HYDPRO
Whether you are drilling a vertical or extended-reach well, an equivalent circulating density (ECD) that is too low or too high can cause serious drilling problems or compromise your project’s budget. A successful drilling operation relies heavily on achieving an optimal ECD. Accurate modeling and optimized drilling hydraulics is crucial. It allows engineers to plan ahead, thus improving drilling efficiencies, reducing risk, and decreasing non-productive time (NPT). Pegasus Vertex's HYDPRO is a comprehensive drilling hydraulics model that covers all aspects of hydraulics, including downhole circulating pressures, surge and swab, ECD, bit optimization, hole cleaning, and volumetric displacements. With these features, downhole drilling hydraulic conditions can be fully examined and any potential problems can be identified prior to field execution.

DEPRO
DEPRO is a comprehensive torque, drag, and hydraulics program. Using this software, users can reduce many of the risks encountered in drilling and completion operations. DEPRO predicts the limits in the length of a horizontal well based on specific friction factors, recommends rig specifications, and evaluates the required weight to set a packer. For hydraulics, DEPRO covers downhole circulating pressures, surge and swab, equivalent circulation densities (ECD), bit optimization, hole cleaning, and volumetric displacements. Using DEPRO, downhole drilling hydraulic conditions can be fully examined and any potential problems can be identified prior to field execution. Torque, drag, and stress calculation. Soft and stiff string models. Drilling, back reaming, rotation off the bottom, tripping in and tripping out operations. Sinusoidal and helical buckling prediction. Field data comparison on workload and surface torque. Friction factor sensitivity analysis. Packer setting analysis.

StuckPipePro
A stuck pipe can result from a wide variety of causes. Typically, these causes are related to mechanical sticking and differential sticking. Mechanical sticking can be caused by key seating, under gauge holes, wellbore instability, poor hole cleaning and related causes. Differential sticking typically occurs when high-contact forces caused by low reservoir pressures, high wellbore pressures, or both, are exerted over a sufficiently large area of the drill string. Stuck pipe occurrences are widely held to be the most expensive drilling problems confronting the petroleum industry and the cost of correcting them can amount to millions of dollars. Running an analysis of well data to predict the stuck chance of a drill string is becoming more imperative.
