Horizontal Drilling

Horizontal drilling is actually born in June 1980 with the drilling of the Elf Aquitaine-90 Lacq in southern France.
 It is likely that some horizontal wells had been drilled before that date, among others in Russia, deliberately or not, but without real success or development to 80s Lacq-90 was followed by 91-Lacq, France can still Casteralou Rospomare-6d Pelican lake in Italy and Canada.



  In the late 80 hundreds and then thousands of horizontal wells were drilled each year.
      
In our country it was in 1992 that took place on the first horizontal drilling. This first horizontal well was performed at Hassi R'Mel for the operation of the oil ring with a throughput of two to three times higher than the neighboring vertical wells.
      
   Such success can only be explained by the excellent results obtained through the technique of horizontal drilling, despite some failures, especially at first. This success was made possible by rapid technological evolution of equipment, namely:

 development of real-time measurement tools;

 development of a new generation of downhole motors;

 evolution drilling fluids and development of new solid control equipment;

 understanding of the drillstring behavior.
