Well Planning

Providing the client with a drillable well design that meets their requirements is always the main goal of our well planning engineers. This is achieved by close collaboration with our clients to fine-tune a well profile.

Well Guidance uses Landmark’s COMPASS™ directional well planning software, which is the industry’s premier application, for directional planning, survey data management, and anti-collision analysis. This together with Landmark’s WELLPLAN™ software allows Well Guidance to provide high level well planning services which conform to ISO quality standards.

Our engineers provide technical support in design, planning, and monitoring wellbore proximity

We use Compass software to design 2-D drawings that have a common reference to illustrate a designed wellbore trajectory.

Plan the most accurate and cost effective directional survey program to ensure wellbore placement within the drilling targets. Our well planners can provide planning for any type of well.

Reduce drilling risk by minimizing the possibility of collision using wellbore positional uncertainty incorporated into the anticollision analysis

Torque & Drag analysis system is used to validate well designs and prevent loss of rig time by eliminating drilling string failure. Our engineers can use the system to model all types of BHAs. Plan and analyze drilling, casing, and completion running operations, and assess the impact of predicted loads related to torque and drag. The main calculations are tension, torque, side force, fatigue, and tri-axial stress. A top-down analysis mode uses surface parameters to accurately understand forces acting along the string to the bottom of the well. It also accounts for the effect of hydraulic parameters such as fluid properties, flow rates, diverse fluid columns and pressures. Temperature effects on the string also are considered for pipe stretch calculations. Riserless and inner-string configurations are modeled, as well as the effect of stand-off devices such as centralizers and friction reducers. Soft, stiff or hybrid string models can be used for the analysis.Soft and stiff string analysis options allow calculation of all the forces acting upon the BHA including torque, drag, stresses and side forces. The calculated loads are compared to string yield limits and rig operating limits and the results presented for fast identification of specific issues. Detailed graphical and tabular results provide a comprehensive description of the modeled scenario. Multiple user defined operating modes can be incorporated in a single calculation, allowing the entire drilling process to be modeled for a given hole section.

This module can be used to model pressure losses across the rig’s circulating system and pipe-string, estimate equivalent circulating density (ECD) across the annular space, and analyze formation cuttings transport and its effect on pressure and ECD calculations. Temperature effect is also considered using four different rheological models, fluid compressibility, Fann® Viscometer readings at different temperature points, critical fluid velocity, and bit-nozzle size calculations for optimized rate of penetration. The module considers string eccentricity effect, pipe roughness, returns to sea floor for dualgradient operations and backpressure for underbalanced operations.
