Oil Company Uses SAGD for Heavy Oil Recovery

An oil company which regularly drills into reserves containing heavy crude oil required an advanced data logging system to monitor their operation. This crude is commonly harvested by drilling a horizontal well into the deposit and injecting steam into it to heat the bitumen and allow it to flow more smoothly. A second horizontal well is then drilled directly below the original to collect the oil and pump it to the surface, an involved process known as Steam Assisted Gravity Drainage (SAGD). These wells are connected by long pipelines to the refinery itself for processing. Optimizing harvest efficiency is critical given the sheer volume of oil pumped from these reservoirs, requiring a powerful data logging solution to monitor the oil well temperatures. This is needed for both efficiency and safety reasons – any increase in temperature could cause a blowout, while sudden decreases often lead to wasteful pumping inefficiencies. Modem connectivity is therefore a must for connecting these loggers to a central computer for ease of reference. Continue reading …
