Success Story: Offshore Well Services Using Offshore Scaffolding Pipes Structure in TBA Field Salawati (Rigless)

Abstrak

Offshore TBA field production has going to the marginal phase where to produce need using artificial lift (gas lift). The gas source for the gas lift is the associate gas produced from the existing wells. The TBA field needs additional gas production to make up the Gas Compressor Unit due to production of the associate gas has declined. This additional gas production will be obtained from top layer of zone perforation. This perforation activity did not be able by using rig unit and snubbing units due to limited space deck on tripod platform and high cost operations.

To figure out the problem, offshore scaffolding pipes structure (Rigless) has become to be alternate option to complete the job. This alternate will be supporting as static lifting equipment to R/U all units and Running all devices at the platform during well service activities such as perforation, bottom hole pressure survey and gas lift valve replacement.

Success by using offshore scaffolding pipes structure (Rigless) with the steps procedure of installation and dismantle will be discussed in this paper. It is expected that the successful by using the offshore scaffolding for this operation activity is a new breakthrough how to make efficiency in the oil and gas industry.
