PATENT

Despite the young age of Hossein Ameri, he patented an invention. This inventor patented a foamed cement for oil and gas cementing operations. He is a petroleum engineer has enough knowledge about drilling operation and by conducting several tests in National Iranian Drilling Company (NIDC)'s Cement Designing Laboratory has reached this goal. He made vast research on drilling cements and developed his idea under the supervision of Engineer Hadi Tabandehjou as NIDC’s Engineering and Well Cement Planning Department Manager (haditabandeh@yahoo.com). After more than one year of experimental challenges and tests, he reached to a formulation of a drilling foamed cement with particular characteristics that although its low price by specified making procedure, it has several advantages than other conventional lightweight cements in the oil industry globally. 

THE PATENT CHARACTERISTICS

  • It has a low Density (75 pcf) that can be reduced to near 45 pcf. (lower than distilled water density!!!)
  • Its Compressive Strength in the comparison of other lightweight cements such as bentonitic cement that has less than 1000 psi compressive strength,  is more than 1300 psi and can be increased by other additives.
  • The Thickening Time of this cement is more than 3 hours and it is appropriate for the common cementing jobs. Also, the thickening time could be increased by a brief change in the mixing procedure for deep wells cementing operations.
  • On the contrary of conventional cements, the Rheology of this cement becomes better at high pressure - high temperature (HPHT) condition.
  • The Settling, Free Water and Fluid Loss of this cement are ZERO!!!
  • Despite its very high Porosity (near 75% !), it has very low Permeability (near 0.011 mili-Darcy !) and it is very appropriate for zonal isolation operation as a formation barrier material.
All of these results and features have been proved by standards of API and ISO tests in NIDC's industrial laboratory, different microscopic photography and various computed tomography scans analysis and their image processing and 2D and 3D volume rendering.
