TAM INTERNATIONAL TECHNICAL BULLETINSlikPak P&A Application in GOMTAM Houston deployed a Slik-Pak carry fluid system onslickline off an ROV subseamultifunctional vessel recentlyin the Gulf of Mexico. The objectivewas to run through aBOP that required repair. TheBOP stack has a minimum IDof 2.99.” Glenn Thomas, ServiceSpecialist, ran the jobwith assistance from AlexOsorio, Technical Advisor.The bridge plug was used as asecondary isolation plug duringthe removal and repair ofthe BOP stack.The packer was set in4,347 feet of water in a remotesubsea well. During the release,the Pull Intensifier wasactivated and stroked 9 timesbefore releasing from thebridge plug. Since there weredifficulties when releasing, andit was a P&A job, the customer,Mariner Energy, decidedto leave the packer inthe hole.Photo below left: The SlikPakassembly is lifted into position.Photo below: The SlikPak isguided into the BOP stack.TAM International www.tamintl.com 2

TAM INTERNATIONAL TECHNICAL BULLETINTAMCAP Testing: 13-3/8”By Bob BrooksTotal in Indonesia recentlystarted running and setting the13-TC-01 TAMCAP packersinside 24” conductor pipe ontheir offshore wells. In a numberof cases gas migrationwas seen to come to surfacepast the packers after about 3to 4 weeks after the packerswere inflated. In order to betterunderstand the issue, andto answer the Incident Reports,we set up a test here toinflate a 13-TC-01 inside asection of 24” conductor pipe,inflate the packer to the sameinflation pressure as was usedin the field and apply 150 psigas pressure under thepacker, and look for any leakage.The test fixture, asshown in the photo, was usedand after the packer was setthe area above the packerwas filled with water so thatany gas leakage could be observed.The inflation and gaspressures were monitoredelectronically so that anychanges could be noted. Thepacker was initially inflated to950 psi, and then the 150 psigas pressure was applied underit. The testing lasted for 4weeks, during which pressurefluctuations in the elementwere noted as the temperaturevaried. There was no gasleakage, or gas pressure deterioration,detected during thistime. This proved that if thepacker was fully inflated at theclosing pressure that low pressuregas migration is stoppedby the packer.In order to try and determinewhy gas migration past thepacker was seen, the inflationpressure in the packer wasreduced to see at what inflationpressure we started toleak past the packer. Whenthe inflation pressure was reducedto around 150/200 psiwe saw evidence that the gaswas leaking past the packer.This would indicate that if wehad a “soft-set” of the packerthat gas migration could happen.In the photo below, notethe deflated packer with thepermanent deformation of theslats from inflating the packerin the conductor pipe. Therewas no evidence of the rubbercover being torn/damaged atthe end rings, which couldhave allowed gas leakage.The equalization port in theend sleeve at the bottom endof the packer was weldedDeflated packer after testing.closed to eliminate any gasbypassing between the bladderand the cover.Test fixture for 13-3/8”TAMCAP.TAM International www.tamintl.com 3
