Modeling of Swab and Surge Pressures: A Survey
Mohammad, Amir; Davidrajuh, Reggie (Peer reviewed; Journal article, 2022-03)Swab and surge pressure fluctuations are decisive during drilling for oil. The axial movement of the pipe in the wellbore causes pressure fluctuations in wellbore fluid; these pressure fluctuations can be either positive ... -
New Simple Analytical Surge/Swab Pressure Model for Power-Law and Modified Yield-Power-Law Fluid in Concentric/Eccentric Geometry
Mohammad, Amir; Agonafir, Mesfin Belayneh (Peer reviewed; Journal article, 2023)The axial movement of pipe in and out of the well generates positive (surge) and negative (swab) pressures that will impact the well pressure. When the swab and surge effects cause well pressures outside the allowable ... -
Physics-Based Swab and Surge Simulations and the Machine Learning Modeling of Field Telemetry Swab Datasets
Mohammad, Amir; Agonafir, Mesfin Belayneh; Davidrajuh, Reggie (Peer reviewed; Journal article, 2023)Drilling operations are the major cost factor for the oil industry. Appropriately designed operations are essential for successful drilling. Optimized drilling operations also enhance drilling performance and reduce drilling ... -
Prediksjon av trykk i brønner under boreoperasjoner ved bruk av maskinlæringsteknikker
Grindalen, Jonas; Krøyer, Vebjørn Njåtun (Master thesis, 2023)Denne avhandlingen undersøker bruken av maskinlæring (ML)-algoritmer for prediksjon av trykkstigning og trykksenkning under boring i olje- og gassektoren. Disse trykkene er avgjørende for å opprettholde brønnstabilitet og ... -
Rate of Penetration (ROP) Optimization through Data-Driven Approach
Adnan, Isar (Master thesis, 2023)One method to lower cost and Non-Productive Time (NPT) in drilling wells is to achieve the highest rate of penetration (ROP). ROP is influenced by a variety of factors, including tooth attrition and hole cleaning. Three ...
