Marrat Jurassic reservoir in Umm Gudair Field, West Kuwait is characterized as deep and tight carbonate limestone reservoir. Most vertical wells are low producers due to poor reservoir properties in addition to the reservoir pressure depletion. In order to enhance Middle Marrat reservoir productivity, the practice of horizontal drilling is being adopted. However, boundary navigation and optimizing the drainhole within the desired target layer poses the biggest challenge in this regard.
