1966 - Zama, Keg River Formation discovery, 255 known pools 1967 - Virgo, Keg River Formation discovery, 165 known pools 1969 - Shekilie, Keg River Formation discovery, 94 known pools 1975 - Zama Plant First Phases started construction February 2000 - TransCanada shelves plans to build a $69-million pipeline extension from Zama to the Fort Liard gas fields. August 3, 2000 - TransCanada - The Zama sour gas processing plants and associated 205 kilometre gathering system. The gas plants sweeten gas and remove natural gas liquids such as propane and butane as well as hydrogen sulfide and other impurities. The Zama II plant has a design of 50 MMcf/d. The Zama III plant has a design capacity of 65 MMcf/d. Enbridge Pipeline - extends approximately 870 kilometres (540 miles) between Norman Wells, Northwest Territories and Zama Alberta. From Zama, crude oil is transported through the pipeline facilities of others to Edmonton for refining. As of July 2001, 26,000 barrels of sweet crude are shipped every day to Zama from Norman Wells along the Enbridge-owned pipeline which was completed in 1985. Because of the permafrost, it has to be cooled down to ensure that it does not melt the frozen earth and cause pipeline breaks. March 2001 - Ventus Energy Ltd. - During the 1st quarter of 2001, Venus drilled 19 Keg River oil wells in the Sousa area resulting in 17 oil wells for a success rate of 84%. A major facility expansion in Sousa will be complete in June allowing full production. April 11, 2001 - Petro-Canada - A leak was spotted by air on a 33-year old PetroCan Well in Shekilie. Mainly salt-water with minimal liquid gas residue has pooled in an area 600 metres by 100 metres. Very low-levels of H2S was being released into the atmosphere but not enough to pose a risk. According to AEUB the exploratory well was drilled in 1968, but production was suspended in 1995 and the well was capped. June 13, 2001 - Barrington Blow-Out - Late afternoon a plume or undetermined origin was spotted by an Alberta Forestry tower and was found to be a blowout at 5-31-116-10w6. The original well was drilled in 1983, then suspended in 1984. It is located approximately 50 kms west of Zama City. Crews must be flown in by helicopter, as no summer access exists. June 14, 2001 - Barrington Blow-Out Update - Well control specialists are on site. The well is continuing to flow dry gas, and has not been ignited. Air monitoring is in progress to measure any threat from escaping gas. June 22, 2001 - Barrington Blow-Out Update - The sour gas (estimated at approximately 36% hydrogen sulfide (H2S) content) was ignited today, after unfavourable wind conditions had affected well-control efforts for several days. The gas was flowing at a rate of 7.8 million cubic feet per day. At 8:00 am this morning the well was ignited, to allow crews easier access to the well. July 12, 2001 - Barrington Blow-Out Contained/Update - the well has been controlled and a relief well drilling program will be submitted to the AEUB. July 20, 2001 - Sour Gas Well to be Abandoned this Winter - Barrington Petroleum receives approval from AEUB for well abandonment program. The well-control company that was initially hired to complete ‘well-killing' procedures stated that the tubing in the well parted at 97 meters and believes all other tubulars are parted or damaged at that level.

October 1997 - Phillips Petroleum Aquires Zama Field for $165 million (US) from Gulf Canada Resources - Phillips increased its net reserves by 80 million BOE with the acquisition of 100 million BOE in the Zama area. Average net production from the Zama area in 1998 was 5,550 barrels per day of oil and natural gas liquids and 60 MMcf/D of gas. In 1999, gas production is expected to be 95 MMcf/d, an increase of more than 50% over 1998 levels. The exploration and development program continued through the 1999-2000 winter season with the drilling of 13 wells. Two new discoveries were made in the Amigo area. Oil and Gas production continued with recompletion of 30 natural gas zones in existing wells, developing 20 MMcf/d of gas production through the first half of 2000. December 2000 - Apache Corporation announces acquisition of Zama field from Phillips Petroleum for approximately $490 million (US) - Along with 500,000 acres of land, Zama also features three gas plants, 240 kilometers of gas gathering pipelines, seven crude oil processing plants and extensive seismic coverage. Current production is approximately 70 million cubic feet (MMcf) of gas and 6,000 barrels of liquid hydrocarbons per day.
