The mechanism and reasons for the decrease in injectivity and corrosion of wellbore and surface pipelines caused by early...

.... Capacity Design The conditions of CO 2 entering the CCS onshore compression facility and the conditions of CO 2 being transported through the subsea pipeline after compression are as follows and were used as key boundary conditions for this study. The average CO 2 output through the compression...

... There is an apparent trade-off between transport costs and compression costs when considering the supply chain for blended and separated hydrogen. For a visualization of this trade-off see Figure 5 , where the different pressure levels along two different supply chains, i.e. pipeline transport...

... have been made using ALFAsim, a 1D multiphase flow simulator developed by ESSS ( ESSS, 2019 ). Parametric analyses were performed on steady-state scenarios to investigate the optimum pipeline and wellbore diameters respecting the erosional velocity of American Petroleum Institute (API). Also...

..., including topside modification, conversion of existing water injection pipeline as temporary gas lift line, as well as installation of unconventional artificial lift methods to temporarily replace gas lift as an artificial lift for Field C. After extensive analysis and evaluation, the team settled...

... source situated on a single platform to infuse wells located across various platforms. This leverages the pre-existing pipeline infrastructure that interconnects these platforms. The facility integrity assessments and engineering modifications is needed for activating inter-platform gas lift in mature...

... (ratio 50:50) to meet 8 mol% CO 2 limit at pipeline from Platform X to gas processing hub (Platform Y). In a normal production, only two (2) NAG wells flowing, two (2) NAG wells remain idle causing a loss in production opportunity. The study was conducted to further unlock NAG potential by revisiting...

... Multiple abnormal scenarios were considered such as Acid Gas Removal Unit (AGRU) upset and reduced or cessation of on-spec gas export into pipeline conditions. Results from these transient simulations were verified with numerical method approach for H2S diffusion modelling. The H2S scavenger...

... Abstract Currently the material selection of carbon steel pipeline for oil and gas field is restricted according to sulfide stress cracking (SSC) severity diagram in ISO15156-2 standard. Nevertheless, there is undefined zone between non-sour and sour region in the mentioned specification...

... platform platform design marginal resource pipeline installation Introduction Sisi and Nubi are two gas fields located 25 km offshore the modern Mahakam delta and 30 km to the southeast of the Tunu field ( Figure 1 ), at 60-70m of water depth. Sisi field was discovered in 1986 and Nubi in 1992...

... integrated asset model to meet the anticipated gas delivery targets. Next, the subsurface model was integrated with a multiphase transient network model to show how it can be used to evaluate the risk of hydrate formation along the pipeline during planned production start-up. As a final step, in-built...

... Abstract Offshore terminal usually performs crude oil lifting process regularly every 7-8 days. However, three repetitive leaks in crude oil subsea pipeline 36" MOL SPM-1 to SPM-2 occurred in the offshore terminal area had stopped the natural oil lifting process. Due to complex conditions, leak...

... in seafloor. In this study, a transient temperature and pressure calculating model was established to predict the risk of hydrate reformation in production pipelines during offshore natural gas hydrate development. Using the proposed model, the region of hydrate reformation in gas hydrate production wells...

... Abstract Kedung Keris (KK) is a sour oil field based in Cepu Block, Indonesia. KK field was originally planned to have a processing facility with separate pipelines to deliver crude & produced water, while the gas was planned to be flared. To reduce cost, this concept was changed...

... Abstract Hydrate-associated issues are of great significance to the oil and gas sector when advancing the development of offshore reservoir. Gas hydrate is easy to form under the condition featuring depressed temperature and elevated pressure within deep-water gas pipeline. Once hydrate...
