As recently as 2007, North Dakota ranked 8th among the states in oil production. In 2008, the state overtook Wyoming and New Mexico; in 2009 it outproduced Louisiana and Oklahoma. North Dakota surpassed California in oil production in December 2011, then in March 2012 overtook Alaska, to become the number two oil-producing state in the country, exceeded only by Texas. The North Dakota state government receives through severance taxes 11.5 percent of the gross value of all oil produced. The boom has given the state of North Dakota a billion-dollar budget surplus. In addition to severance taxes, the state of North Dakota owns extensive mineral rights, which are leased by competitive bidding. In fiscal year 2010, the State Land Department reported that mineral income on its land earned $265 million for the North Dakota school trust fund, and that the trust fund had grown to $1.3 billion. The federal government is also a major owner of mineral rights in the region, and leases the rights to companies in competitive bidding. In a January 2013 federal lease sale, the top bid was $19,500 per acre for a lease on one tract in North Dakota. Of the lease sale and royalties from the federal tracts, the federal government keeps 52 percent, and passes 48 percent on to the state of North Dakota. The industrialization and population boom has put a strain on roads, water supplies, sewage systems, and government services in the area. Some counties have increased in population by almost double from 20,000 to 40,000. The boom has brought with it increases in crime and social problems. The addition of thousands of oil workers has led to a housing shortage, requiring the construction of camps for housing them. Law enforcement agencies have reported sharp increases in offenses, particularly violent crime, drug trafficking, gun crimes, and prostitution. These problems are similar to those found in other regions in which energy industry workers have taken temporary jobs. Law enforcement agencies can and are collaborating to meet the challenge, but there is also a shortage of officers, when pay for oil workers is two to three times that amount. As of October 2013, the FBI's Project Safe Bakken had stationed additional full-time agents in the area. The boom has seen dramatic increases in the infrastructure of Western North Dakota. Examples of oil industry related infrastructure investments in Williston, North Dakota are the multi-acre branch campus of Baker Hughes, the Sand Creek Retail Center, Jim Bridger shops & offices. The oil boom's effect on families is the subject of the Academy Award-nominated documentary short film, "White Earth".
