When drained volumes want to be increased or to reduce investments with additional drilling wells, we can use horizontal wells as a good alternative for optimum exploitation of the oilfields. This is supported because the horizontal wells productivity becomes higher than in a vertical, due to that they communicate a large area of the producing formation, cross natural fractures, reduce pressure drops and advances of water-oil or gas-oil contacts are delayed.

In Mexico, several horizontal wells have been drilled in different kinds of formations, which initially have responded with production expectantions. However, after a short production time, productivity conditions have been reduced significatively, which have practically condemned the use of this technology in the development of hydrocarbons exploitation.

Therefore, in this work a comparative evaluation of the initial productivity of horizontal wells with respect to vertical wells is made to know their behavior and to identify design parameters that govern the feasibility of obtaining successful horizontal wells.

Analysis of horizontal wells on Agua Fria, Cantarell and Abkatun fields (North, Northeast Marine and Southwest Marine Regions, respectively) are included in this study.
