... Abstract Severe Asphaltene deposition is encountered in some wells drilled in newly developed reservoirs of one of Abu Dhabi's giant offshore assets (Field AD), and for the first time, full well plugging with Asphaltene is experienced in the field. While successful curative clean up treatments...

Also presented are the development methods and chemical synthesis details for the development of a squeezable product. A novel fast screening technique is detailed as well as a new type of residual monitoring method...

...Introduction Abstract Objectives/Scope The Pabdeh Group of Tertiary Paleocene to Oligocene age was deposited in a foredeep basin created by an obducted compressional thrust front that extends from Northwestern Oman into the Northern Emirates. The unit is represented by marls interbedded...

... to the depositional processes which generated the geometries and distribution of facies. Based on well correlations within the study area, the Bab shale is roughly 100ft near the Shuaiba platform. It forms a wedge on the slope of the platform and gradually thins out to ~17ft towards the north. The deposition...

...-porous baffles indicate high heterogeneity caused by rapid changes in deposition. Current exploration and drilling proposal are precluded due to the ambiguous understanding on reservoir anisotropy and dim-identification from seismic due to the thin reservoir thickness. To mitigate the challenge from...

The reservoir of interest consists of a thick organic and clay-rich dense zone at its base characterised by mud-supported, discoidal orbitolinid-rich deposits. This interpreted mid-ramp dense succession...

... attributes to extract sedimentary facies maps by combining lithofacies and logging facies. Based on the above analysis results, a sedimentary model has been summarized. According to this study, the target strata are mainly carbonate deposits of gentle slope with shoal, inner shoal and grain flat facies...

... and changes in fluid properties and conditions that warrant mitigation by chemicals. The plan was to inject corrosion inhibitor at the start of the pilot and switch to a corrosion/asphaltene combo chemical with CO 2 break-through, as it tends to destabilize asphaltene and lead to deposition. Once water cut...

... and were calibrated with well data. The Mishrif Formation was deposited during Late Cretaceous Cenomanian time. In the study area it has a gross thickness ranging from 532 to 1,269 ft as derived from the drilled wells; the thickness rapidly decreases eastward toward the shelf edge and approaching...

... Abstract The study area covers 1,300 km2 in southeastern Abu Dhabi and focuses on the Aptian (Apt.) 5 Upper Shuaiba progradational clinoform system. The Shuaiba Formation has been well-studied at the regional level, but with comparatively less focus on the Apt. 5 system. Studying depositional...

Analogues are found in Upper Austria some 250 km to the West, where several large gas fields in Lower Miocene deposits located in front of the advancing Alpine wedge have been discovered by another operator. In that area the fans are only partly involved in the fold-thrust...

... Abstract Sludge formation could significantly impair well productivity if deposited in the wellbore or surface flow lines. In a field where sludge formation is not common, an oil production well showed a sudden deterioration in well productivity. Thorough investigation of abnormal well...
