ABSTRACT Petroleum industry activity in western Canada during 1984 rebounded strongly to near-record levels, with the third successive annual increase following the 1981 slump. The year was marked by increased development drilling -- especially in Saskatchewan, further emphasis on in situ heavy oil wells, and a continuation of government incentives. Total number of wells drilled increased by 30% to 8765. Exploratory drilling reversed a three-year decline by rising 45% to 2863 wells. Development drilling reached a record 5902 wells, up 23% over 1983 and 15% over the 1980 record. Exploratory success rate decreased from 62% to 60%, with 1089 oil discoveries and 637 gas discoveries. The development success rate remained at 89%, with 4010 oil completions and 1228 gas completions. Exploratory drilling rose sharply in every area except Manitoba, and development drilling increased in all areas. Average well depths rose marginally in every province but Manitoba. Land sale revenue continued to soar, increasing by 44% to $812 million3, but still below the 1980 peak of $1311 million. Alberta land sale revenue totalled $624 million, Saskatchewan $124 million, British Columbia $62 million and Manitoba $2.5 million. Average price per hectare declined in the two most active areas, Alberta and Saskatchewan, but increased in British Columbia and Manitoba. Alberta exploratory and development drilling reversed a three-year decline and totalled 61% of western Canadian activity. Most of the significant discoveries were made in Devonian carbonates in the Chigwell-Bashaw area, Slave and Kitty areas, Peerless Lake, Rainbow-Shekilie and Dizzy Creek - Steen River areas. A new Lower Cretaceous clastics pool was discovered at Manyberries. Further development and expansion of oil sands projects were announced by Shell Canada in the Peace River area, by Suncor at Fort McMurray and by Esso at Cold Lake. British Columbia activity was centered around last year's Mississippian oil discovery at Desan and another Mississippian gas find at Sikanni. Also, significant CO2 reserves were found by Shell in the Flathead area, just north of the Montana border, and interest increased in west coast offshore potential, despite a 12-year moratorium. Saskatchewan activity expanded sharply for both exploratory and development wells, and was concentrated on the Lower Cretaceous Viking play in the Kindersley-Kerrobert area, Lower Cretaceous heavy oil development at Lloydminster, and a Mississippian play in the Midale-Estevan area. Husky Oil finally announced plans to proceed with a $3.2 billion heavy oil upgrader near Lloydminster. Frontier activity reached record levels due to a continuation of the federal Petroleum Incentives Program and Esso's major development program at Norman Wells. Significant discoveries were made in the Beaufort region, with oil and gas found in a large fault-bounded structure at Amauligak in the Mackenzie Delta offshore, and the largest wet gas discovery onshore at Tuk on the Tuk peninsula. Other Beaufort oil discoveries at Pitsiulak and a Tarsiut delineation well were not as large as expected. Only one of four Arctic Islands wells, namely a stepout well in the Skate oil and gas field off Lougheed Island, was a discovery. The year 1984 marked a return to better times, and all indications point to even greater drilling activity in 1985.

In 1983, petroleum industry activity in western Canada increased moderately after 2 successive poor years. This increase resulted from record activity in Saskatchewan, a shift from gas to oil exploration, renewed heavy oil development, and provincial government incentives. The total number of wells drilled increased by 7% to 6,755. Exploratory drilling decreased by 14% to 1,973 wells, but was more than offset by a 20% increase in development drilling to 4,782 wells. Exploratory success rate decreased to 62% from 65% in 1982, with 757 oil discoveries and only 461 gas discoveries. The development success rate increased slightly from 89% to 90%, with 3,393 oil completions and 913 gas completions. Exploratory drilling declined in all areas except Saskatchewan, whereas develop ent drilling increased in Saskatchewan, Manitoba, and the Northwest Territories-Arctic. Average well depths increased only in Alberta and Saskatchewan. Total revenue from land sales rose dramatically by 46% to $564 million (FOOTNOTE 4). Alberta land sale bonuses totaled $429 million, Saskatchewan $108 million, British Columbia $26 million, and Manitoba $1 million. Average price per hectare increased substantially in the 3 westernmost provinces, but decreased in Manitoba, exactly the opposite trend from 1982. Alberta exploratory and development drilling continued to decline, but still constituted 68% of western Canadian activity. Significant Devonian reef discoveries were made in the northern half of the province at Senex, Sawn Lake, Gift Lake (Nipisi), and Sturgeon Lake South, and major activity continued at Fenn-Big Valley (Rumsey), Carrot Creek, Valhalla, and Amigo-Shekilie. Two major oil sands projects, at Wolf Lake and Cold Lake, are underway. Two major oil sands projects, at Wolf Lake and Cold Lake, are underway. British Columbia recorded a major Mississippian oil find at Desan, the first major oil discovery in some time from this gas-prone province hard hit by gas surplus and marketing problems. Drilling activity in Saskatchewan soared to record levels and was the prime reason for t e overall increase in 1983 western Canadian activity. Exploratory and development drilling increased, and a total land sale record was established, most of which can be attributed to the Saskatchewan government's incentive program of royalty holidays. Manitoba activity continued its rejuvenation started at Waskada in 1980. Frontier activity was highlighted by a major oil and gas discovery at Itiyok in the Beaufort Sea, and by continued development of the shallow Norman Wells field on the Mackenzie River. Arctic Islands results were disappointing in that a development well at Cisco recovered less oil than anticipated due to structural complications. Major farmouts in the Beaufort Sea indicate continued activity in this area for years to come.

However, evidence of new zircon growth has been found within highly heterogeneous populations of zircon from several greenschist facies slates from the Scottish Highlands. Small (<10 μm), anhedral, unzoned zircons and discrete overgrowths on rounded detrital grains are very common. These new fine-grained zircons have crystallized at temperatures below 350 °C and have been observed only in polished thin sections; they are absent from conventional mineral separates. Typical separation techniques create severe biases in the heavy-mineral populations of metasedimentary rocks, and recognition of the growth of zircon in such conditions may allow isotopic dating of low-temperature events.

Abstract This paper reflects on our mapping and database project britishmonumentsrelatedtoslavery.net , the first and currently most complete account of British representational public monuments related to British transatlantic slavery. It reproduces our headline findings and presents some new maps of the data. However, our main focus in this paper is on placing our project in a wider context of emergent practices and methods that inspired us. First, we note the exponential historical emergence of three connected critical, grassroots ‘counter’ practices across different institutions: of mapping, curating, and ethnography. We frame their critical commonality in their ‘counter’ approach to the nexus of what Benedict Anderson identified as three key ‘institutions of power … census, map, museum’, which have been central to conceiving and executing policy. Second, we prospectively identify some of the common structural causes that underlie this emergent assembly of instituent knowledge‐making practices from below.
Agency in the Anthropocene is premised on knowledge of a situation which challenges human comprehension through its complexity and exceeds the spatio-temporal limits of individual, human-scale experience.It hints at a scale and entanglement of factors that likewise defy conventional mapping and spatial methods.Timothy Morton offers the hyperobject as a description of such objects, and proposed new speculative and phenomenological strategies for their exploration.This raises a complex and daunting question: how can challenges of perceiving-and mapping-the forces at work at morethan-human scale be effectively addressed?In this paper, we propose a digitally-expanded notion of 'Deep Mapping' as a potential
