Packer

1 Packer adalah penyekat untuk completion/WO Dibagi 2 : 1)1. Packer adalah penyekat untuk completion/WO. Dibagi 2 : 1) Production Packer. 2) Treating/testing Packer

2. Pemisahan ruang di well tujuannya :1. Melindungi casing dr P tinggi baik dari well atau injeksi

dan fluida penyebab karat2. Isolasi thd bocor yg ada di casing, perforasi yg di

squezed atau interval produksi yg lebih dari Satu3. Menghilangkan efek heading & surging gas krn adanya

gas yg terakumulasi di annulus4. Penggunaan untuk peralatan artificial lift4. Penggunaan untuk peralatan artificial lift5. Akan dipasang safety valve6. Menahan packer fluid di annulus

3. Jenis PackerUmumnya dari karet dipadatkan u/ penyekat dg slip, i fl t bl k t k d k b ( li h dinflatable packer, cement packer, dan packer bore(polished bore) receptacle atau PBRS

1. permanent packer : u/ permanent completion, dimanapacker adalah bagian dr casing, tubing dipisahkanruangnya & dpt diangkatg y p g

2. retrievable packer : adalah bagian dr tubing & tubing tdk dpat dilepas dg packernya. Tubing akan melekat kecasing selama packer belum lepas

Bagian-bagian dari Packer

bagian2 Packerbagian2 Packer1. Seal element : yg menyekat anulus tubing/casing.

Dibuat dr elastomer atau asbestos yg dpt ditekan untukberubah bentuk waktu packer dipaki u/ mengisi ruangantara mandrel dg dinding casing

2. Packer mandrel : badan utama packer yg terdiri drmetal u/ jadi pegangan seluru komponen packer

3. Slips : Komponen mekanis packer dg bentuk gigigerigi yg menyentuh ID casing & mencegah gerakanPackerPacker

4. Cone : silinder tersusun (tappered) tempat masuknyaslip untuk menekan gerigi pd dinding casing

5. J slot: permukaan bergerigi berbentuk J ygmengontrol gerakan slip relatif thd cone

6 H d li H ld D B tt l t h d li t6. Hydraulic Hold Down Button : alat hydraulistpencegah gerakan umtuk memegang mandrel ditempatnya saat slip mulai kerja & memberi kekuatanpenahan tambahan

7. Backup Ring : per metal yg bisa mengembang diatasp g p yg g gdan/atau dibawah seal element yg dipakai u/ menahanpengembangan seal secr berlebihan

Safety Systems

A Typical BOT Flow Control Device

Sliding Sleeves- controls flow between workstring and annulusP fil Ni l ll t l t b l d i th Profile Nipples- allows tools to be placed in the string by pumping or wireline

Blanking Plugs/Chokes- isolates or controls fluid flow up workstring

Accessories Running toolsRunning tools Retrieving tools Shifting tools

Sliding Sleeve Applications

Plug the tubingI l t Isolate zones

Check flow in either direction Choke the flow in either Choke the flow in either

direction Selectively communicate

between the tubing and the annulus

A Typical Subsurface Safety Valve

Subsurface Safety systems are installed in the wellbore as part of the completion.

Typically they are installed in the completion tubing string a few hundred feet below the seafloor in offshore applications. If the production platform were damaged or destroyed, the well would be shut in below the seafloor, preventing loss of the well and pollution of the environment.

Controlled by surface hydraulic pressure, preset flow differential, pressure drop.

Well Requirements Evolution

Technology Progression

Single Zone Completion

Common simple completion

Single zone of interest isolated

Production of oil and gas through theProduction of oil and gas through the completion

Technology Progression

Multiple Zone / Commingled ProductionAllows the operator to produce fromAllows the operator to produce from more than one zone at the same timeA cost effective method of completionp

Technology Progression

Dual Zone CompletionfProduction from more than one

zone in the wellbore

M li t d l tiMore complicated completion requirements

Horizontal Completion

Production from a Horizontal Production from a Horizontal Wellbore

Greater Exposure to the Producing Formation

Reduces the number of wells requiredrequired

Multilateral Completion
