Abstract

The purpose of this research is to use effective method of drilling to improve the recovery process of hydrocarbons in oil and gas sector. Hydrocarbons are present in large amount beneath the earth. By using exploration geo physics, the reservoir of hydrocarbons below the earth can be located with more precision and accuracy. The first step consists of the geological and the seismic survey to obtain the image of the beneath rocks. In the next, step drilling is performed to reach the desired depth. Depending on the types of rocks beneath the earth the drilling performed may be directional, vertical or horizontal. This paper will focus on “how multilateral/horizontal drilling can improve the recovery of low permeable hydrocarbons”. Now a day’s offshore drilling is also performed.

Key words:  Hydrocarbons, seismic survey, multilateral drilling, offshore drilling.
