Abstract
A case study is presented to show how close integration of continual subsurface geological insight and wellsite biosteering data generation<br>and interpretation played a key role in ensuring commercial and technical success of the underbalanced, coiled tubing drilling<br>(UBCTD)campaign at the mature Sajaa gas/condensate fi eld. Reservoir pressure depletion had led to UBCTD being required to increase<br>both rates and reserves. Commercial and technical success was known to depend heavily on maximisation of reservoir exposure in the<br>multiple target intervals within Thamama Group limestones.
