82 There needs to be a steady reduction in the nation’s reliance on imported technology and greater technology adaptation to create drilling equipment that better suits local needs. By overcoming the challenges in this area, Kazakhstan stands to become the drilling industry leader in the Caspian region. Kazakhstan Upstream oil & gas technology and R&D roadmap
4.1 Drilling and well costs Challenge commentary Kazakhstan has some of the most complex reservoirs in the world, containing oil and gas at high pressures and temperatures, as well as high levels of H 2 S and CO 2 . Drilling is always going to be a challenge under these conditions. On top of this, there are the practical and logistical difficulties associated with the limited internal infrastructure in parts of the country, lack of a sea route for drilling equipment into the country and the harsh winters. Under the circumstances, rig safety is a major challenge in Kazakhstan, undertaking exploration or development drilling or well intervention in a manner that reduces the risk to the people involved as well as local communities. The challenge is most acute in fragile formations and where there are issues of well integrity – the Kenkiyak, Korolev, Kumkol South and North Buzachi fields are examples. Casing pressure management is also a safety-related issue in many fields, especially in sedimentary sub-salt reservoirs such as Karachaganak, Kenkiyak, Zhanazhol and Alibekmola. Drilling through low pressure zones is a widespread challenge, given the prevalence of carbonate reservoirs in Kazakhstan and their tendency to contain cavities (vugs or karsts) or otherwise low mechanical strength rock structures. Mud loss, well bore stability and pipe sticking are common problems in, for example, Karachaganak, Kenkiyak, Kumkol South and North Buzachi. Given the drilling challenges faced in Kazakhstan, well costs are generally high. Drilling in shallow water generally entails the construction of concrete drill pads. But the main cost issues arise from the need to bring every element of the drilling process (rigs, tools and equipment, chemicals and, not least, skilled people) into Kazakhstan. Unsurprisingly, cost over-runs are common: reducing their likelihood is a big challenge.
