Daily Update - Mohammad Elkady - (June-17-2022)

1.  What did I do today?

Today, I read URTeC: 2455780 and did a little bit of brainstorming and set up a rough timeline for the whole project.

2.  What did I find interesting/Work on? 

URTeC: 2455780

·      This paper presents the case study of two multi-stage, hydraulically fractured, horizontal wells completed in Wolfcamp intervals with over two years of production history. Performances were analyzed using an integrated static Discrete Fracture Network (DFN) and dynamic reservoir simulation model.

·      Inputs into the DFN model include base non-DFN static model and 3D seismic data covering the area of interest, various petrophysical logs from multiple wells in the area, image logs, sonic logs, core data, microseismic, PVT data, historical production and pressure data, DFIT, hydraulic fracture stimulation data and a geomechanical model.

·      The DFN static model, with the estimated properties, is imported into the dynamic simulator as a RESCUE file.

·      Other properties required for model initialization are added (No mention regarding the properties themselves)

Timeline

Important Deadlines

-       January-24: last day to submit proposal

-       March-11: last day to defend thesis

-       March-25: Last day to submit final form of the thesis

Step 1: parameters extraction and Realistic Shale Oil Model building (July – August)

Steps to build a Realistic Model

  1. Compositional (GEM) or Black oil (IMEX)
    1. That depends on how oil density and oil composition availability
  2. Naturally fractured?
  3. Grid numbers and size
    1. That can be assumed
  4. Reservoir Properties
    1. Depth
    2. Temperature
    3. Pressure
    4. Bubble point pressure
    5. Avg Porosity
    6. Avg permeability (I, J, K) for matrix and natural fractures
    7. Natural fracture spacing
  5. Fluid composition and saturations and relative permeability curves
  6. Water-Oil contact depth
  7. Adsorption data
  8. Well Completion and Hydraulic fracturing data
    1. Perforations
    2. Fracture width, half length, frac permeability

Q: This for only specific formation should we consider other areas in the Permian?

 Step 2: Simulate Different Scenarios for every model (Sept – Oct – Nov)

-       To be determined.

Step 3: Statistical study on water production (Dec – Jan)

-       Main reasons for excessive water production

-       Solutions for reducing water productions

-       Best way to make use of produced water.

Step 4: Thesis writing (Feb – Mar)

 

3.  What will I do next? 

I will look for public production data and gather the required parameters and inputs to build the required model.
