Surface Torque maxing out

Folks,

Any pointers will be greatly appreciated.

Issue:  Surface rotary torque maxes @ 30,000 ft-lbs  once landed & 2000´ in lateral

Hole size:  8 /2”  DP:  5” #19.5 S-135

Profile:  surf nudge to 6 deg  & bck to vertical”¦KOP ~ 10,000, 10/100 DLS, land  94 deg ~ 11,000, 2-D well, dropping to 92 deg by TD ~ 18000'

Curve & lateral bha:  5 bladed  PDC, Motor (2deg  fxd bend), MWD, DP---OBM

Torque in vertical:  ~16K ft-lbs”¦once we land out torque goes up to ~24K & to ~30K  around 2000´ into lateral.  Off -btm torque~22K

Can we eliminate hole cleaning as torque goes back up when on btm?...could it buckling?...is it the agressive plan??..any ideas or pointers to check where this excess torque could be coming from?
