PERFORMANCE OF DIFFERENT ACIDS WITH VARIOUS FORMULATIONS FOR SANDSTONE FORMATION (PANGKOR SAND)

This project is about the performance of different acids with various formulations for sandstone formation. The objective of this project is to find the most suitable acid formulation for sandstone formation. Sands from Pangkor Island are used as sample for experiment.
Matrix acidizing is done to remove damage near wellbore area by dissolving unwanted or blocking material inside the pore. This operation can be very beneficial if proper planning and appropriate acid formulation is used.

To find the most suitable acid for sandstone formation experimental work must be done. After obtain sample from Pangkor Island, the sand grains are converted into sand compacted core to measure porosity and permeability before and after acid treatment is made. The change in porosity and permeability will be tabulated then the result will be observe and analyze. Trial and error method will be used to gain the most suitable acid formulation for sandstone.
