when using narrow azimuth streamer data. The challenges include...

... as lessons learnt from other CCS campaigns. The evaluation for the well design and construction was conducted to identify potential gaps lacking in the CO2 injection design in offshore carbonate environment. From the identified injection location, evaluation criteria were finalized to assist in decision...

The well data based geological model suggests that initially porous rocks (presumably grain-supported carbonates) encompassed polyphase sulfate cementation during recurrent subaerial exposure in which pores and grains were recrystallized sometimes completely too massive, tight anhydrite...

... Abstract There are a limited number of studies and exploration cases for a "reworked carbonate" in Abu Dhabi, although these sediments are composed from some large oil and gas fields around the world (e.g. Poza Rica oil field in Mexico and Ruby gas field in Indonesia). In this study, we focused...

The Lower Member is predominantly evaporitic, becoming more argillaceous carbonate and shale –bearing in the the Middle Member with comparatively less anhydrites. The Upper Member contains mainly anhydrites with interbedded shales...

... It is well known that the formation of calcium carbonate (CaCO 3 ) scale is largely determined by the concentrations of calcium and carbonate, pH, temperature and pressure. The solubility of CaCO 3 decreases with increasing temperature and reducing pressure, thus resulting in increased scaling...
