... (GTI) has explored the interaction of high-power lasers with diverse rock compositions to assess potential drilling applications in the oil and gas sector. A two-year study initiated by GTI aimed to evaluate rock removal capabilities using high-power lasers like MIRACL and COIL, developed by the U.S...

... The general well construction principle is to operate with two defined well barrier envelopes against over-pressured and / or flow potential. Riserless drilling operations do not meet this requirement. The setting of contingency strings prior to entering identified shallow flow hazards has become...

... Abstract A method is proposed to calculate pore pressure at the bit while drilling using all data typically available in a modern drilling operation. This method utilizes a machine learning approach that can estimate pore pressures at the same or lesser range of uncertainty as traditional...

... Abstract The pre-salt reserves offshore from Santos basin represent a great opportunity and probably the most important recent oil discovery in Brazil. These carbonate reservoirs are currently drilled with various types of drill bits, and have proven to be a challenging environment. Since...

... Abstract The objective of the paper is to describe the application of artificial intelligence software to predict formation evaluation logs (compressional sonic, shear sonic and density) using only gamma ray, and resistivity log data and drilling dynamics data as received by the electronic...

... field applications in similarly complex wells. The new model allowed drilling personnel to identify the parameters most likely to induce fractures. Equivalent circulating density (ECD) had the most impact, followed by minimum horizontal stress, Young’s modulus, fracture length, and Poisson’s ratio...

... Abstract Pertamina EP is an Indonesian national oil company which subsidiaries of PT Pertamina (Persero). For nearly 60 years, the Pertamina EP drilling area has been located onshore. In September 2017, Pertamina EP successfully conducted a Poleng N-2 well as the first drilling operation...

... Deep water projects are presently complex, where more drilling challenges can be encountered and higher uncertainty increases the risk of problems during the well construction phase, especially due to the narrow pressure window environments. Managed Pressure Drilling (MPD) is one...
