Abstract Overview North Caspian Operating Company N.V. (NCOC) is the operator of activities under the NCSPSA (North Caspian Sea Production Sharing Agreement) formed to explore and produce hydrocarbon within the 5,600 square kilometer including the giant Kashagan field, one of the largest petroleum developments in the world. The Kashagan field is located in the Kazakhstan sector of the Caspian Sea and extends over a surface area of approximately 75 kilometers by 45 kilometers, in stages with the first element designed to produce around 450,000 barrels/day. The water depth in the development area is less than 4m and is ice bound during the winter season. The development of Kashagan, in the harsh offshore environment of the northern part of the Caspian Sea, represents a unique combination of technical and supply chain complexity. The combined safety, engineering, logistical and environmental challenges make it one of the largest and most complex industrial projects currently being developed anywhere in the world. The Kashagan Field Development Project is an extremely complex development in respect to the technical issues associated with developing a high pressure, sour hydrocarbon reservoir in a hostile environment. Beyond oil and gas, NCOC believes that NCSPSA activities can and will bring many benefits and opportunities to Kazakhstan. The Kashagan Laboratory Services have numerous responsibilities for the analysis of the complete range of fluids and chemical associated with the production operations. These include reservoir fluids, plant process fluids, plant products and by-products and waste. The laboratory also assess emissions to the environment by production and process streams and monitor a wide range of environmental substances which are considered relevant to Kashagan operations. Other functions include the support of equipment condition monitoring with the analysis of lubrication oils, grease and another condition related materials and fluids. Onshore Chemical Laboratory is central repository for all laboratory activities. An onshore production laboratory provided in the Eskene West area (Samal camp) to undertake all required complex analytical testing. It is envisaged that the onshore laboratory shall additionally carry out all future Kashagan development testing and analysis. A second production laboratory provided on D island where utilized very basic laboratory analysis. It is incumbent upon any prudent operator to measure the chemical composition of the products and by-products that it produces. Measurements collated are used to certify to regulatory authorities and Joint Venture partners that product chemical content is within agreed specification parameters. To achieve the very high specifications and standards of measurement required a Production Laboratory containing specialized and certified laboratory equipment has become a feature of most production facilities. When appropriately configured and connected to the laboratory equipment a Laboratory Information Management System LIMS software application is used to define and manage the procedures, schedules, capture, storage and reporting of data from various measurement scenarios and physical equipment within the Production Laboratory. LIMS supports the laboratory work and provides timely and accurate information to plan operators, managers and other relevant groups within company, its partners and government and regulatory bodies. LIMS system is also receiving store and report data from online plant analytical instrumentation for validation purposes.

Abstract Smart field instruments (sensors & valve positioners) are the main digital data source required for modern day predictive data analytics tools and frameworks. Apart from communicating the measurement value, there are many additional features available within the smart field devicessuch as sensor diagnostics, remote set up, commissioning, trouble shooting and calibration, all within the same 2 wire used for the signal communication. This paper summarizes the challenges faced in the journey of realizing the benefits of smart field instruments diagnostics using Highway Addressable RemoteTransducer (HART)open protocol as part of Instrument Asset Management System (IAMS).
Pressure waves, whether generated by humans or by natural processes, are a fundamental tool in the exploration of the Earth. The interaction between pressure waves and subsurface structures is complex, and diagnosing structure from observations of pressure waves is an active area of research. Many early studies of pressure waves and harmonic oscillations were motivated by a fascination with musical sounds, and musical instruments are still an excellent modeling system for exploring pressure-wave dynamics.

ABSTRACT: This paper mainly focuses on the quality of crustal strain observations. Carry on works in standard, metrology and quality inspection three aspects to establish a quality assurance system ensures crustal strain instruments have corresponding quality assurance measure in production, station construction and routine operation is elaborated. The quality of crustal strain observation will be improved significantly. Accurate and reliable data can be provided for earthquake prediction and seismology research. 1 INTRODUCTION Geological mechanics theory created by LI Siguang had successfully guided the development of several major oil fields such as Daqing and promoted the exploit of China's oil and other mineral resources. His theory also demonstrated a clear direction of earthquake prediction research. According to the geological mechanics theory, crustal stress state is one of the most important characteristics of the crust. Accurate determination of crustal stress state and diversification is not only important basis of earth science and its relational subjects but also is scientific basis to discover formation mechanism and prediction of multiple geological disasters, earthquake gestation particularly. Major contradictions of caused earthquake are contradiction of crustal stress and rocks against tension. Li Siguang had Emphasized that crustal stress diversification should be carefully observed on the basis of research of tectonic activity in seismology research. In 2lth century, U.S Government's "Earth- Scope Project: Plate Boundary Observation (PBO)" White Paper indicates that borehole strain instruments are the ideal instruments for continuous observation to reveal crustal deformation in short time (from several seconds to several months) and can play a major role in the observation when or before earthquake and volcanic eruptions. 2 BOREHOLE STRAIN INSTRUMENTS Borehole strain instruments divided in three types: The first is volumetric borehole strain instruments. According to volume changes of cavity mounted in the instrument, the relative change in rock volume can be obtained.
