Alkaline Polymer Flood for a Southeastern Alberta Oil Field – 1984 (Amoco)

This is a medium gravity (24⁰API) sandstone reservoir where the waterflood recovery was relatively low. Full diameter radial corefloods showed that a considerable oil could be swept by adding polymer and alkaline to the injected water. First a waterflood history match was obtained and then some forecasting production scenarios were run using a chemical simulator that was developed jointly with a consulting company. After one year of injecting alkaline and polymer a declining waterflood production trend was reversed. After about six years from the time of start of the chemical injection the incremental oil recovery above waterfllood was 8% of OOIP.

Screening of All Amoco Reservoirs For EOR Potential

After Amoco acquired Dome Petroleum in the late 80's it became apparent that a proper inventory of company reservoirs was needed. A detailed database was created showing geographic location, reservoir rock parameters, fluid properties and column indicating the EOR method most suitable for each reservoir that the company had sizeable interest. The most promising candidates were further studied by means of model simulators and laboratory radial core and slim tube testing. The reservoir candidates that passed the company economic hurdle were selected for field pilot or full scale applications.

Five Layer Modeling of a Retrograde Condensate Gas Reservoir

The reservoir is a large carbonate reservoir in a very good communication with a large aquifer. The reservoir was produced by cycling the residue gas and some pressure depletion. The reservoir simulation involved history matching dry gas cut and water/gas rations for all wells in the reservoir and then forecasting the performance of alternative depletion strategies. Forecasting was complicated by the need to incorporate an approximation of the gathering system, the processing plant, artificial lift (gas) and automatic conversion of injectors. The reservoir had 124 wells and 20 years history. The challenge was to develop a cost effective, representative model of the reservoir. The model was used as an operational tool.

Test Driving a Large Diameter Still Pipe In Hard Permafrost (Amoco)

When frozen, soils become very hard. This was of concern, regarding the installation of offshore production platforms, to the company that was spending $400 million per year exploring for oil and gas in the Canadian Arctic. After the site was continuously cored to 400 feet depth the 20 inch steel pipe was test driven by utilizing the pile drivers from conventional impact hammers to high frequency "sonic" drivers. This test project demonstrated that only the "sonic" pile drivers can drive the large diameter (500 mm) steel piles in hard frozen (-7 C) ground. The rate of penetration was 30 feet (10 m) per hour.

Tarsuit Man-Made Exploraton Island, Beaufort Sea, 1982 (Amoco)

Beaufort Sea is covered with multiyear ice for about eight moths of the year. This condition restricted the use of floating drilling ships for about four months of the year only. For this reason the company decided to construct the man-made exploration islands in water depth from 82 feet (25 m) to 165 feet (50 m). In these water depths the ice moves continuisly up to several mile per day. The island constructed from granular material dredged from the seabed by applying the hydraulic cutterhead and hopper dredging operations. To be able to construct these large (5 million m³) earth structures in the water, first the granular materials had to be located by employing the shallow seismic and coring tools. In 1982 the first island in water depth more than 20 m was completed. The island was designed and constructed to withstand the ice loads during the winter and sea waves during the summer. The performance of the island exceeded expectations and we were able to drill two wells from the Tarsuit island instead of planned one.

SSDC/SSDC II Bottom Founded Mobile Offshore Drilling Unit, 1982 - 1986

Building submerged berms and caissons takes time. Caisson Islands are the most efficient method for exploration drilling systems in deeper ice covered water, but it also needs to be mobile to be cost efficient. The SSDC concept which used a VLCC as the foundation of a steel drilling caisson. The need for a submerged berm still required the use of dredges and support vessels for construction however. The addition of the SSDC II (the steel MAT) made for a truly mobile drilling unit with the ability to operate in a large range of water depths.

No other drilling platform has matched the success of the SSDC/SSDC II in drilling operation in the Beaufort Sea. The combined unit was towed onto location in the summer and easily set down on location every time without problem. The wells drilled with the SSDC/SSDC II were always problem free without complication. The entire operation of the SSDC ran very smoothly and worked successfully throughout the winter for a number of drilling seasons in the Beaufort Sea, conclusively demonstrating the feasibility of year round oilfield operations in the Arctic.

The SSDC/SSDC II was a breakthrough in the development of Beaufort Sea technology - a giant leap. A third generation bottom founded unit, the CHAMP, was designed under the project management control of several of CANZEN's principals. The CHAMP uses the lessons learned with the SSDC to extend both the water depth capability and drilling/early production capabilities of the SSDC.
