![]() ![]() Because the system gives immediate real-time feedback, drilling engineers, wellsite supervisors and superintendents can see if they are deviating from the plan and make corrections based on the system’s guidance.įor this collaboration, the companies are utilizing Pason’s digital infrastructure. "Everybody, regardless of where they are, has a shared understanding of the forward plan, and everyone is informed at each step along the way whether that plan is being executed," Ms Hildebrand added. At the same time, the directional driller – typically working in a remote operations center – and the operator can see the full roadmap and the immediate driller instructions in real time. These instructions are derived from a software-generated “roadmap” for how to achieve a trajectory that meets predetermined steering goals, such as distance to plan and maximum dogleg severity. Specific step-by-step instructions are provided to the driller on a rig floor display. As the well is drilled, the system’s recommendations adapt to changes in the BHA tendency, which can be influenced by factors such as driller sliding skill, bit wear, drilling parameters and formations. "The software continually estimates the current hole bottom position, compares that position to your plan and creates a set of instructions to go from your current hole bottom position to your next steering target," said Ginger Hildebrand, Operational Efficiency Manager – North America Land Drilling at Schlumberger. When employed in drilling a well, the advisor software combines actual downhole and surface data to learn the tendency of the specific bottomhole assembly (BHA) in that well and uses the data to provide real-time feedback and recommendations for drilling the well. Schlumberger emphasized that the algorithms continue to be enhanced and optimized based on suggestions from the field and analysis of every well drilled with the service. To date, more than 250 wells have been analyzed from rigs in a wide range of locations. ![]() Algorithms were then tested and tuned by comparing their predictions to actual performance data. Schlumberger began developing algorithms for the abbl service in 2014 by analyzing data typically acquired when drilling wells in North America. The company said that number could increase as the technology matures and crews build up experience with the system. This means that a single directional driller can monitor operations on multiple rigs at the same time – up to five right now, according to Schlumberger. Both the driller and the directional driller receive immediate feedback on how well those instructions are executed. A rig floor screen conveys these step-by-step steering instructions to the driller. The directional driller, located on or offsite, sees the recommendations and either validates or overrides them. The service uses intelligent algorithms that take real-time downhole and surface data to make steering recommendations. The other is that it allows us to be more consistent." "One is being able to do the exact same work with fewer people on the rig. ![]() “We certainly believe that this offers the possibility of two things,” said Ariel Torre, Senior Vice President of Integrated Drilling Services at Precision. A second well was drilled in July, also in Louisiana, using the same operational model and software. The first well drilled using this service and a reduced crew was drilled in April in Cameron Parish, La., with only one directional driller on the rig. This collaboration is now coming to fruition, resulting in a remote directional drilling service that uses Precision’s drilling rigs and Schlumberger’s abbl drilling operations adviser service. Specifically, the companies Precision Drilling, Schlumberger and Pason Systems - set out to transform directional drilling by increasing repeatable high-quality results while simultaneously reducing the manpower and time required to drill a well. In 2014, launched an initiative with the aim of industrializing unconventional drilling in North America. ![]()
