  • Design and drilling of wells in formations with high pressure

    Vojin Solomun (2024)
    Objectives of this Thesis are to: - Develop an awareness of the challenges presented from elevated temperatures and pressures in well construction. - Learn the key differences between ―normal‖ condition wells and HPHT wells. - Understand some of the indicators of thermal- and pressure-related problems. - Understand the responses which may be made to mitigate high pressure and high temperature ,,HPHT‘‘ challenges while drilling wells. HPHT wells are an unavoidable consequence of the ever expanding search for oil and gas resources around the world. As wells are ...

WELL CONTROL Successful HPHT Well Control consists of: HPHT challenges; Primary Well Control - PPEG, managing the well, swab & surge, ECD & ESD, fracture charging; Secondary well control - kick detection and response, kick control procedures, phase behavior; Tertiary Well Control - ...
    ... drilling the well and defined in the WCPP. A specific decision tree should be made for the well to cover the alternative well control methods and at what point the well is shut-in to re-evaluate the situation. Criteria for the decision to abandon the well must be established as part of the well control ...
    ... assessment of well integrity risks associated with the intended operation shall be performed. The risk of a well integrity failure or well control incident shall be assessed. When evaluating well integrity risk, the failure modes of the primary barriers and the availability of secondary well barriers ...

  • Application of machine learning for diagnosing the operation of a deep well pump in oil production

    Maja Trikić (2024)
    This paper will thoroughly examine how machine learning can improve the diagnosis of deep well pumps by analyzing the role and function of the pumps, dynamograms, sensor technologies, and diagnostic methods.Our analysis will provide insights into modern techniques and approaches for enhancing the performance and reliability of oil production systems, targeting cost reduction and increased operational efficiency.
