An oilfield drilling system is a complex collection of many individual elements including the drilling rig, surface drilling equipment, the drill bit, the bottom hole assembly (incorporating a combination of often very sophisticated tools with electronics and complex mechanical components) and the drill string. The performance of even the most advanced drilling rig and a complex steerable BHA with a full suite of MWD and LWD tools can be compromised by a lack of attention to maintaining drill string integrity. Drilling tubulars represent a substantial part of the total capital equipment needed to drill a well, and proper maintenance and repair is essential to avoid the high unplanned costs associated with drill string failure.rnHigh quality tubular repair services actually begin before the component ever sees the machine shop floor. At SMITH, the first step is for a qualified representative to meet with the customer to discuss the scope of work, review inspection reports andrndimensional data, and confirm that the connection to be machined best suits the OD and ID of the tubular.
