GENERELT

utfØrt -Med enkel

kompletering andre produksjonstest ble utfØrt med dobbel

kompletering. Gas ble injisert fra overliggende gas sone.

Det ble brukt to "packers", og `side pocket mandrel` me(llom

disse. Som `flow controler` ble det brukt en `chemical

injection valve`. Den Øverste del-av denne ventilen er en

fj<�,rbelastet port som åpner for gas ved et bestemt minste-

trykk. Denne ble justert til et åpningstrykk på null for å

få minst mulig trykktap på gassen.

Ventilen består av to enheter:

- en choke-enhet for gass injeksjonen. Ventilen leveres

med `choke` stØrrelser på 3/16" og 5/16".

- en `check-valve` for å hindre retur av eventuell olje

med hØyt trykk gjennom "flow controler` og ut i

annulus.

Etter avsluttet produksjonstest av olje sone, setter en

plug i `S-1"-nipple, åpner 2 7/V XO SSD og 3�2` XA SSD for

produksjon kun fra `Micaceous sand zone`.

The lock-ng mechanism used is a spring-loaded ring that is designed to oock i pocket-locking recess of the mandrel. Latch can)e inst*d with a rninimum of force. When retrieving, a pins sheared, allowing the ring to move upward and perrfflttinghe valve to be pulled from the pocket.

Step 1 Step 2 Step 3 Step 4 OPERATING DESIGN PRINCIPLE

These drawings illustrate how simple it is to installa gas lift valve with Otis Tru-Guide equipment. Simi-lar steps are used to retrieve the valve from theside-pocket landing nipple.

Step 1 -After the kickover tool has moved throughthe Tru-Guide Mandrei, it is reversed and movedback up through the mandret. The spring-loaded

B" alignment key on the kickover tool orientation as-IRANSFER

sembly (A) is designed to align the kickover tool and -GUIDE RAIL

hold it in the proper position to be activated.

C. Step 2 - Upward movement shears the first shearfing on the actuator assembly (13), permitting the

D� pivot arm (C) to move out and lock at right angles tothe carrier tray assembly (IJI) for positioning on thecenter line of the side-pocket landing nipple for set-ting or pulling the gas lift valve.

Step 3-Downward movement of the gas lift valve iscontrolled by the transfer guide rails for a straight lineinto or out of the landing nipple. A no-go on -thelocking mandrel locates the gas lift valve in the nip-ple. Continual downward movement releases lthelocking keys, locking the valve in the nipple. When SIDE-POCKET

Stiger trykket ved inntaket til Otis test separator,

åpner high-pressure-pilot automatisk til atmoferisk

trykk det fØrer til at kontroll ventilen åpner til

reservoaret fra flow head `flow-valve` og `master valve

vil da st-enge. (Di.sse ventilene må ha trykk for å

åpnes).

På `rig-floor" og ved separator kan en stenge manuelt.

SIKKERHETSYSTEM PÅ OTIS'SEPARATOR:

Det er etter Ønske'fra Shell instalert to sikkerhets-

ventiler av typen "Farris` på separatoren. Begge

ventilene skal åpne på 1460 psi. Det er incjen

"Rupture-disc` på separator fra sikkerhetsventilene

er det montert en 3" linje med uttak under platformen.

PROBLEMER MED OTIS S-1 PLUG

Ved nedkjØring av S-1 plug, for test av prod. string, ble

det påvist feil ved dybde-indikatoren i 110tis W/L winch".

Pluggen ble så satt i S-1 nippelen. Strengen skulle trykk--

testes til 3000 psi. En oppn4dde kun et trykk på 1500 psi.

Ved trekking av pluggen måtte en bruke en jar-kraft på 750 LBS.

Satte deretter S-1 plugen igjen. Uten å oppnå den forventede

trykk Økningen. Etter en tid steg trykket og en oppnådde

3000 psi. FØr denne trykktesten ble det kjØrt "Drift-run

En påviste da en del forurensing. Blant annet en del DOP.

Dette kan muligens være årsaken til problemene'med S-1

pluggen.

PROBLEMER MED FLOPETROLS SSTT

SSTT fra Flopetrol er utstyrt med injiserings-system for

Glykol.

Etter oppstart fikk en problemer med pumping av Glykol.

En antar at grunnen kan være forurensningi`linjen plugget

utaksventilen i SSTTr

e,tter at Glykol linjen har fått skade ved ned-kjØring.
