HOW TO CHOOSE THE CENTRALIZER We would like to share with you why we’ve run  centralizers . How can you choose centralizer ? You might ask yourself : why do we use a centralizer to keep the casing centered in the hole or parent casing. So that cement can flow over the entire annulus when your semen is set in the right places. You can achieve an effective semen sheath that promotes well bore integrity. FIVE DIFFERENT CENTRALIZERS Here you see a sample of five  different centralizer  designs. FIVE-DIFFERENT-CENTRALIZERS All these for five and a half inch casing to be running eight and a half inch open hole. They represent two families both spring centralizers and rigid centralizers. Let’s go through some of the  differences centralizers   with the bow spring design.Like these two are very common . 1) They have welded and non welded bow Springs .when these bows push against the wellbore, they push back to help center the pipe important considerations 2) When selecting a bow s

Float Shoe and Collar PRODUCT INTRODUCTION Float Shoe  is a rounded profile component attached to the downhole end of a casing string. contain a back pressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing. Float Collar  is a special coupling device are placed one to three joints above the guide shoe or float shoe that contains a check valve to permit fluid to pass downward but not upward through the casing.They provide a seat for the cement plugs, the bottom plug pumped ahead of the cement and the top plug behind the full volume of slurry. Once seated, the top plug shuts off fluid flow and prevents over-displacement of the cement. Our Float Shoes and Collars are manufactured to API standards and are tested to API-III C. The float shoes and collars have been designed and manufactured to withstand the high temper
