The company did not immediately respond to a request for comment on Monday morning.
According to Bloomberg, BP is now "putting together a plan to plug the gas leak". Soon after, they determined that the well was also spraying a mist of crude oil.
Shares in BP were down 2.3% at 460.15 pence Tuesday.
Alaskan and federal officials had identified two leaks spewing methane gas which is linked to climate change.
Neither injuries nor impacts to the wildlife have been reported.
Alaska Department of Environmental Conservation spokeswoman Candice Bressler says the well operated by BP Exploration Alaska Inc., a subsidiary of BP, was successfully controlled overnight.
It is still unclear, how much oil has spilled. The production of the North Slope rose to about 565,000 Barrels per day in the month of March, which was the highest since the year 2013's month of December. "This really needs to be thoroughly investigated to find out what went wrong and whether there's a danger of it happening again". The department said in an update that the village "has been notified of the incident and is receiving situation updates via these situation reports". That movement broke a well pressure gauge and temporarily delayed efforts to close off the well, the state said.
The total amount of oil spilled and whether the crude affected the snow-covered tundra nearby isn't yet clear, though authorities have expressed confidence the crude contamination is contained with a gravel area directly surrounding the well site. The well has been shut in since Friday.
The crude spray onto the well pad, which occurred while the well in the Greater Prudhoe Bay area was venting gas, had stopped by Sunday afternoon.
A subsidiary of BP is reporting a crude oil spill on Alaska's North Slope.
The Alaskan North Slope crude was valued at a per barrel value of $1.9 over the U.S. benchmark West Texas Intermediate on 13th April.
