Abundant energy resources are available in East and South East Asia. Major energy producing countries in the region include China, Malaysia and former OPEC member Indonesia, while Myanmar may potentially join the producing group following the end of military rule and the opening of the nation's petroleum sector to more foreign investments. Brunei, China, Indonesia, Malaysia, Thailand and Vietnam have an estimated 31.4 billion barrels of proven oil reserves and 309.5 trillion cubic feet of proven natural gas reserves as of 2013.
Coiled tubing is a continuous length of flexible pipe wound on a spool that is straightened prior to pushing into a wellbore. There are a number of well intervention operations that can be achieved via coiled tubing, and it is sometimes used as production tubing in depleted gas wells. It is often more cost and time-effective than having to remove tubing from the well, as coiled tubing can be inserted into the tubing against the pressure of the well. Another advantage versus wirelining, is the ability to pump chemicals through the coil.
