AUTOMATED, REAL-TIME FORWARD MONITORING OUTPERFORMS TRADITIONAL MATHEMATICAL PROJECTIONS

H&P discussed these challenges with the operator and encouraged them to embrace automated technology to reduce uncertainty and maintain consistent, reliable results. H&P’s automated Bit Guidance System makes intelligent decisions based on economics and delivers real-time information, like slide reports, survey reports, drilling parameters and well plan information.

By utilizing automated rig state detection, toolface orientation, recent dynamic motor yield and motor potential while sliding, and recent BHA tendencies while rotating, the H&P Bit Guidance System determined that the 29 degrees inclination projection that was calculated via legacy methods by the human directional driller was incorrect, and its actual value was a 25 degree inclination.

Additionally, the higher accuracy of the bit position and trajectory by the Bit Guidance System determined a longer slide interval to precisely land the curve (the automated Bit Guidance System determined a 67 ft slide would be required, which is 25 ft longer than determined using a non-automated process). Because this automated technology had only been newly introduced to this operator, there were naturally reservations on trusting machine over man. As a compromise, the driller decided to split the difference between the two methods (manual and automated) and slide 57 feet. After drilling the next stand, a survey was acquired showing an inclination of 32.6 at the sensor and a “build rate to land” was calculated as 7.8 degrees per hundred feet. This required nearly 100% sliding to land the curve. If the driller had performed the shorter slide as determined using legacy projection methods, he would have landed short, which would have led to a sidetrack and additional costs. The automated system estimated the position of the bit with more accuracy because it used more of the available data along with automated forward modeling algorithms to utilize this data in real-time. In the case study, the directional driller did not fully follow the algorithm, however they did increase the footage slid. In this instance, the algorithm actually saved a bit trip.

DRILLSCAN® SOFTWARE IDENTIFIES DRILLING DYSFUNCTION CAUSES IN COMPLEX, MULTILATERAL ERD WELL

Image
An operator in the North Sea faced a lower completion lock-up 800m above total depth (TD), followed by a stuck pipe event in an ERD multi-lateral well. In an initial effort to push the completion down to TD, all slack off weight and torque margin were used. Since no improvement was observed, the decision was made to pull-out. However, the string remained stuck and despite the rig efforts to free it, the lower completion had to be cut and left in hole. H&P’s DrillScan® technology team performed an in-depth post-analysis, reviewing all available data to identify what might have caused the lock-up event. The data provided was used to simulate the downhole conditions undergone by the completion with the DrillScan genuine stiff-string model. The results and conclusions pointed to string dysfunctions: suboptimal tripping and lubricating/ backreaming practices (BHA POOH) led to repeatedly exceeding the screens yield strength (lower completion RIH). H&P’s DrillScan software was a...
