Jan 2011 – Jun 2012 Schlumberger-DCS, Reservoir Engineer, Algiers, Algeria Jan 2011-March 2011: Phase I for Didon Field, PA Resources, Tunis, Tunisia. The Didon Field is located offshore in the Gulf of Gabes in located next to the offshore border between Tunisia and Libya. The Productive zone corresponds to El Gueria Eocene nummulitic permeability

(up to 1 Darcy). Initial reservoir pressure is 275 bars, only dropped by 13 bars since the start of production which indicating the support of an active aquifer. All Didon wells produce by natural flow. The oil production started on May 1998 from a single subsea well. A total of 10 wells have been drilled in the field.Currently five wells are producing. The STOIIP is estimated at 72 MMbbls

The work done during assignment:

1. Simulation Model review:

CMG-IMEX simulation model is converted to the ECLIPSE Simulation Model

Current Simulation Model Overview

Initial History Match

PVT Review (Differential Liberation Data is adjusted to the separator (flash) conditions. and surface density data is used. After this adjustment in PVT section, there is 7.5% increase in STOIP)

2. Analytical Studies:

Material Balance Study

Fractional Flow Study

WOR Analysis (WOR (Water/Oil Ratio) Analysis is studied Log-Log plot of WOR and Its simple time derivative versus time shows different characteristic trends for different mechanisms. WOR (WOR derivative) shows positive slope for channeling and negative slope for coning)

3. Uncertainty Analysis (Primary basic uncertainty analysis which is done on Field basis with Eclipse.)

April 2011-April 2011: Tifernine field, REPSOL E&P, Algiers, Algeria. Tifernine field was discovered by Sonatrach in the 1960s. The target reservoirs (C1, C2, C3 and C4) are located at an average depth of 1,500m. Repsol began producing Tifernine field since 1998 with an average production of about 1,500 bls/d mainly from C1 reservoir, but the production has since declined due to high water cut from a very active aquifer (current water cut is about 95%). Repsol is looking at the best option to develop both C3 and C4 reservoirs as the most recent well completed in C3 reservoir produced only 25bls/d after stimulation (hydraulic fracturing).

The work done during assignment:

Dynamic Model Preparation

Well Trajectories selection

Horizontal Wells with/without StageFrac

Multilateral Well

Production forecast for the C3&C4 reservoirs of Tifernine field based on single well model

April 2011-May 2011: Phase II for Didon Field, PA Resources, Tunis, Tunisia. The work done during assignment:

History Match (The good match is obtained in terms of Field Reservoir pressure, wells oil production rate, wells cumulative oil production, wells watercut, wells cumulative water production, wells Bottom Hole Pressure (BHP) and wells Tubing Head Pressure (THP).

Three sidetrack locations prepared and current producing wells (D7H and D10H) with these three sidetrack locations were considered as the prediction scenarios.

The prediction showed that for the base case, the remaining reserve is around 2.0 MMstb. An additional one sidetrack well will increase the producible reserves between 0.7 to 1.2 MMstb.

June 2011-August 2011: Bir Sif Fatima (BSF) Field, Groupement Sonatrach-AGIP, Hassi Messaoud, Algeria. (The project is studied in Pau-France). Supporting Reservoir Simulation Study in Pau- France.

The Bir Sif Fatima (BSF) field is located in Block 402a in Algeria and was discovered by well BSF-1 in 1997. Total number of eight wells has penetrated into TAGI reservoir of BSF field up to day. Four of them are producing and remaining are water injection wells. Dynamic Reservoir Simulation Model is generated in order to perform a history match of BSF Field production and pressure data. After the History Match phase the reservoir simulation model was used to understand the range in recovery based on the ongoing development, and to evaluate additional development activities.

The work done during assignment: Supporting the Project`s Reservoir Engineer on:

History Match (Wells Reservoir pressure, wells oil production rate,, wells watercut, wells GOR, wells Bottom Hole Pressure (BHP) and wells Tubing Head Pressure

(THP) for producers and Wells Reservoir Pressure and Wells water injection Rate for injectors. Also available PLT `s and RFT data are also matched)
