WELLPLAN™ Torque and Drag Analysis Software
We are pleased to announce the launch of our new Landmark website. You will be redirected to the new location shortly.
Description | Features | System Requirements
Plan and analyze drilling and casing running operations and assess the impact of predicted loads related to torque and drag.
To ensure successful drilling operations, especially in today’s complex wells, it’s crucial to have adequate knowledge of the anticipated loads for drilling and casing operations. Landmark’s WELLPLAN™ Torque and Drag Analysis program provides this critical information.
WELLPLAN™ Torque and Drag Analysis software allows users to identify potential problems during planning and supplies standoff devices, casing flotation optimization and other tools to investigate design modifications for improvement.
In addition, engineers can determine if the selected rig has adequate mechanical specifications to handle well design requirements. The application allows users to stream real-time actual load information into WELLPLAN™, analyze planned versus actual loads, and simulate the effects of different mud types or lubricants.
WELLPLAN Torque and Drag Analysis software is deployed on Landmark’s Engineer’s Data Model™ (EDM), the platform for a fully integrated suite of well engineering and data analysis applications. EDM provides one-time data entry, a system to promote best practices, and an environment for managing and accessing operational knowledge and lessons learned.
Benefits
Effective torque and drag analysis
Performing powerful torque and drag analyses during the design and operations phase of a well requires minimal effort and produces excellent benefits.
Quicker decision-making
Engineers can easily study the effects of different operational parameters along with string and wellbore configurations to determine the best solution for a given design objective. Integration with COMPASS™ on EDM™ technology enables users to make better decisions, faster.
Versatility
This versatile application enables users to meet all well design requirements of downhole tool companies, services companies, and operators.
Rapid engineering studies via OpenWells™
Integration with Landmark’s OpenWells™ rig site data collection and reporting system enables engineers to directly create a WELLPLAN™ case, automatically populate the case with pertinent field and rig data, then use the information to rapidly undertake engineering studies.
Optimized workflows
“Plug and play” compatibility across the WELLPLAN suite and with other EDM applications enables comprehensive engineering workflows from a single application. The result is an optimized engineering environment and enhanced efficiency.
Features
Integration with other EDM applications
Common data navigation with other EDM applications using the Well Explorer. EDM allows sharing of directional profiles with wells created in COMPASS, Landmark's industry leading directional planning application.
Standalone or multi-user environment
Operates in a standalone or in a fully concurrent multi-user network environment with powerful user management and data locking features. Built to scale from a single user application to a corporate engineering system.
Drag Sensitivity Plot
A new Drag Sensitivity Plot has been added for quick analysis of actual load data or to assess risk across a range of friction factors for cased and open hole.
Real time data analysis
Actual Load Data, surface loads and torque can be loaded real time from a WITSML provider. This information can be compared to plan data to quickly determine downhole related problems
Documented reliability
Field-test cases have documented the reliability of the tool, which calculates coefficient of friction and variable coefficients of friction along the Wellbore.
Comparative design analysis
The engineer can easily study the effects of different string and wellbore configurations to determine the best solution to meet design objectives. The COMPASS program can be used to design several acceptable well paths to reach the specified targets, and with the powerful integration afforded by EDM the user can quickly analyze the impact of each.
Industry standard and Landmark enhanced algorithms
Computes hook-load and rotary torque for rig and drill string design, and determines critical buckling forces using Lubinski and Paslay-Bogy equations.
Tri-axial analysis
Axial forces, neutral point, and torque along the drill string can be calculated, and the tool predicts contact forces along the string in a 3D wellbore. Computes equivalent Von Mises Stress and compares it to yield stress (API RP7G).
Five operation modes
Five operational modes are accommodated: rotary drilling, drilling with a motor, tripping in, tripping out, and rotating off bottom. Drag charts covering these modes are compiled.
Multiple applications
Can be used for casing and liner analysis and to determine rotary torque, measured weight, pick-up and slack-off, string windup (with and without bit torque), and stretch for all points along string for the five operational modes.
Applicable to coil tubing operations
Using Top-Down Analysis to analyze coiled tubing operations. In this mode the known injector forces at the surface can be specified. A tension or compressive injector force at the surface can be specified. The calculation starts from top and calculates forces acting on the tubing downhole.
Casing Flotation Optimization
Automatically determines the optimum length of air column to minimize drag forces allowing casing/liner to be run to TD. Alternatively, given a fixed air column length, the maximum depth the casing/liner can be run will be computed.
