Please i need the answer immediately beacuse i want to compare with my answer is it same or not . please give me two answer for both question because it relate together

Well Lumut-3 has been logged with Pulsed Neutron Capture (PNC) to monitor water breakthrough into Reservoir X. The average Sigma value is 17.8 cu. Reservoir X has porosity of 30%. The following PNC data is obtained from a few nearby wells of Lumut-3 in the 100% water and oil saturation respectively. Table 3 PNC data from nearby wells of Lumut-3 Porosity, (100% S.)

Suggest whether Pulsed Neutron Capture (PNC) log is suitable to monitor water breakthrough for Reservoir Y. Justify your answer. (12 marks) b) If Reservoir Y is a shaly reservoir with shale content (by volume) of 40% and the effective porosity is given as 18%, correct for shale effect and determine the corresponding Sy for Reservoir Y. Assume Sigma shale, sh of 40 c.u
