Geology

In this module a geomechanical model using well logs data and empirical Correlations is built. Geomechanical model is used for introducing a safe mud window and recommend safe and stable drilling trajectory. The casing program and shoe depths are determined by the pore pressure profile obtained from the geomechanical model.

Rig Selection

In the rig selection module, rig type and the related components such as power system, traveling block, and so others are selected based on the field and operator needs.

Drill String Design

Drill string modeling includes designing a drill string, considering vibration and friction factor between the drill string and the annulus is. There are some other important outputs such as tension graph, optimum placement of drill string components, and optimum RPM.

Mud Design

Drilling fluid program is divided into three subtopics: studying drilling fluid contents, solid control equipment, and waste management. Exports of high importance are: designed and enhanced drilling fluid according to the formation, solid control equipment optimization, and waste management efficient program.

Bit Design

This module has two parts of bit and hydraulics design. Bit design can help us to select an optimum bit profile based on formation characterization. Hydraulics design provides bit hydraulics optimization, determination of the minimum flow rate for hole cleaning, and the maximum flow rate to avoid turbulent flow, and distinguish probable stuck depths.

Drilling Progress

This module consists of four general sections: providing the risk level of each depth, operations sequence of each hole, determining critical speeds of surge and swab, and controlling data from MWD and the drilled trajectory against the predicted trajectory.

Well Control

This module covers all the calculations needed to control the well before kick occurrence such as the maximum influx volume and during kick occurrence such as preparing the kill sheet and presenting the well killing program. This module can also be used to select and arrange BOPs in BOP stack and carry out accumulator calculations.

UnderBalanced Drilling

This module calculates and simulates all properties of implementation of the underbalanced drilling operation. Another feature of this module is to study drilling operation based on online field data. Pressure profile along with the well, fluid flow properties, cutting removal phenomena, and hole cleaning are the outputs of this module.

Directional Drilling

This module consists of two main parts, including survey calculation and well planning. These parts enable the user to calculate the well trajectory using different types of survey calculation methods, design and plan different types of wells, respectively. Also, horizontal and vertical view, planned well trajectory and drilled well trajectory are some of the outputs of this modulus.

Casing Design

In this module, considering the probable scenarios of burst, collapse, axial loading and external pressure profiles in the well and the surrounding area, the highest stresses on the casings are determined in each part of the well. The optimum casing for each section is designed, and the body and its joints grades are determined.

Cementing

This module analyzes and designs cementing operation in four distinct parts: volumetric cement calculations, hydraulic calculations of the cement and displacing fluids pumping into the wellbore, design of the centralizer placement scheme and calculation of the depth of different fluids placement in the wellbore. Graph of the ECD versus depth, depth of the top of cement, optimum pumping rate, and centralizers spacing are some of the important outputs of this module.

Well Test

Operating procedures and tool specifications of well tests such as drill stem, injectivity, buildup, drawdown, interference, and so others are the outputs of this module.

Well Logging

This module consists of two main sections: well logging and perforation. Important outputs of the well logging section include show reservoir logs, Evaluation of net reservoir thickness, lithology of the formation and water saturation. The perforation section can also determine the fluid type, flow rate, pressure and temperature, and the appropriate perforation conditions.

Fishing

This modulus is a guide in selecting fishing tools according to pipe stuck in the borehole. The proper type of jar is suggested along with other outputs.

Well Head

This module can be used to design tubing and surface equipment of a well after drilling. Well diameter, type of producing fluid (crude oil or gas), and the reservoir depth are the most critical inputs data; and tubing size and its components, type of surface equipment, packer selecting are some of the important outputs of this module.

Stuck Pipe

This module helps to find pipe sticking mechanisms and proposes proper solutions such as jarring, fishing, and chemical injection to this problem. Forces and Tensions on drill string are modeled to decide on the amount of Overpull or slackoff to free the pipe at the point of stuck.

DETAILS BACK

Acidizing

Aim of this module is acidizing procedure design. Based on reservoir type, acid volume in three stages must be calculated. Recognition acid type, acid propagation in the reservoir, maximum allowable surface pressure, and formation response by plotting skin versus acid volume or time are the outputs of this module.

DETAILS BACK

Production

This module calculates the pressure drop in the surface pipelines and wells, and the production rate of the wells will be reported in different operating conditions. There is also a study of the pumps and the optimum depth of their installation in the well. Among the other outputs of this module can be specified the optimum operating conditions of the separators and the maximum flow rate to prevent the coning phenomenon.

Well Cost

This module considers costs of different parts of drilling operation like, personnel's salary, rig up and rig down operations, preparing roads and location, rig rent, rig services, equipment, directional drilling, etc.

DETAILS BACK

3D View

This module contains three main subdirectories of plot 3D view, Anti-Collision analysis and, well trajectory correction. These parts enable the user to plot the 3D view of the planned or actual well path, preventing designed well to collide with adjacent wells and, correct the well trajectory which deviated from the main path, respectively. The main outputs are spider plot, ladder view, and traveling cylinder plot.
