Investigation of Cementing Failures in Deepwater Brunei

Well No.2 is a well at Block CA-2 deepwater Brunei where it is located in the east of Block CA-1 and west of Block SKE (Malaysia) and is about 100 km from Brunei shore. The sediments in Block CA-2 have thicker, young sediments which ranging in age, mainly derived from late Miocene to present Bara...
