Stakeholder engagement management officer Rosie Birungi said families whose crops were destroyed during the survey will be fully compensated.
Speaking at a media briefing in Kisumu town on Monday, she said the compensation will start by the end of this month and concluded by the end of July.
Birungi said those affected will be paid depending on their crops. The most affected areas are Nyakach, Muhoroni and Nyando constituencies where the company carried out an extensive survey.
Some of the crops damaged include sugarcane, maize, sorghum and vegetables. Birungi said the company is conducting damage assessment to ensure nobody is left out in the compensation.
The said it will compensate landowners in cases of acquisition or loss of land, an issue that had been of concern to most elders.
MPs Aduma Owuor (Nyakach), James Koyoo (Muhoroni), Fred Outa (Nyando) said residents and leaders must be properly engaged to avoid conflicts.
Tullow social investment manager Ben Miranga said the company has allocated Sh5 million for bursaries and Sh15 million for community water projects.
He said last year more than 200 children in Kisumu, Kericho, Homa Bay and parts of Nandi counties benefited from Sh3 milliion bursaries.
Miranga said four out of 25 students from Nyanza region have benefited from the Tullow group scholarship scheme to undertake oil and gas courses.
“Out of the 24 scholarship awarded in 2012 and 2013, four of the students were from Kisumu and other neighbouring counties,” he said.
Mirangi said other students were also selected across the country especially in areas Tullow is undertaking exploration. The company plans to expand oil exploration to Western Kenya following a successful completion of a survey commissioned two years ago.
Birungi said the success rates of the exploration are still unknown as the seismic analysis and exploration drilling would be completed in a few months.
She added that detailed surveys on the prospect would still continue in various phases in the three constituencies before actual works begin.
Birungi said the exploration could take up to 10 years before actual production starts thus calling for patience among the residents.
The works on in Nyanza site, under block 12B, were started in February 2012 to add to the Ngamia wells in Turkana among others in parts of Rift valley.
