MS Spacer

Filtrates from cement slurries can damage producing formations, adversely affect production, and require unscheduled stimulation treatments to address the problem. In addition, the increased equivalent circulating density (ECD) generated by pumping cement slurries can lead to induced losses and contribute to poor quality cement job.

The Riteks MS Spacer system is used to help mitigate lost circulation issues while cementing. It can minimize filtrate invasion and damage, and induced losses. Based on it ultralow invasion fluid technology, this system forms a barrier at the wellbore wall to strengthen the wellbore. The formation can retain its integrity and permeability for optimized production because of the near 100% return permeability property of the spacer.

MS Spacer reduces slurry fallback after placement, which prevents induced losses and eliminates costly remedial cement jobs. In wells with critical fracture gradients, Riteks MS Spacer technology enables the use of standard slurry designs and densities where highly extended or special lightweight slurries were previously required. This eliminates the need to compromise on thickening times and compressive strength.

MS Spacer as a free-flowing powder can be dry-blended before it is transported to the job site and can be easily dissolved in the mixing water.
