Three oil and gas companies are seeking legal protection from convicted oilpatch bomber Wiebo Ludwig.

EnCana Corporation, Canadian Superior Energy and Seaview Energy want peace bonds issued against Ludwig, his 29-year-old son, Benjamin, and his friend Richard Boonstra.

According to police, the energy firms are concerned that Boonstra and the Ludwigs will destroy company property and harm their staff.

They three men were served summons on Saturday. They are scheduled to appear in a Grande Prairie, Alta., court next week.

A hearing will be set to determine whether there's enough evidence to support the companies' allegations.

From his farm in Hythe, Alta., Ludwig told CTV Edmonton that the three men were being unfairly targeted.

"We will try to appeal to the judge's humanity, but when it comes to law there isn't much, there isn't much to appeal to," Ludwig said. "They've got it all fixed. People on the land have very little room to make a case against industry and the danger it poses."

"They are more dangerous to us than they can imagine us being to them," he added.

RCMP said evidence cited in the peace-bond application pertains to events that took place over a long period of time in Alberta.

Ludwig was convicted in connection with two Alberta gas-well bombings that took place in 1998, and served 28 months in prison.

He has long claimed that oil and gas development near his land have harmed the health of his family and the animals on his farm near Hythe.

The Mounties have been investigating a series of bombings since October of 2008 that targeted EnCana pipelines.
