PPSC – Wellbore Trajectory
PPSC – Wellbore Trajectory accepts survey data such as inclination angle, measured depth, and azimuth to plot 2D and 3D wellbore trajectory. Users can plot multiple wellbore trajectories in the same field to study potential collision of new infill wells.
PPSC – Production
PPSC – Production allows users to design and optimize an oil and gas production system. Its friendly user interface allows users to easily and quickly upload data, design a complicated wellbore, or choose proper models and correlations for a specific application, etc. Users can then do the nodal analysis to optimize tubing sizes and production rate. Sensitivity analysis can be performed easily to provide users a better understanding of the production system’s performance . In addition, PPSC – Production provides or handles the following:
- Analysis of IPR and OPR to obtain current and future production rates. Users can carry out thorough nodal analysis to optimize a production system.
- Simulate actual production conditions with a specific artificial lift method such as EPS, rod pump, gas lift, plunger lift, and PCP.
- Design for injection wells such as water disposal injection, EOR injection, and CO2 injection. Maximum anticipated surface pressure during these operations can be estimated.
- Predict bottomhole pressures using tubing head pressures and production data. In addition, this software is capable of predicting bottomhole pressure of wells that have artificial lift methods such as EPS, gas lift, and rod pump.
- Plot pressure profile (pressure traverse) of production fluid in a production tubing using existing multiphase flow models such as Beggs and Brills, Zhao, Hagedorn and Brown, Duns and Ros, etc. The effects of temperature, reservoir fluid properties, tubing size, etc. are taken into consideration to estimate the multiphase flow patterns and flow regimes and hence to accurately estimate the pressure drop in a production system.
PPSC – Heat Transfer
PPSC – Heat Transfer allows users:
- To get fluid temperature profile along with production tubing.
- To obtain temperature profile inside the drill pipe and annulus during drilling operations.
- To simulate heat transfer under different scenarios during geothermal drilling operations and geothermal production operations.
PPSC – Casing and Tubing
PPSC-CT allows users to design and select casing and tubing in oil and gas wells. Users are able to manually enter the wellbore diagram or to automatically upload wellbore survey data. The software then automatically recommends casing setting depths and calculates critical loads for each selected casing. The worst case scenarios under operating conditions for burst and collapse pressures can be performed to study the integrity of the selected casing or tubing. Tri-axial stress analysis is used to obtain the critical stress conditions of each casing and tubing. PPSC-CT also provides the following:
- Drag, torque, and buckling analysis.
- Maximum anticipated hook load.
- Maximum anticipated derrick load.
- Annular buildup pressure.
- Wellhead growth analysis.
PPSC – Drilling Hydraulics
PPSC – Drilling Hydraulics can be used to correctly predict the hydraulics during drilling operations which is one of the most important tasks to successfully drill an oil and gas well. Drilling fluids are very non-Newtonian behavior and constantly subjected to changes under different pressure and temperature conditions. Therefore, estimating hydrostatic pressure and frictional pressure losses in pipes and annuli are not an easy task. In addition, drilling extended reach wells with lateral lengths from 1 – 4 miles have become a norm in the oil and gas industry. Multiple challenges have occurred when drilling long lateral sections such as severe friction losses, high drag and torque, very high ECD, high pump pressures and horsepower. This software allows users to design and optimize the hydraulic system during drilling operations. PPSC – Drilling Hydraulics provides the following but not limited to:
- Design Equivalent Density (ED) and Equivalent Circulating Density (ECD) of drilling fluids for each casing hole.
- Maintain good hole cleaning by recommending sufficient jet impact force, annular velocity, and fluid properties such as yield stress, Bingham plastic viscosity.
- Prevent barite sag.
- Take the cutting bed height in the lateral section (two or three lay model) into consideration when calculating ECD.
- Maximum anticipated pump pressure and pump horsepower.
PPSC – Artificial Lift
An appropriate Artificial Lift (AL) method is a guarantee of efficient production during the life of wells. There are many factors that need to be considered when selecting an AL method for a particular well and a particular reservoir. In addition, with the boom in horizontal drilling and hydraulic fracturing for unconventional reservoirs, selecting correctly artificial lift methods to maximize the production of horizontal wells are so critical in recent years. PPSC – Artificial Methods allows users but not limited to:
- Design and optimize thoroughly a production system of a specific lift method such as ESP, gas lift, rod pump, plunger lift and PCP. Multiphase flow modeling incorporated in the production tubing, PVT of formation fluid, temperature, and well stimulations.
- Quickly screen/select artificial lift method(s) applicable for a specific well and a specific reservoir condition. Users are allowed to handle unconventional reservoirs such as heavy oil, tight gas/oil reservoirs, and shale formations. Hydraulic fracturing is also considered while a lift method is selected.
- Get a recommended list of available surface and subsurface equipment for each design using the software’s data bank.
- Optimize the operating conditions to maximize the productions.
