Extended Lateral Solutions for an Extremely Difficult Well Trajectory by Larry Albert, Allied Horizontal Wireline Services


An E&P operator suffered numerous drilling problems when trying to build angle and land horizontal laterals in a field in Oklahoma and was forced to modify the drilling plan to drill below the reservoir and then angle back up to the target. After reaching the base at a measured depth of 14,000 ft. the well plan was drilled up at maximum of 114° until reentering the target reservoir. Because of faulting in the area and required well direction, the target reservoir was dipping up at ~10° laterally in the direction of the horizontal drilling target. To maintain position in the reservoir, the well had to drilled at ~100° deviation to a measured depth of 21,100 ft.

This wellbore trajectory made normal wireline plug and perforating completion operations extremely difficult. The high wellbore angle meant high frictions on the wireline when coming off bottom. Also, due to the toe-up trajectory there was risk the wireline tools would slide down the inclined casing during and after plug setting and perforating. If the tool position could not be maintained there was risk the wireline cable could be entangled and a stuck tool could result. If the tools overrun the wireline cable the result could be wireline cable next to the perforating guns when detonated and wireline cable severed.

To meet the challenge several new methods and technologies developed for extended laterals were utilized. These products and methods included: advanced risk deployment modeling, jacketed wireline cable, addressable separation tool and downhole tension tool.
