Project Description

Project Overview:
We are seeking a senior Reservoir Engineer, Geologist or Petrophysicist to provide a second opinion on a 640-acre parcel in the Byron Field (Bighorn Basin, WY). An initial audit suggested a static Lowest Known Oil (LKO) at -1,550' SSTVD. However, our internal forensic logs and historical production tests suggest a significant Hydrodynamic Tilt that extends the commercial oil bank significantly deeper on our Northwest Ridge.
Scope of Work:
Log Analysis: Conduct a manual petrophysical review of the Phillips State 1 (API 49-003-06429) to reconcile 50–70 Ohm resistivity at -1,754' SSTVD against the regional -1,550' reference line.
Structural Mapping: Integrate the Lodestone 1 (API 49-003-06436) production test (82 BOPD at -2,043' SSTVD) to establish a 3D structural model of the tilted oil-water contact (OWC).
Reservoir Connectivity: Evaluate vertical fracture connectivity between the Phosphoria (Embar) and Tensleep formations based on offset core data (Taw 1).
Production Forecasting: Provide "Low/Base/High" IP scenarios for a 4-well Phase 1 program utilizing modern 28% HCl "Shatter-Zone" acid stimulation.
Required Expertise:
Expertise in Bighorn Basin (Tensleep/Phosphoria) reservoirs.
Experience with Hydrodynamic Trap modeling and Tilted OWC calculations.
Familiarity with historical Wyoming (WOGCC) log sets.
Deliverables:
Revised Volumetric Assessment (OOIP/EUR).
Corrected Structural Map showing the Tilted OWC across Section 16/17.
Technical Memo addressing the validity of the -1,550' LKO versus the -2,043' physical oil shows.
