STATUS OF OIL SANDS PROJECTS (Underline denotes changes since June 1994)<br />

COMMERCIAL PROJECTS (Continued)<br />

The expansion, at a cost of $200 million, required the drilling of an additional 213 wells for steam injection and bitumen<br />

production, plus an expanded distribution and gathering system. Wells for the expansion were drilled directionally from eight<br />

pads. The commercial project includes an expanded main complex to include facilities for separating water, gas, and bitumen;<br />

a utility plant for generating steam; and office structures. Additional off-site facilities were added. No upgrader is planned for<br />

the expansion; all bitumen extracted is diluted and marketed as a blended heavy oil. The diluted bitumen is transported by<br />

pipeline to the northern tier refineries in the United States and the Canadian west coast for asphalt production.<br />

An application to the Energy Resources Conservation Board received approval in early November 1984. Drilling began in<br />

February 1985. Construction began June 1985. The expansion was on stream October 1986.<br />

In 1989 production was increased to the design capacity of 1,600 cubic meters of oil per day. The Peace River complex com<br />

pleted its first full year of operating at capacity in 1990. Its 10 millionth barrel of bitumen was produced in March. Through a<br />

combination of increased bitumen production and reduced energy requirements, the unit bitumen production cost has been<br />

reduced to 30 percent of that averaged during the first full year of operation. The operation was producing about<br />

10.000 barrels/day of bitumen. However, in 1994 production declined to 7.000 barrels/day. Changes to the recovery process to<br />

restore production were implemented late 1994 and results to date have been encouraging. Ultimate recovery is projected at<br />

55 percent of the bitumen in place.<br />

On January 25, 1988 the ERCB approved Shell Canada's application to expand the Peace River project from 10,000 barrels per<br />

day to approximately 50,000 barrels per day. PREP II, as it will be called, entails the construction of a stand-alone processing<br />

plant, located about 4 km south of PREP I. PREP II would be developed in four annual construction stages, each capable of<br />

producing 1,600 cubic meters per day. However, due to low world oil prices and continual with uncertainty along the lack of<br />

improved fiscal terms the expansion project has been postponed indefinitely. Some preparatory site work was completed in<br />

1988 consisting of the main access road and drilling pads for PREP II. The ERCB approval for PREP II was allowed to lapse,<br />

however, in December 1990. Continued world oil price contributed uncertainty largely to the decision not to seek an expan<br />

sion.<br />

Research into the application of a steam drainage process has led to the design of a two-well horizontal well demonstration<br />

project. The project is testing the technical and economic feasibility of bitumen recovery utilizing surface-accessed horizontal<br />

wells, employing an enhanced steam assisted gravity drainage process. The estimated lifetime of the project is 12 years during<br />

which 80% of the bitumen initially in place is thought to be recoverable. The project is tied into existing Peace River complex<br />

facilities and began operating in November 1993. After steam injection for two months, production was expected to be about<br />

1,000 barrels per day.<br />

Project Cost: $200 million for PREP I<br />

$570 million for PREP II<br />

- PRIMROSE LAKE COMMERCIAL PROJECT Amoco Canada Petroleum Company and Alberta Energy Company (T-170)<br />

Amoco (formerly Dome) proposed a 25,000 barrels per day commercial project in the Primrose area of northeastern Alberta.<br />

extensive explora<br />

Amoco is earning a working interest in certain oil sands leases from Alberta Energy Company. Following<br />

tion, the company undertook a cyclic steam pilot project in the area, which commenced production in November 1983. and<br />

thereby earned an interest in eight sections of adjoining oil sands leases. The 41 well pilot was producing 2,000 barrels per day<br />

of 10 degrees API oil in 1984.<br />

The agreement with Alberta Energy allows Amoco to earn an interest in an additional 194,280 acres of adjoining oil sands<br />

lands through development of a commercial production project. The project is estimated to carry a capital cost of at least<br />

$C1.2 billion and annual operating cost of $C140 million. Total production over a 30 year period will be 190 million barrels of<br />

oil or 18.6 percent of the oil originally in place in the project area. Each section will contain four 26-well slant-hole drilling<br />

clusters. Each set of wells will produce from 160 acres on six acre spacing. The project received Alberta Energy Resources<br />

Conservation Board approval on February 4, 1986. A subsequent amendment to the original scheme was approved on August<br />

18, 1988. The 12,800 acre project will be developed in three phases. Four 6,500 barrel per day modules will be used to meet<br />

the 25,000 barrel per day target.<br />

In 1989, Amoco undertook some additional work at the site by drilling a horizontal well. In 1990 Amoco announced it would<br />

drill two more wells to assist in engineering design work. Six hundred thousand dollars was planned to be spent on this effort<br />

in 1990.<br />

A new steam injection heavy oil pilot was placed in production in early 1991. By the end of 1991, AEC expected to be testing<br />

more than 80 wells various using techniques, including a cold technique which employs specialized pumps.<br />

In 1991, ERCB gave approval for seven horizontal wells to maximize bitumen recovery under a steam stimulation/gravity<br />

drainage process.<br />
