Proactive DTB Geosteering Technique Deliver Excellent Result in Lower Burgan Thin Channel Sand Reservoir-North Kuwait

Drilling of development wells in the Burgan sands involves very thin and sinuous targets. These targets are the channel sand stringers and contain a substantial amount of hydrocarbons. Optimal well placement is required to drain them in a cost effective manner. Conventional well placement has met with limited success in stringers and thus resulted in low production figures. This led to the introduction of Schlumberger’s distance to boundary mapping tool in Kuwait which has proven consistently that a proactive well placement technology can be translated into maximum reservoir contact, minimum well-bore tortuosity and a facilitator for optimal production. Due to the uncertainty that is inherently present in the distribution of the channel sands, the prediction of the azimuth of channel meander can now be confidently solidified with new deep and directional electromagnetic measurements. By detecting the upper and lower conductive shale boundaries the wells can be steered in this very challenging environment of channel sands. This well was successfully drilled using the distance to boundary mapping tool and the production test resulted above 5700 BOPD which is almost 100% above the expected production rate. This paper has also been submitted for the forthcoming SPE, KOGS conference during October, 2013, in Kuwait.
