... As we can see, there are many operating parameters that can impact the production of condensate, and more importantly, the effect of controlling one variable can make a significant impact on another variable. For example, stringent control of RVP can lead to excessive heat consumption causing...

... by geohazards to pipeline infrastructures and the best practices for ensuring the safe and reliable operation of pipeline systems in tropical region were highlighted. Some recommendations for future study include the need for more robust geohazard monitoring technologies, the importance of integrating geohazard...

... Abstract Underground gas storage (UGS) is an important segment in the China gas market. Because of the supply-demand misbalance of natural gas, the gas in underground storage is made available during the peak winter season. The Hutubi (HTB) facility began its UGS operations in a depleted gas...

... Controlled Process (TMCP) steel pipes handling sour gas, stringent requirements have been established for integrity assessment of linepipe longitudinal seam and girth welds. Commonly used reference is DNV-RP-F108 with certain project specifications from operators. This paper identifies the gaps and potential...

... cycle (considering a closed-loop procedure). Real-time solution is then implemented considering operational disturbances from real operations. The methodology was applied to a benchmark case (UNISIM-IV-2026) which is a case based on a typical carbonate field from the Brazilian Pre-salt, with light oil...

... predominantly consisted of seawater elements such as chloride and calcium. The carbon content was unusually higher than supposed general corrosion byproduct which suggested iron carbonate presence from CO 2 corrosion. Even with elevated levels of H 2 S and CO 2 , the flexible riser had been operated...

... was to adjust the system such that it was fit-for-purpose for the operational requirements for the offshore job in Norway. This testing work was subsequently undertaken by the service company's cementing laboratory team in Bergen, Norway. Laboratory Testing Methodology Throughout the laboratory testing...

... operations within predefined parameters while optimizing overall performance. In the conventional approach, achieving optimal on-bottom drilling efficiency necessitates continuous real-time monitoring, intricate analysis for the optimization of surface drilling parameters, and a heavy reliance...

... and obtained a certificate in 2011 that the foreseen qualification plan was compliant with DNV-RP-A203. In 2015, our team was approached by an operator seeking alternative preservation methods. The early engagement phase rapidly progressed towards the decision to launch the EHTF® qualification development...

...Deployment and Installation The overboarding and lowering of Nautilus was carried out by the vessel crane. Nautilus was landed on the pipeline within the marked area observed by the ROV. Successful Offshore Deployment One of the operators has identified the Top of Line Corrosion (TLC...

... hanger, additional cementing job(s), wireline log, as well as wiper and well conditioning runs to prepare the well for the subsequent operation. Drilling Fluid Formulation : The use of this technology drastically reduces or eliminates the use of some chemical products such as asphalt, Gilsonite...

... Consumption stemming from the rig generator, which notably constitutes approximately 85% of the aggregate consumption. Consumption arising from the usage of vehicles and machinery in support of rig operations, encompassing the transport of drilling equipment via vehicles such as the rig crew...

... of the entire reservoir. At the same time, the non-homogeneity easily causes local pressure accumulation, which makes the pore pressure and effective stress distribution extremely unbalanced, and the local pressure accumulation in the formation is a potential threat to the operation of the gas storage reservoir...

... quantity of bulk cement needed for the operation would have been 565 t. This posed a significant logistical issue, as the drillship's usable silo capacity was 540 t, split across 4 silos. Operationally, this would have meant transferring an additional 30-50 t from the supply vessel to the rig silo during...

... and pre-commissioning may approach atmospheric pressure, resulting in even lower initial temperature (well below −50°C). Abstract The first introduction of carbon dioxide (CO 2 ) into a new carbon capture and storage (CCS) pipeline is one of the most onerous operations over the asset lifecycle...

... initially permitted safe high-pressure drill stem testing operations using the drill pipe. Subsequently, MTM RSC [ 7 ] has been used for drilling [ 9 ], [ 11 ] , workover and completion operations [ 10 ], [ 11 ], [ 12 ], [ 13 ] , and intervention riser applications [ 12...

Abstract The oil and gas industry...

... characteristics that will likely shape the operating model and how the CO 2 is treated, conditioned, transported and stored. Abstract Pre-commissioning of conventional subsea production and injection system is well established and has been delivered reliably by offshore contractors. However, subsea CCS...

..., making it unfeasible for operational use. Thus, the design must aim to minimize slip changes while remaining operationally feasible and efficient. As mentioned above, extensive studies on deepwater operations were conducted to assess operation sequences, slip change frequencies during well operations...
