AUTOMATED PATTERN RECOGNITION IN REAL-TIME DRILLING DATA FOR EARLY KARST DETECTION
Maksimov, Danil; Løken, Marius Alexander; Pavlov, Alexey; Sangesland, Sigbjørn (Chapter, 2021)Drilling in carbonate formations often poses a real challenge to operators, contractors and service companies. Severe fluid losses, gas kicks and other unwanted situations increase drilling risks. These risks are closely ... -
Drilling in Karstified Carbonates: Early Risk Detection Technique
Maksimov, Danil; Pavlov, Alexey; Sangesland, Sigbjørn (Peer reviewed; Journal article, 2020)Heterogeneous nature and complex rock properties of carbonate reservoirs makes the drilling process challenging. One of these challenges is uncontrolled mud loss. Caves or a system of cavities could be a high-risk zone for ... -
Prediction and early detection of karsts for safer drilling in carbonates
Maksimov, Danil (Doctoral theses at NTNU;2022:108, Doctoral thesis, 2022)Underestimation of drilling hazards in carbonates can lead to serious consequences to personnel and the environment. The history of drilling in carbonates has shown that the vast majority of drilling incidents are associated ... -
Prediction and Early Detection of Karsts — An Overview of Methods and Technologies for Safer Drilling in Carbonates
Maksimov, Danil; Pavlov, Alexey; Sangesland, Sigbjørn (Peer reviewed; Journal article, 2021)The nature of carbonate deposition as well as diagenetic processes can cause the development of unique geological features such as cavities, vugs and fractures. These are called karsts. Encountering karsts while drilling ... -
Real-Time Detection of Karstification Hazards While Drilling in Carbonates †
Maksimov, Danil; Pavlov, Alexey; Sangesland, Sigbjørn (Peer reviewed; Journal article, 2022)The nature of carbonate deposition can cause the development of unique geological features such as cavities and vugs called karsts. Encountering karsts while drilling can lead to serious consequences. To improve drilling ...
