Zupt’s W-PINS is an inertial survey tool that provides accurate and precise surveys in various types of well bores, including steam-assisted gravity drainage (SAGD) wells. W-PINS is a fully integrated system with three navigation grade rate gyros and three high specification accelerometers.
Increased accuracy of well positions lead to cost savings and increased production. While other methods claim 0.3% to 3% radial accuracy, they offer no way to refute or support those claims. Zupt’s method provides a misclosure at the end of a traverse, from wellhead to Total Depth (TD) and back, to reflect a true accuracy. W-PINS can provide a detailed x, y, z position profile of the well, along with high resolution attitude data with results less than 0.1% of the distance travelled on multiple runs.
Upon configuration and deployment at the surface, the W-PINS system operates fully autonomously for up to six hours to collect the required measurements as the tool is lowered through the well. The system can be housed for deployment on either coiled tubing or on a wireline well tractor, and has been designed to fit into a cased hole of as little as 6 inches in diameter.
