The Alberta Township System is a land survey system used in Western Canada to divide land in 1 square mile sections. Initially used to define land for agriculture purposes, the system was later adopted in land sales and leases for hydrocarbon exploration rights. Provincial governments in Western Canada regulate the naming of oil and gas […]

Well classification

Lahee classification Mnemonic Lahee classification Description NFW New Field Wildcat An NFW well is located at a considerable distance beyond the limits of known pools and is outside the boundaries of existing fields. The well is drilled in an area where hydrocarbons have not yet been discovered. The geological risk of this type of well […]

Preparing cuttings samples drilled with invert mud

Invert (oil based) mud poses very specific challenges when it comes to cleaning drill cuttings. Invert mud coats the cuttings in a sticky membrane; in order to eliminate this, the coating has to be dissolved with thinners and shaken off using kinetic energy. Most cleaning methods are time consuming and require large quantities of water […]

Glossary of Geosteering terms

Directional drilling is becoming the predominant method of opening up reservoirs in the mature Western Canada Sedimentart Basin. Wellsite geologists are supervising and controlling the wellpath in order to achieve maximum exposure to the reservoir or to hydrocarbons within a reservoir. Strong understanding of directional drilling terms is paramount in this capacity. Glossary of geosteering terms […]
