The land survey system was introduced in 1910 and was based on the Dominion Land Survey algorithm. Furthermore, the surface and bottom coordinates of a well are defined as distances from the closest sectionboundary. This nomenclature is based on the Alberta Township System for wells in Manitoba, Saskatchewan, Alberta and the Peace Country in north-western British Columbia. Provincial governments in Western Canada regulate the naming of oil and gas wells, by assigning unique well identifiers(UWID) to each drilled hole. Initially used to define land for agriculture purposes, the system was later adopted in land sales and leases for hydrocarbon exploration rights. Sections may be further subdivided into quarter-sections (160 acres),quarter-quarter sections (40 acres),or any other mathematical subdivision.The gray square in the figure on the bottom right might be described as “the northeast quarter of the northwest quarter of the southeast quarter of Section 14, Township 2 North,Range 3 East of the 6th Meridian.The Alberta Township System is a land survey system used in Western Canada to divide land in 1 square mile sections. Land is typically divided into 6-milesquare townships.Townships are described with reference to their principal meridian and base line.Įxample: A township “2 North, Range 3 East, Mount Diablo Meridian” would mean the township is in the second tier north of the base line, and the third column east of the Mount Diablo Principal Meridian.Įach township is then divided into 36 sections.Each section is 1 mile square and contains approximately 640 acres, makingallowance for unsophisticated measuring tools employed at the time of creation. Land is described as being east or west of the principal meridian, and north or south of the range line associated with that meridian.
Each principal meridian has a base line that runs east and west through it. A way of subdividing and describing land in most of the United States.Texas, Hawaii, and most of the original 13 states are not described by the PLSS.The system starts with a principal meridian, which is a north-south line.There are 37 principal meridians in the United States.
