When we talk about the “Application of the operating principies of the integrated Landmark software for the calculation of operating limits in 550 HP drilling rigs in the Peruvian Northwest”, we are referrIng specifically to the calculation of the máximum depth as far as we can Actívate the drill jar when we drill with these 550 HP hydraulic Rig, which feature Top drive and drill with 5 inch OD drill pipes. The 550 HP Hydraulic Drilling Rigs have a maximum nominal lift capacity of 100 TN (220 klbs), which are used for drilling shallow wells of 3,000 ft and other times for intermediate wells of 5,500 ft in the Northeast. Peruvian. We must keep in mind that, if the nominal capacity of these drills is 220 klbs and their safety factor is 15%, we could safely tension the drill up to a maximum of 187 klbs upwards, but in practice it will be tensioned up to a maximum of 200 klbs. From what has been seen, these 550 HP hydraulic drilling rigs, with top drive and 5” drill pipe, do manage to drill up to 5,500 ft MD depth or even more, but under normal conditions, as long as they do not there are no sticking events nor the need to use the drilling jar, since for its activation at these depths (5500 ft MD) load tensions in the Martin Decker greater than 200 klbs are required. In addition to trying, we would be putting at risk the structures and substructures of the drill, even an entire drilling project. Therefore, the maximum lifting capacity of the Equipment (Block Rating) will determine whether the activation of the Jar drilling is possible in the event of pipe sticking, since such a load tension force is necessary for its activation. that can overcome the weight of the string plus the drag generated, and if this tension force necessary to activate the jar exceeds the maximum capacity of the drill, then we simply will not be able to activate the jar and we will be left without any type of contingency nor will we have the possibility not even hammering and recovering the directional BHA. Based on our experience drilling directional wells in northwestern Peru, when we drill with these 550 HP drills (with low lifting capacity) and we have the need to use the hammer, we will be able to hammer only up to a certain depth, which could vary between 3,600 to 5,000 ft MD depending on well type, trajectory, inclination, DLS and tortuosity levels generated. Therefore, to drill with these 550 HP drills, it is necessary to have the knowledge of exactly how deep we can activate the drilling jar, and to be sure that up to said depth we can at least try to recover the directional tools that are found. trapped at the bottom of the well. We can calculate this maximum activation depth of the Jar based on our methodology with Landmark's Well Plan software, which we present in this project as “Application of the operating principies of Landmark's integrated software for calculating operational limits in 550 HP drilling rigs in Northwest Peru”. It must also be considered that in the North West of Peru there are loss of circulation formations such as Hélico, Cabo Blanco, Echinocyamus that also complicate the operational development of drilling and can even generate collapses that lead to mechanical failure, as well as depleted areas that lead to differential problems.
