The use of coiled tubing for re-entry and horizontal drilling

To increase production from layers of low permeability or depleted reservoirs it is necessary to use some new technologies. One of them is the use of coiled tubing (CT) for re-entry and horizontal drilling. When new technology is to be used the necessity of technical and ecconomical feasibility is obvious. Because of technological improvements drilling with CT must be evaluated in such way for each projekt, wheather one well or a number of them will be drilled. When technicaly feassible a project must also be ecconomically feasible. In such analysis the competitiveness between conventional solutions and CT application must be evaluated.
