Abstract
In a broad aspect, the invention may include a nipple, a deflector, and a conveying tool. The nipple may include an upper sealing surface and a lower sealing surface. The nipple may also include a discriminator/muleshoe having an alignment profile and an alignment slot. A protuberance/bump may be disposed in the alignment slot. The deflector may include an upper seal and a lower seal adapted for engagement with the upper and lower sealing surfaces, respectively, on the nipple. When the upper and lower seals are engaged with the upper and lower sealing surfaces, fluid circulation is substantially restricted thereby resulting in a increase in pressure that is detectable at the earth's surface. This pressure increase provides a signal that the deflector is properly positioned in the nipple. The conveying tool may include a flexible arm having a latching finger that is releasably engageable with a latching profile in the deflector. The latching profile may be on an inclined, concave surface of a whipstock. Related methods are also provided.
