A 60-ft thick sandstone formation with porosity of 0.2 contains 20% in volume of CaCO 3 in a 16 radius around an 8 diameter wellbore.
- A 60-ft thick sandstone formation with porosity of 0.2 contains 20% in volume of CaCO3 in a 16" radius around an 8" diameter wellbore. This CaCO3 is to be completely removed by a 10% HCl solution during an acid stimulation. The specific gravity of 10% HCl solution is 1.07. Answer the following questions based on your calculations:
- What is the gravimetry dissolving power of the HCl solution?
- What is the volumetric dissolving power of the HCl solution?
- What is the minimum volume of the HCl solution required to dissolve all the CaCO3 in this60-ft thick sandstone formation?
- What is the volume of the HCl solution required to fill the pore space in the region of CaCO3 dissolution for the60-ft thick sandstone formation?
- What is the total theoretical HCl solution volume required in the treatment of60-ft thick sandstone formation?
