Abstract

The paper analyses and evaluates the actual drilling work to find out the root cause of lost circulation problem during the process of drilling across the carbonate zones and poor cement bond quality in Dai Hung wells. Based on that, the authors propose solutions to cure the lost circulation during the drilling phase and improve the cement bond quality across the carbonate zones in Dai Hung field. The proposed solutions consist of completely treating lost circulation across the fractured carbonate zones by using acid soluble cement prior to running casing, installing swell packers, using multiple-stage cementing tool with inflatable packer, and using light weight cement. These solutions strengthen the isolation property for interbedded zones containing oil, gas and water in Dai Hung field, and reduce the time and cost of remedial cement squeezing works.
