Sand production potential<br />
• No sand production detected during the first year<br />
• Currently 4 wells are producing moderate amount of sand<br />
• Sand production triggers<br />
− water breakthrough always beings more sand<br />
− reservoir pressure depletion 150-400 bar<br />
• The sand rate limits maximum erosion-free fluid velocity in pipelines 20-30 m/s<br />
• <strong>Kristin</strong> solution for sand protection<br />
− 4 wells completed with 0.35mm screens (slotted liners)<br />
− 8 wells completed with liner and perforated with vertically orientated shots<br />
