"Pryor Oil has maintained a crew of 4 employees who have worked diligently over the last two months on the pipeline as weather permitted. The payroll and expenses to date have added up to approximately 90,000".

This document is an affidavit, so it is likely to be accurate because in discovery proceedings opposition lawyers can question the person who gives the affidavit.

The affidavit gives the impression that the pipeline is nearly complete. I would guess about 2/3.

2/3 of job is $90,000

Total job = 135,000, allowing for inflation approximately $300,000 based solely on the incomplete data in the affidavit.
