Abstract

The idea is to use LWD/MWD data to quantify the potential from a reservoir inflow for discretized sections of long horizontal wells. When the analysis is done through fundamental petroleum engineering driven algorithms, the drilling exercise is flagged for completions to identify that there will be a flow control issue. The inflow/outflow profile is then characterized along the wellbore and an ICD algorithm (pre-built) is run to identify number of ICDs, ICD design, and spacing required to normalize/equalizer the flow along the lateral. This technique couples drilling and completion to help optimize production from long horizontal laterals that are pre-disposed to having unregulated flow control issues due to certain reservoir characteristics including permeability heterogeneities, frictional effects, or reservoir pressure differences.

The invention is live modeling of ICD configurations along the long horizontal wells during the drilling process. Typically, data is collected and sent to reservoir/completion engineers to determine the proper configuration of ICDs and it is typically an arduous process. The idea is to build an algorithm capable of storing the LWD data live and do automated interpretation of the data to output a recommendation on the ICD spacing needed in the well, type of ICD, and number of ICDs that would yield equalization of flow.

the analysis is done through fundamental petroleum engineering driven algorithms, the drilling exercise is flagged for completions to

identify that there will be a flow control issue. The inflow/outflow profile is then characterized along the wellbore and an ICD algorithm

(pre-built) is run to identify number of ICDs, ICD design, and spacing required to normalize/equalizer the flow along the lateral. This

technique couples drilling and completion to help optimize production from long horizontal laterals that are pre-disposed to having

unregulated flow control issues due to certain reservoir characteristics including permeability heterogeneities, frictional effects, or reservoir
