Official Data

Many studies, like the influential BP Statistical Review of World Energy 2004, notice a worlwide growth of oil-reserves. But there are many reasons to mistrust the official data: They use their own questionable definitions of "oil reserves", mixing conventional and unconventional reserves. Moreover the growth of oil-reserves, which is shown in the statistics, is based more or less on a reassesment of the existing but not on a discovery of new oil-fields. Due to these deceptive practices, the "Assosiation for the Study of Peak Oil" has published a new study with the result that it can find only 780 billion barrels of proved oil worldwide, instead of the 1147,7 billion barrels that BP claims in its statistics.

Development of the Cossack and Wanaea oil fields is in progress with first oil scheduled for late 1995. Wanaea oil reserves are estimated in the order of 32 x 106m3 (200 MMstb) making this the largest oil field development currently underway in Australia.Development planning for these fields posed a unique set of challenges.Key subsurface uncertainties are the requirement for water injection (Wanaea only) and well numbers. Strategies for managing these uncertainties were studied and appropriate flexibility built-in to planned facilities.Alternative facility concepts including steel/concrete platforms and floating options were studied-the concept selected comprises subsea wells tied-back to production/storage/export facilities on an FPSO located over Wanaea.In view of the high proportion of costs associated with the subsea components, significant effort was focussed on flowline optimisation, simplification and cost reduction. These actions have led to potential major economic benefits.Gas utilisation options included reinjection into the oil reservoirs, export for re-injection into North Rankin or export to shore. The latter requires the installation of an LPG plant onshore and was selected as the simplest, safest and the most economically attractive method.

For the conditions of an oil fields group characterized by an insufficiently high degree of oil reserves recovery, an algorithm for objects identifying using parameters characterizing the objects’ geological structure and having a predominant effect on the oil recovery factor is proposed. The proposed algorithm allows us to substantiate and use the analogy method to improve the oil production facilities management efficiency by targeted selection of the information about the objects and processes occurring in them, removing uncertainties in low density conditions, the emergence of real-time decision-making capabilities, determination of optimal ways of current problems solving, reducing the probability of erroneous decisions making, justifying the trend towards the goals achieving.

Development of the oil industry in Kazakhstan at the current stage is characterized by a decrease in the quality of the raw material base. In the total balance of fields under development, the fields that have entered the late stage of development prevail and, consequently, there is a significant deterioration in their structure, an increase in the share of hard-to-recover oil reserves, watering of beds and well production.One of the main challenges during the development of the field is the deposition of inorganic salts in the oilfield equipment. This article describes the main reasons for the formation of solid inorganic deposits in oil fields, methods of scale inhibitors, as well as the classification of scale inhibitors. Presents the physical and chemical characteristics of the objects under study: the properties of oils and watersof Uzen and Zhetybai oil fields and the chemical reagents – inhibitors of scale formations. Based on the results of laboratory studies, scale inhibitors were selected, which showed high efficiency (90 - 100 %) to prevent the precipitation of CaCO3, CaSO4 and BaSO4 under the conditions of Uzen and Zhetybai oil fields. The study was conducted in the center of scientific and laboratory research branch of KMG Engineering LLP "KazNIPImunaygas".

Despite the current political and economic situation in Russia, mining in small oil fields is important and topical issue. We have conducted a geological and field analysis of the development of one of such small oil fields from setting into operation to shut down and have identified the reasons for the low production of oil reserves and the failure to achieve the design oil recovery factor. At the same time, the field has sufficient reserves of recoverable reserves, and there is an available transport infrastructure, which proves the necessity to consider rerun it for the development. For this purpose, geological and technical actions have been developed and are being proposed for implementation to improve the efficiency of field development. These actions envisage implementation in two stages: the first with minimal costs and the second with higher costs. At the first stage, at the existing reservoir pressure, we recommend to perform forced fluid withdrawals with an increase in depression on the reservoir. At the second stage, we offer actions at a higher cost, such as hydraulic fracturing, sidetracking. As a result of the analysis, actions have been developed to increase selection from initial recoverable reserves and increase the economic efficiency when the field is rerun.

The Moment

Imminent climate change is indeed an “inconvenient truth” that will oblige us to alter our energy use long before we begin to experience any shortage of crude oil or natural gas. Warnings about our climate come at a time when nothing would otherwise appear to stop us from using fossil energy sources for several more decades. Indeed, never before in the history of our civilization has the outlook for our continuing use of mineral oil looked so comforting. In the early 1970s, there were only 25 years’ worth of known oil reserves at the consumption levels of the time. Now, at the end of the first decade of the twenty-first century, we can look forward to 42 more years of oil, even though consumption rates have almost doubled in comparison to the 1970s. Newly discovered oilfields and technologies have more than compensated for increasing demand. Known reserves are now at their highest level since we began to keep systematic statistics. That doesn’t mean that progress with regard to our energy supply will be smooth; changes come in shocks, as we will see in this chapter. We are likely to witness crisis after crisis in the years ahead. And the tangible heating of our Earth will make the crises worse. There has been a passionate worldwide debate for decades now about the precise timing of peak oil—the moment when oil production hits its maximum level and then begins to decline until there is no longer any left that is economically viable to extract. Yet peak oil predictions invariably prove incorrect. Each time, it turns out we can extract more oil from the ground than we previously thought. One alarming calculation after another has fallen by the wayside, as we also showed in the introduction to this book (chapter 0.2). Outbreaks of panic well up with each new wave in energy prices. Just before the credit crisis of 2008, oil prices were at a record high, and prophecies of the end of the oil era were abundant.
