Practical Drilling Skills - PDS - In House Training

Practical Drilling Skills - In-house training by PetroSkillsThis course can be conducted on site at your location exclusively for your staff. This course was developed by a major operator as an 'on-site' drilling school. Experienced rig supervisors and drilling engineers spent a week at a drilling rig [Friday to Friday, 7:30am until 10:00PM] in intensive application of class room discussions. This course takes that learning and brings it back to the classroom. The techniques will be presented in such a manner that participants should be able to immediately apply the technology upon returning to the drilling rig.Computers do a wonderful job of calculating numbers if equations are correct and the input data is available. Unfortunately, many variables associated with drilling rigs remain unknown and not predictable. This course teaches how to listen to the well, perform simple tests on the rig, and make proper decisions unique to each well.The overbalanced pressure at the bottom of a borehole controls many aspects of drilling. A mud logger's gas units can reveal much information but is usually not understood. The mud logger's gas unit curve can be calibrated to reveal how much gas is in the drilling fluid. The flow in the drill string and annulus is partially laminar and partially turbulent depending greatly upon the flow rate and the rheological properties of the drilling fluid. This controls the nozzle sizes required to cause the drilling fluid to strike the bottom of the hole with the greatest force or greatest power. Unfortunately, this flow regime cannot be predicted prior to drilling. A procedure is presented which allows proper nozzle sizes to be installed in the drill bit and determine the correct optimum flow rate. The correct yield point can then be predicted which will lift cuttings through the vertical part of a well bore. When the new bit with the correct nozzles returns to drilling, the flounder point of either a roller cone bit or a PDC...
