Typical Equipment Activity Name: Soft Soil Investigations (Auger drilling) Activity Number: Date Prepared: 04/01/2009 Safety Boots, Hardhat, Reflectorized Vest, Safety The practice of directional drilling traces its roots to the 1920s, when basic wellbore surveying methods were introduced. Before drilling begins, the following safety precautions should be in place. Necessary cookies are absolutely essential for the website to function properly. View Sitemap. Drilling crews are required to follow a Job Safety Analysis (JSA) procedure which Directional Horizontal Drilling has expanded to total job analysis and is reviewed each day crews are on site. Mud motors generate angle by sliding. Picture 1 of 8. HDD may be used where traditional vertical excavations are too hazardous, at sites with limited space, like dense, urban areas, and in industrial and residential areas. Thanks for the interesting article about directional drilling. Post Hole Digging. Buried cables may not have been installed in a straight line and excess cable loops are often buried. It seems there are quite a few methods and techniques being used by engineers and it is quite interesting. . To achieve our safety compliance goals, dedicated staff members are assigned to ensure internal safety procedures are followed. Horizontal Directional Drilling (HDD) is a trenchless technology that uses surface-launched equipment to drill underground horizontally and install pipes, conduits, and cables. The first modern, reliable and costly effective downhole drilling mud motors was designed and manufactured in 1958 by the Dyna-Drill company. When all of the data from the drill bit, collars, motors and the surface equipment enter the control panel, a complete representation occurs. Companies Mentioned. CWB spesialis jasa pengeboran khusus dengan mesin HDD ( Horizontal Direction Drilling ). If identified during planning, the best approach is to avoid the obstacle. Horizontal drills also make it possible to bypass obstacles, like roads and rivers, by boring . From the safety perspective, no method is perfect. The gyro is heavier than a magnetic steering tool and is housed in a large, steel sub, approximately 8.5 ft in length and weighs up to 1,200 lbs. Drill bit sensors can tell the driller about external weight, and rotary speed that can also be used to influence the trajectory. If unexpected or inconsistent readings are encountered, stop drilling. Students of petroleum engineering often get shown illustrations and diagrams that look like tree roots. A water line? Its possible for ERD specialists to drill for more than 10 kilometers/6.2 miles.

Download this free report today and get inspired to improve your workplace safety program! Current expenditures for hydrocarbon production have dictated the necessity of controlled directional drilling to a much larger extent than previously. Download Free PDF Related Papers Over the past few decades, technological improvements have meant that angles, turns and underground distances covered are amazing feats of engineering. Techniques such as multilateral, horizontal and extended reach drilling (ERD) are enhanced oil recovery (EOR) methods that can increase the yield of a downhole dramatically. Pulling the reamer or product pipe through the bore hole too rapidly can also result in a surface heave. A whipstock is a type of wedge that can redirect the drill. Necessary cookies are absolutely essential for the website to function properly. Horizontal directional drilling can be used for smaller-scale purposes such as installing utility cables or pipelines and is quickly becoming a popular alternative to the trenching method, which involves digging or cutting up the ground. Debris and spoil: Directional boring operations can generate large amounts of spoil and debris which can disrupt surface features and contaminate groundwater. Human Error: Operator error can lead to incorrect boring trajectories, and may result in significant delays and cost overruns. Safe drilling requires good planning.

We require employees to actively participate in internal safety training and service programs relevant to their employment and complete any training programs required by law or relevant to the specific project. A good best practice is to have someone familiar with the job directly observing and recording the series of individual tasks as an experienced employee performs them. More time can be spent drilling, and less time removing the drill bit and conventional whipstock. Since the motor that turns the drill is at the surface, how can the drill string continue to rotate at 360 degrees while going around a corner? Ground heave and subsidence: Directional boring can cause ground heave and subsidence due to the disturbance of the soil. In a vertical drilling application, such as water well drilling, the annular ascending velocity of drilling fluid is somewhere between 85 feet to 125 feet per minute, in comparison to horizontal directional drilling where fluid moves at a snail's pace due to larger-diameter boreholes and the direction of flow. Continue reading here: Calculating the Installation Stresses. Under Road Boring.
