ABSTRACT:

After many years of production, the formation pressure and the oil reserves have dropped considerably while both water and gas production have increased. The remaining hydrocarbons in the fieldrequire technical studies that are more precise. Short radius well drill is a new approach at Hassi Messaoud. This method is applied to weak producers or dry holes which are redrilled horizontally or obliquely to improve hydrocarbon recovery. This presentation provides:

  • General resorvoir and horizontal well characteristics

  • The rational for drilling short radius wells

  • Technical methods for applying short radius at HMD

  • Review of the results

  • Conclusions and recommendations
