Our customers have found that our fluid calipers save money in cement, eliminate the need for wireline calipers and also save rig time.  Our Fluid Calipers pay for themselves and save you money. 

What Is A Fluid Caliper?

A fluid caliper is a survey to pre-determine the volume requirements for any selective cementing job. We will give you accurate information, already computed into cubic feet, without lost rig time!

How Fluid Calipers Work

We insert a colored marker in our flow meter and connect it to the vibrating hose at the discharge end of your mud pump. While you resume normal drilling, or circulate to condition the well bore before running casing, we perform our survey. Our highly accurate electronic totalizer gives us positive readings already converted into cubic feet.

how-we-do-itThe initial marker that is detected has been at the apex of the flow curve over the total annulus. It is necessary to correct for the area outside the flow curve over the total annulus. By using our correction factor charts, we can calculate with greater accuracy the actual volume required for your cementing purposes
