Paper presented at the Offshore Technology Conference Brasil, October 24–26, 2023
Paper Number: OTC-32866-MS
... Abstract Most drill pipe failures are caused by metal fatigue because of repeated or fluctuating stress. The cumulative damage rule and S-N curves are used in a tool to calculate the amount of fatigue life consumed in drill strings. Comparisons are performed between the stress methodologies...

... Seismic attribute calculations have been traditionally used for measuring specific traits in seismic data for further interpretation ( Chopra and Marfurt 2007 ). These calculations tend to have a fixed operator or window size from one sample to the other during the computation. They also tend...

... be as low as 5 or higher than 7. The pH calculations showed that to achieve the lowest pH, it is necessary to remove the most of water on the first three-phase separator. The first separator has the highest pressure (20 barg) and high CO 2 content which leads to lower pHs due to water – CO 2 equilibrium...
