Recently deep water technology has been widely known as one of promising field in oil and gas business in offshore region. As I share and talk with colleague and friends, subsea technology is one of the options to be applied in deep water sector. An exploration of oil and gas is increased along with the demand of the use of this non-renewable energy in the future. Even though currently I have not yet directly involved in the subsea industry, I hope someday I can be the specialist in this area.
When I was in my master study in Norway, I had a chance to attend a class that can describe this subsea world in a brief and comprehensive explanation, called Subsea Technology class. It is a good and recommended class to be followed since the subject is very interesting and new (for me). During the class we have an opportunity to write a paperwork explaining any subsea field in anywhere. It should be something unique and have a special configuration or items included in the subsea system. I, with my colleague, decided to write our project about a subsea field in Indonesia, a small one, located in north region of Indonesia. Detail of introduction can be seen at the bottom.
In the class we also have a chance to subscribe to a very cool, yet very informative website about subsea technology, in subsea1.com This link is a great website describing all subsea equipment and its function in a detail description and with a great image, also cool video. Since I have been graduated, I can not access it anymore but you can try to subscribe it (but you have to pay much more than when I was in my master :d).
Here a snap shot from subsea1.com (click the picture)
To summarize, this website will tell you lot of information about each of equipment, instrument, and tools in every system above. There are also some videos regarding the subsea tools installation when it is being placed in the field.
Introduction, Kepiting Field – Indonesia
The Kepiting Field is a small oil field, owned by Conocophillips Indonesia, comprises of 2 wells located in Natuna Sea, Indonesia at distance of approximately 1000 km of Jakarta. This marginal field has been profitably active for oil and gas production from October 1986 to August 1989. The water depth is 90 m with relatively mild environmental condition and is out of the trails of Southern China Sea’s typhoon such that it is generally calm all over the year. Maximum 100-year storm wave height (hmax) is 12 m and the significant wave height (hs) is 5.8 m. During December and January the weather is most severe, at when the 4.6 m wave height and 56 km/h wind may occur and can last up to 10 days. The Kepiting Field has a limited production capacity of 4500 BPD of oil per well. This limitation is intended to avoid excessive fines production of the reservoir. The hydrocarbon is characterized as waxy crude oil (35% wax contained) and has pour point of 100o F (38o C). With specific gravity of 39o API (0.83 g/cm3), it is considered as sweet crude oil.
