52 APRIL 2018 WorldWide Drilling Resource ® Advanced Drilling Performance Tools Adapted from Information by Canrig Drilling Technology Ltd. When it comes to drilling, efficiency is important. Canrig Drilling Technology Ltd. offers a line of advanced tools to enhance drilling per-formance. The tools save drilling time and reduce cost by using state-of-the-art technology. ROCKit ® system is a patented directional steering control system. It oscillates drill pipe to reduce friction and increase penetration rate. This reduces drilling time, resulting in huge savings in rig time costs. The ROCKit ® system significantly increases rate of penetration by rocking pipe and delivering ideal weight to the bit. It promotes improved tool face control by allowing fine adjustments while still drilling ahead, reduc- ing the need for lubricants and other friction-reducing addi- tives. Drilling professionals save time by quickly setting tool face orientation. Another drilling performance tool is top drive equipment conditioning monitoring (ECM). Sensors are placed on rig machinery to gather information which determines how well the equipment is performing and when it might be due for maintenance. This information is stored and displayed at the rig site using the company’s RigWatch ® platform, which can be t ransmi t ted and accessed remotely any t ime via myWells.com ® or the RigWatch Pulse ® application for smart- phones. Diesel engine ECM and FuelTool™ is a system comprised of sophisticated hardware, purpose-built software, and web- based data collection. It allows rig site personnel to proactively monitor and efficiently manage engines and fuel consumption. Standard engine management practice requires all engines to operate simultaneously to minimize risk. This practice causes engines to operate at 15-40% load, increasing fuel usage, main- tenance costs, wear at lower loads, downtime risk with extra hours, and overall emissions. By monitoring rig site data, personnel know exactly how many engines are required during rig-up, drilling, logging, cementing, and other phases of well operation. REVit ® technology features advanced top drive automation. It significantly reduces stick slip, a common mode of vibra- tion which limits drilling performance. REVit ® mitigates torsional oscillation in the drill string, and prevents excessive bottom hole assembly and bit acceleration. By precisely adjusting the top drive, revolutions per minute torque waves are absorbed and the stick slip cycle is eliminated. As a result, drilling professionals can extend bit runs, avoid unplanned trips due to bit damage or other downhole tool failures, and increase the rate of penetration, as well as avoid erratic torque and over-torqued connections for significant savings in drilling time and costs. REVit ® system allows the top drive to manage stick slip, enabling drilling professionals to focus on drilling as fast as possible. specifically for oilfield samples. The samples are kept cold during handling and shipping to minimize changes to the DNA. To ensure sample integrity, Biota provides the required materials and training. In addition to field samples, control factors such as drilling muds, frac- turing fluids, and other inputs to the system are collected for quality control. Next, the samples are sequenced using next-generation DNA sequencing technology capable of returning over 10,000 reads per sample, providing highly specific information to identify the subtle subsurface changes which impact busi- ness decisions. After sequencing, the data is thoroughly checked to remove any sequences introduced to the sample by human and environmental contamina- tion, ensuring the highest Subsurface DNA signal accuracy. Most Subsurface DNA is obtained from microbes living in fractures, faults, and large interparticle pores. Microbes are very small and can live in the pores of minerals and organic matter; however, the majority of microbial communities are thought to be living in fracture pores, which are pore spaces formed through faults, fractures, and joints, providing sufficient space for microbial communities to survive.
