UBEP SangaSanga Tarakan, Field Tarakan is located in Tarakan island, North East Kalimantan.<br />
Tarakan field discovered by BPM (Batavia Petroleum Maatschappij) in 1905. Production from<br />
this field commenced in 1939 and has continued to present. Since handover from Pertamina &<br />
Tesoro Indonesia Petroleum Company cq PT. Medco E&P Kalimantan to be own operated by<br />
PT. Pertamina EP in October 15th, 2008, Oil production from this field has increased rapidly<br />
from average 300 BOPD to 600 BOPD in 2 months.<br />
Tarakan field divided into three structure, one of the major structure to contribute oil is<br />
Pamusian structure, about 60% of daily oil production rate from Tarakan field is came from<br />
Pamusian structure. Total well drilled since BPM to Tesoro in Pamusian is 1078 well, which is<br />
present only produced from 42 wells. Well construction is vertically with open hole perforation<br />
covered by sand screen and produced from shallow zone in depth interval from 55 meters to 460<br />
meters. All oil wells at Tarakan field are produced with Sucker Rod Pumping unit as<br />
conventional artificial lift. Pamusian structure located in the heart of Tarakan city which means<br />
near populous settlements.<br />
Optimization of oil wells production is very important to increase daily oil production<br />
rate in Tarakan field especially from Pamusian. Plan of development to improve oil recovery in<br />
this field consist of two major activity such as reactivation suspended wells and introducing new<br />
artificial lift method which is more eco-friendly in populous area.<br />
Selection artificial lift method to be applied in Pamusian is Electric Submergible Pump<br />
(known as ESP) based on consideration such as (1) limited capacity of oil lifting using existing<br />
Pump Jack unit (which maximum Stroke Length unit range only between 24 inch to 54 inch).<br />
Observation from sonolog showed high dynamic fluid level means that Pamusian oil wells have<br />
higher potential than present production , (2) Delivery time of Working Barrel and Plunger used<br />
in Conventional lifting takes 24 weeks, (3) Low efficiency of existing Working Barrel, Plunger<br />
and Sucker Rod used in conventional lifting and also lack of availability during term of handover<br />
from TAC Medco to Pertamina own operation (4) Acceleration program to boost oil production<br />
in Tarakan field. Since operating interval depth of Pamusian wells is shallow, special designed<br />
ESP have to be applied for becoming more techno-economic and profitable. This ESP is easily<br />
found in the market with short delivery time, (5) Reduce low and off due to sand problem that<br />
caused by discontinuity fluid flow from reservoir into wellbore in conventional lifting, (6) Power<br />
consumption less than conventional pumping unit compared in same lifting capacity, (7)<br />
Environmental aspects.<br />
Innovation steps must be carried out in converting electric submergible water pump<br />
became applicable as an oil pump. ESP convertion as an oil pump accomplish by changing some<br />
inside material parts (ex. Impeller and seal) for becoming more oil resistant. Due to deal with<br />
sub-surface and surface issued, ESP convertion also completed by choosen common phase
inverter available at domestic market and used as Variable Speed Drive (VSD) which solved<br />
both electrical and operational flexibility issued in Pamusian oil wells.<br />
Until now, three (3) ESP have been installed in Pamusian oil wells which has increased<br />
daily oil production rate into double in well depth 110 – 235 meters, and proven has more total<br />
system efficiency compared with Conventional pumping unit.
