Cuttings-Bed Erosion in Horizontal Wells: Biopolymers Impact and its Rheological Dependence
Mirzaei, Mohsen; Paso, Kristofer Gunnar; Saasen, Arild (Journal article, 2023)Efficient wellbore cleaning in highly deviated and horizontal wells is a challenge, as there are large areas where the cuttings tend to be deposited. Insufficient wellbore cleaning could cause major operational problems ... -
Effect of Hydrophobic Iron Oxide Nanoparticles on the Properties of Oil-Based Drilling Fluid
Alvi, Muhammad Awais Ashfaq; Belayneh, Mesfin; Fjelde, Kjell Kåre; Saasen, Arild; Bandyopadhyay, Sulalit (Peer reviewed; Journal article, 2020)Lately, nanoparticles (NPs) have shown the potential to improve the performance of oil well fluids significantly. Several studies have reported the ability of NPs to produce improved properties of both water and oil-based ... -
Experimental Bench-Scale Study on Cuttings-Bed Erosion in Horizontal Wells
Pedrosa Consicion, Herman Camilo; Lund, Bjørnar; Opedal, Nils van der Tuuk; Ytrehus, Jan David; Saasen, Arild (Peer reviewed; Journal article, 2022)Cuttings-beds formation while drilling wellbores is a common challenge, especially for horizontal wells, as drilled particles have higher area to be deposited and form cuttings-beds, which can cause several problems such ... -
The fate of hydrocarbon leaks from plugged and abandoned wells by means of natural seepages
Tveit, Mari Røstvig; Khalifeh, Mahmoud; Nordam, Tor; Saasen, Arild (Peer reviewed; Journal article, 2020)When a well reaches the end of its productive life, it is permanently plugged and abandoned. Even though new technology and verification methods are being evaluated, it is evident that operational, barrier material and ... -
Fundamentals and physical principles for drilled cuttings transport – Cuttings bed sedimentation and erosion
Pedrosa, Camilo; Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)The increasing necessity of challenging wellbore structures and drilling optimization for improved hole cuttings cleaning has been growing along time. As a result, operator companies have been researching and applying ... -
Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition
Pedrosa, Camilo; Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2022)Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ... -
Measuring filter-cake cohesive strength and flowability
Klungtvedt, Karl Ronny; Pedrosa, Camilo; Saasen, Arild (Peer reviewed; Journal article, 2022)The filter-cake has a critical role in temporarily reducing the permeability of the wellbore to prevent issues such as lost circulation, formation damage, wellbore collapse and differential sticking. The filter-cake's ... -
Properties of Dense Barite Sediments from Water-Based Drilling Fluids Oscillatory Viscosity Measurements of Wet Barite Powder
Werner, Benjamin; Pedrosa, Camilo; Skorpa, Ragnhild; Ytrehus, Jan David; Vrålstad, Torbjørn; Saasen, Arild (Journal article; Peer reviewed, 2021) -
Wet Drilled Cuttings Bed Rheology
Pedrosa, Camilo; Saasen, Arild; Lund, Bjørnar; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ... -
Wet-granular rheology to measure cuttings-bed strength
Pedrosa, Camilo; Ytrehus, Jan David; Aschl, Timothy; Lund, Bjørnar; Saasen, Arild (Journal article; Peer reviewed, 2021)
