During the development phase, wells are drilled with the primary objective of hydrocarbon production. This is the phase in the field or reservoir life-cycle where the development plan is implemented. There is a strong economic incentive (time value of money) for developing the field or reservoir.
During the development phase of the life-cycle, the rig schedule is almost exclusively dedicated to drilling the wells considered in the original development plan. During development drilling, the learning curve becomes steeper (more is learned over a shorter period) and the drilling times typically become shorter as the drilling engineers and drilling crews make use of the lessons learned from previous wells.
