Ceasefire
The Nigerian government is planning a peace summit with Niger Delta militants in the capital Abuja next month.
Their chosen mediator, UN Deputy Secretary Ibrahim Gambari, announced he would seek a 90 day truce to allow the summit to go on "in an atmosphere of calm".
Mend announced on Sunday it would begin began a ceasefire on Tuesday night, but it still refuses to participate in the peace conference unless one of their leaders, currently on trial for treason and gun-running, is given an amnesty to participate.
On Wednesday, the group said they chased off a group of military gunboats from near one of their camps in Bayelsa, hours before they were due to commence the ceasefire.
"As our fighters approached in over fifty war boats, the eight gun boats turned and fled from the area thereby averting a clash and maintaining the on-going ceasefire," the group said in an e-mail to journalists.
A military commander told Reuters news agency they were conducting surveillance on the group of militants responsible for the attack on the Bonga field.
"We had intelligence reports that the camp was responsible for the attack, so we went after them," he said.
It was unclear if there had been any casualties.
Big business
Also at the weekend, violence erupted in the Bayelsa state capital Yenagoa as two separate militant groups clashed, killing at least six, Reuters reported.
Correspondents say that violence is big business cross the Delta region.
Groups of unemployed, armed youths are involved in oil theft, extortion and kidnapping.
Mend, the most publically visible militants, is a loosely affiliated group of factions, some of which have been on ceasefire for almost a year.
In e-mails to journalists, Mend demands a bigger share of the oil wealth, but there are many more armed youths who see the pipelines that cross the Delta as an easy way to get money and power, correspondents say.
