... Abstract SPE's Drilling Systems Automation Technical Section (DSATS) sponsors the Drillbotics® autonomous drilling contest to promote advanced learning at participating universities. Two groups working independently employed similar engineering, software, and control technology to detect...

... ABSTRACT High-temperature geothermal resources away from tectonic boundaries or geologic hotspots can be accessed by the drilling of deep wells through significant sections of basement rock. This paper evaluates the impact of rapid cooling on rock cutting process, and incorporates this effect...

A digital workflow is set up from pre-drill 3D basin scale pore pressure modelling using a stochastic Monte-Carlo approach, including an automated update of pressure...

... minimizing drilling costs and safety risks. Directional surveys that have minimal uncertainty are crucial to drilling the optimized well plan. This work enables more accurate directional surveys and wellbore placement through site-specific high accuracy magnetic models. Under the Industry Steering Committee...

... Abstract The drilling industry has undergone significant changes in recent years, leading to increased efficiency, lower costs, and reduced emissions per production unit. As unconventional well construction complexity continues to increase, the next wave of innovation lies in process automation...

... Abstract This paper presents an autonomous drilling advisory system powered by digital twins and AI solutions. Such an advisory system aims to automate real-time monitoring and parameter optimization, reduce subject-matter experts, and meet the demands for safer and more efficient drilling...

... Abstract Drilling operations in the US Permian Basin shale play with a new 4-¾" Rotary-Steerable Drilling System (RSS) revealed that with high Rates Of Penetration (ROP), high Weight On Bit (WOB) (and other drilling parameters) encountering stringers or interbedded formations can lead...

... of geothermal – that would enable geothermal drilling and production in most places in the world – is hard rock or superhot rock concepts. Developing these systems requires drilling into granitic basement formations, often at temperatures exceeding 300º C. There are two main technological challenges associated...

... Abstract Over the years, some researchers have used Mechanical Specific Energy (MSE), which is said to represent the amount of energy needed to drill a unit volume of rock, to quantify drilling efficiency. MSE was originally introduced by Teal for the mining industry in 1964. Since then, MSE...

... Abstract Managing drilling dysfunction is key to safely drilling horizontal wells in harsh environments. However, extended horizontal wells with long open-hole intervals complicate identifying and addressing dynamic drilling problems using surface measurements. The latest generation downhole...

... Abstract This paper investigates the drill pipe twist-offs that occurred while drilling an S-shaped well in the 12 ¼" section. The presence of the 2nd mode shape of torsional vibration was observed and linked to the failure. Conditions that lead to a 2nd mode shape being triggered and sustained...

... One of the classical approaches to approximate an optimal combination of drilling parameters is a drill-off test. During a drill-off test, a steady high WOB is applied and the drawworks is locked. The circulation and rotation are continued such that bit penetration is provided by an increasing...

... During riserless drilling the options for maintaining well control once a shallow flow occurs are restricted (during both riserless drilling and drilling with a riser plus diverter system). Pilot hole drilling is accepted as a mitigation technique to identify shallow gas within a "managed...

... Prior to entering the Travis Peak, drilling can proceed at a fast rate without a high risk of drilling dysfunction. An ideal drilling program takes advantage of the fast drilling and transitions into the DOCC method of drilling with a "just in time" approach. To help guide the driller on how...

... Abstract As part of the digitalization and utilization of Automated Monitoring during drilling operations, real-time dynamic modelling of downhole combined with 3D dynamic visualization have been implemented on the drillfloor in offshore rigs. The objectives have been to give the driller...
