Bapco has successfully completed the drilling of 30 horizontal and deviated wells in the first half of 2009, it was announced. This brings to 64 the total number of non-vertical wells drilled in the Bahrain field using state-of-the-art directional, horizontal and re-entry technology.
The latest wells are part of a wider development drilling programme.
Directional wells are normally drilled anywhere from 0-75 degrees of vertical axis at pre-determined stages. Horizontal wells, on the other hand, are taken beyond directional limits and are landed to 90 degrees horizontally, whereby the wells will look like an 'L' letter. This exposes the same oil bearing formation as vertical wells, but at much higher intervals equal to the horizontal length.
