The complete paper presents the results of evaluation of laboratory and demonstration trials of HDPE liner to mitigate premature failures and prolong the run life of production tubing. Corrosion inhibitors are often the first line of defense against internal corrosion, and effective mitigation relies on proactive monitoring and management of these inhibitors to allow for regular feedback and dose adjustment. This paper describes a novel method of chemical dosage based on time-resolved fluorescence (TRF) that allows a simple, accurate, and efficient quantification of chemicals below parts-per-million ranges, even for double (scale/scale, scale/corrosion) quantification. A study done to find the root cause of coiled tubing string failures in Montney indicated microbial-induced corrosion, leading the CT service provider to create a biocide treatment program. Rigless coiled-tubing-unit (CTU) interventions can be effective in returning to production wells that have lost electrical-submersible-pump (ESP) efficiency because of organic, inorganic, or mixed scale deposits.
This paper presents a methodology to estimate the probability of failure of every individual corrosion defect and the residual likelihood of failure of an overall corroded pipeline segment after selected repairs, using structural probabilistic analysis. In this paper, a data-driven model is applied to derive optimum maintenance strategy for a petroleum pipeline. The model incorporates structured expert judgment to calculate the frequency of failure, considering various failure mechanisms.
This paper reviews the mechanisms of initiation and the prevention of top-of-the-line corrosion (TLC). Recent research and developments are highlighted and validated to arrive at best practices for control of this significant corrosion manifestation. Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
The methodology is the industry’s first to address CUI. Along with DNV GL’s new technology, maintenance costs may be reduced by up to 50%. With these synopses of technical papers from OnePetro you can join the author for conferences in Kuala Lumpur, New Orleans, and Lagos, all while sitting in your chairs and without any travel expenses. This paper reviews the mechanisms of initiation and the prevention of top-of-the-line corrosion (TLC). Recent research and developments are highlighted and validated to arrive at best practices for control of this significant corrosion manifestation.
The natural gas pipeline is co-financed by the EU, with work beginning immediately. The hunt for global alternatives to store crude oil includes offshore, global strategic reserves, pipelines, rail cars, and trucks. Westcoast Energy revised its inspection practices following the 2018 incident. Shell has begun to examine the innovative technologies that could shift the inspection paradigm. Delfin Midstream announced advancements in partnership with Samsung Heavy Industries and Black & Veatch.
The deal follows BP’s divestment of its global petrochemicals business in late June. Designed to be a “living” map, it focuses on the largest fixed infrastructure for crude oil and refined products such as trunk pipelines, refineries, and storage facilities. Supreme Court upholds ACP’s controversial permit to lay pipe under national forest and across two states. McDermott’s completion comes 19 months after it was first awarded. SapuraOMV achieved first production from the Larak gas field in January.
Approved in October, the Flow Measurement Technical Section will help engage the greater SPE technical community in flow-measurement-related issues and technologies. It will cover the full spectrum of flow measurement, including single-phase and multiphase flow. At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective. To facilitate testing and comparison of products that attenuate microbially influenced corrosion under field conditions, a method using microorganisms from a low-tide, anoxic North Sea sample was developed that allows corrosion measurements to be made for corroding biofilms grown on steel surfaces.
Two intelligence groups share similar views on how the fallout from the COVID-19 pandemic has impacted OFS companies’ valuations and operations. What are the impacts of the energy crunch on OCTG demand? Ardyne’s North Sea long-term contracts were for 175 wells with possibly more to follow, while Allseas contract is for removal and disposal for the Valhall complex. The data-driven maintenance program incorporates riser condition, usage, and fatigue analysis with a risk-based inspection process. InterMoor will support Neodrill with project execution, installation services, and business development of its conductor anchor node technology.
McDermott’s completion comes 19 months after it was first awarded. SapuraOMV achieved first production from the Larak gas field in January. Material selection is a first line of defense against corrosion. This article reviews how to recognize pitting and crevice corrosion, as well as how to optimize tubing material selections for marine oil and gas applications based on the material’s PREN value. The methodology is the industry’s first to address CUI.
Approaches to carbon abatement using petroleum are discussed that have a strong chance to succeed in fulfilling technological and economic goals in reducing carbon. The Hydrogen Offshore Production project identifies an alternative to decommissioning by providing reuse options for offshore infrastructure. It aims to prove the feasibility of decentralized hydrogen generation, storage, and distribution solutions to provide a bulk hydrogen solution. Two technologies that may play a part in the decarbonization of the UK energy business are carbon capture, use, and storage and the use of hydrogen as an energy carrier and energy storer. This approach builds on the UK’s gas-network infrastructure, which can be repurposed to avoid becoming stranded.
