Abstract:
Generally, Formation Damage can be defined as any reduction in near well bore permeability which is the result of any material from drilling, completion, production, injection, attempted stimulation or any other well inter. Which in this study is a result of any material from drilling. This research predicts the cause of the damage using Instrumental and Laboratory Techniques to determine the source and the cause of the damage using (core analysis, X-ray diffraction (XRD), Scanning electron microscope (SEM), Thin Section Petrography (TSP), X-Ray CT Scanning (XRCT), Formation damage system) and prevent this damage from occurring by modifying the properties of the drilling fluid or by modifying the drilling conditions in general.
After all the test was done the problem associated to formation damage found to be that there is a martial coating quartz grains which was found to be mainly composed of Silica and Aluminum.
The treatment is carried out by forming a process fluid containing an aqueous fluid containing a source of hydrogen fluoride and an inhibitor of amorphous silica precipitation.
