... ABSTRACT When a deep water high temperature and high pressure well delivers fluid upward, the casing column undergoes thermal deformation, and the circumferential fluid generates circumferential pressure, resulting in wellhead lift. In this paper, the temperature field of deep water high...

... an important role in the offshore oil and gas development. A coupling strength analysis model for drilling riser and subsea wellhead was proposed under extreme environment condition. A stack-up for drilling riser system under 3000m water depth is established and safety operation criteria for the drilling riser...

... development of these oil and gas resources has been challenging. However, the utilization of a self-developed, simplified subsea production system has made it possible to exploit these reserves. In the shallow-water subsea wellhead development model, we have opted for an operational approach that combines...

... ABSTRACT Oil and gas drilling in polar tundra has the problem of wellhead destabilization and sinking caused by permafrost thawing. In this paper, the water content of the soil around the surface conduit, the upper wellhead load and the temperature of circulating liquid in the wellbore...

... of shallow-water subsea wellhead system should be the primary concern in this new mode. Three separate well configuration stages, namely as drilling with 30" riser, drilling with 20" high pressure riser and completion, are analyzed. Assessments include axial capacity, strength, wave fatigue and VIV fatigue...

... ABSTRACT In the process of deep-water offshore oil and gas exploration and development, it is necessary to have a complete subsea production system. The subsea tieback wellhead system is one of the core equipment in the floating drilling unit and subsea production system. During long-term...

... ABSTRACT Large lateral displacement and bending moment of marine drilling conductor are produced under loads such as wave, current, and ice, which seriously threaten the safety of offshore operations and wellhead stability. Due to soil disturbance, the bearing capacity of the drilling...

... ABSTRACT Underwater wellheads are the basis for deepwater oil and gas field development and carry the weight of various pipe strings and tools in the well. The suction pile wellhead designed by combining a cylindrical foundation with the underwater wellhead can greatly improve the bearing...

... ABSTRACT The surface conductor is a key equipment in deep-water drilling. They are connected into a large-diameter pipe string. The friction between the conductor and the seabed soil should be relied on to support the subsea wellhead. The new type of surface conductor has been done to shorten...

... ABSTRACT To maintain the stability of subsea wellheads, the complex wellhead loads need to be analyzed. A mechanical method is proposed to calculate these wellhead loads during wellhead installation and well production. Case studies show that wellhead sinking can occur during the process...

... ABSTRACT Dynamic response analysis model of subsea wellhead affects the efficiency and accuracy of fatigue assessment. There are three models for dynamic response and fatigue damage assessment of the subsea wellhead, i.e., fully coupled, semi-decoupled and decoupled. Based on the analysis...

... ABSTRACT With the development of drilling in deep water, the Riserless Mud Recovery System (RMR) shows the huge advantage. Relative to the riser drilling, there is less research of analysis for the string and wellhead stability. This paper analyzes the whole loading of the drilling pipe...

... the well by strict technical procedures. The top level of well head should be 4m below the seabed base on the requirements of State Oceanic Administration (SOA). It is necessary to check the wellhead for safe when the well is filled with concrete. In general, the wellhead is buried under the seabed deeply...

..., the stability of subsea wellhead is threatened. Besides, if the vertical bearing capacity of conductor is insufficient, serious consequences, such as wellhead sinking, even the wellbore abandon, would occur. So the bearing capacity of conductor is of great significance for the wellhead stability and deep-water...
