Well Design

We design sidetracks using Landmark (COMPASS™), the best-in-class software for directional drilling design, measurement control, plotting and well-collision avoidance. Our engineers can accomplish the following through the application of integrated technologies: ~ engineering studies and BHA selection, predicting BHA performance in specific geological environment; ~ prediction and analysis of loads, moments and friction coefficients for drill strings and casing strings during downhole operations; ~hydraulic calculation of parameters for drilling and openhole reaming; ~modeling of pressure surges caused by drill string or casing string movement in adverse downhole environment, design of drilling and tripping hydraulics; ~stuck pipe release analysis and design; ~cementing design, detection of possible problems, adjustments to the cementing process.
