At the start of Tengizchevroil joint venture in 1993, the company created a five-year, $50 million dollar program called Atyrau Bonus Fund. TCO saw the program as a way to create value both for the company and the community. Furthermore, TCO decided to work collaboratively with the Atyrau Oblast Akimat leadership in choosing the social infrastructure projects in Atyrau Oblast to be funded with Tengizchevroil funds. In 1998, the Atyrau Bonus Fund program was concluded as planned. The objectives of the program were met and the outcomes clearly pointed to the value of, and need for, such a program.
As a result, in 1998 TCO established the Egilik (Kazakh for benefit) program. Egilik began with a $4 million budget, growing steadily until 2003 when the budget increased to $8 million for three years and then to $12 million for another three year period. For 2009 through 2012 the budget was $20 million per year. The increase coincided with the finalization of the latest Tengizchevroil production expansion. The majority of funds - $61 million - have been dedicated to replacing the water system in Kulsary, the nearest population center to the Tengiz field and home to many TCO employees and contractors. TCO health and social impact assessment studies of the region demonstrated that the Kulsary water quality was low and water service undependable. The water system replacement project took 4 years and allowed TCO to address objectives in a key thematic area of its Community Investment Program (CIP) – health.
Over the life of the program, TCO has funded various social infrastructure projects for Atyrau Oblast including schools, hospitals and clinics and electricity and water systems. At the end of 2012, TCO has invested nearly $200 million through the Egilik and Atyrau Bonus programs since 1993.
