Abstract

Workover and well service (WOWS) is a set of operations related to the restoration of production well. On an Onshore Field “Y” there are several wells which currently ineffective in producing oil. Therefore, WOWS is needed to increase oil production. In performing WOWS there are several required systems to support operation such as the hoisting system. Calculating the total weight of the hoisting system requires estimation of vertical weight, horizontal weight, drilling line tension, and the required horsepower to overcome the total weight carried by the rig structure. These elements determine the rig types and draw work specifications. Furthermore, recognizing the hoisting system's ability on holding the WOWS string’s weight. Based on the calculation and analysis, the elements such as vertical weight, etc., are obtained. The calculated vertical weight is around 69,911 lbs., horizontal weight 619.43 lbs., drilling line tension 32,007 lbs., and the minimum required horsepower 297.88 Hp. This parameter sums up the total weight as 134,546 lbs. The results suggest that the rig tower is still safe and operable considering the maximum weight of the structure is double the total operating weight, around 264,554.4 lbs.

Abstract

Well "X" in a West Papuan field is intended to be drilled directionally due to geological constraints that hinder vertically drilling trajectory. The drilling operation required standard deflection tools using bent sub which compensates drilling BUR (Buildup Rate) around 0-3 degrees/100 ft. Four BUR test variations were used in this study: 1.50/100 feet, 20/100 feet, 2,50/100 feet, and 30/100 feet. The maximum inclination angles α0max obtained with a target as deep as 9000 feet and a horizontal deviation of 3500 feet were 30.42, 29,240, 28,620, and 28,230. Out of the four scenarios in this analysis, scenario 4 with a BUR of 30/100 ft was found to be the most ideal due to its shortest length of curve in the buildup portion, after taking into account economic aspects and the drilling time necessary. However, along with the choice of a high inclination angle in a directional well, it can potentially cause technical issues such as high drag force, dogleg severity, cutting buildup, etc.
