We are planning for horizontal stand alone screen water injection wells, where a Calcium Carbonate filter cake breaker will be used to enable injection services . The breaker is designed to be slow release to allow placement of fluids across horizontal section.
As a contingency measures, Several type of Fluid Loss Control Pills are being tested.
One of the FLC pills is Sized Salt (NaCl) screen bridging pill, which can be removed by the introduction of under saturated brine solution or during injection service.
My question is:
Given that the Calcium Carbonate Drilling Fluid is understaturated and the Sized Slat Pill has to be in a saturated brine solution, could a Sized Slat Screen bridging pill be used with a Calcium Carbonate Drilling Fluid system?
Any experience/advice most appreciated.
