Minimizing Environmental impact & Nuisance(ess e3ipment makes operation more & more important
to redce environmental impact.
The rig weight and drilling string weight for slimhole
drilling are mch less than conventional drilling.
8ir polltion is also redced becase less power isre3ired
9oise !edction
!edction in transportation for mobili#ation &demobili#ation of drilling e3ipment.
7el consmption and gas emissions to the atmospherecan be proportionately redced.
