Candidate # NA-3785682434

Sr. Reservoir Engineer

 

                                                                                Summary

Since 1980, worked on a variety of oil, gas and gas-condensate reservoirs, in clastic and carbonate formations. Tasks included drawing development plans for new reservoirs, management of mature assets, and evaluations of prospects. I have used simulation extensively, and come to recognize that models may be of little value, unless they are based on reliable logging, PVT, special core analysis, and transient well test data, plus thorough reservoir characterization. My aim has always been to optimize recovery, reduce costs, and in general, propose pragmatic development, and workover plans. Similarly, regarding evaluations, I have always sought to present objective assessments, based on the available data, and the performance of analog reservoirs.

                                                                              Experience

 

2007- 10/2010. At  the Houston  office  of  BHP-Billiton,  completed  history  matching  the  performance  of  three reservoirs of  the Angostura Field, in Trinidad  and Tobago. Heavy  faulting and  the  need  to  incorporate a pipeline system  to  the combined  model  made  the  project extremely challenging. Angostura has  a STOIIP of  300 mmstb  and  a GIIP of 900 bscf.

Marathon Oil 1984-2007

1998-2007. At the Lafayette, and Houston offices of Marathon Oil Company, worked on the following projects:

-NC-98 Reservoir in Libya. Geology: Clastics. Reservoir fluid: Wet gas and volatile oil. GIIP: 3.0tscf.  STOOIP: 1.0 billion barrels. Responsibilities: Liaising with laboratories to set up PVT and SCAL experiments, evaluation of existing PVT, special core analysis, and well test data, plus drawing alternative development plans involving different plateau rates, for reservoir pressure blow down, and gas recycling scenarios.

-Faregh Reservoir in Libya. Geology: Clastics. Reservoir fluids: Oil and wet gas. GIIP: 7.0tscf STOIIP: 1.5 mmstbo. Responsibilities: Well test analyses, and evaluation of different development scenarios using the ECLIPSE 200, and ECLIPSE  300 software.

-Defa, and Darra-Joffra reservoirs in Libya. Geology: Clastics. Reservoir fluids: Oil and  gas. Defa STOIIP: 9.0 mmstbo. Darra-Joffra STOOIP: 4.5 mmstbo, GIIP: 1.8 tscf. I was a member of a joint Marathon-ConocoPhillips-Hess team, whose tasks were planning the re-development of the said reservoirs. 

-Petronius  in the Gulf of Mexico. Geology: Unconsolidated sandstone. Reservoir fluids: Oil and gascap gas. STOIIP: 550 mmstbo. Responsibilities: Revision of  the development plan. Evaluation of the field data, and history matching led to modifications that increased the oil rate by 12000 stbo/d.         

-Camden Hills in the Gulf of Mexico. Geology: Unconsolidated sandstone. Reservoir fluid: Dry gas. GIIP: 170 bscf. Responsibilities: Drawing of a development plan, and designing the pipeline to gas gathering center. 

-Ewing Bank in the Gulf of Mexico. Geology: Unconsolidated clastics. Reservoir fluid: Undersaturated oil. STOIIP: 350mmstb. Responsibilities: History matching the performance of the reservoir during the years 1994 – 1999. Modeling led to radical revision of the drilling and recompletion programs

-South Pass C and D Reservoirs in the Gulf of Mexico. Geology: Sandstone. Reservoir fluids: Saturated oil and gas. Hydrocarbon initially in place: 85mmstbo and 285bscf. Two models were built and history matched. Results were used to obtain permission from the MMS to blow down the said reservoirs.

1987-1998. At the Production Technology Center of Marathon Oil Company, in Littleton Colorado, I worked on the following projects:

-Lagunillas, Intercampo, Dacion  and Mata-Acema Reservoirs in Lake Maracaibo, Venezuela. Geology: Sandstone. Reservoir fluid: Oil of gravity in the range 15-32 degrees API. Combined oil initially in place: 7.0bstb. As a member of a multidisciplinary group, my responsibility was to assess the future potential of these reservoirs. This was accomplished through decline curve analyses, and  simulation of the heavy oil reservoirs.

-Oyster Reservoir in the Gulf of Mexico. Geology: Unconsolidated sandstone. Reservoir fluid: Undersaturated oil. STOIIP: 40mmstb. Responsibilities: Drawing of a development plan of this reservoir.

-North Brae Reservoir in the British Sector of the North Sea. Geology: Sandstone and conglomerate. Reservoir  fluid: Gas condensate. GIIP: 1.2tscf.  Development plan based on gas recycling, partial blowdown and final blowdown. Responsibilities: History matching the performance of the reservoir from 1988 through 1996, using ECLIPSE 300. Through prediction runs, I was able to demonstrate that condensate recovery could be improved by replacing crestal with peripheral gas injection, in the top layers of the reservoir.

-East Brae Reservoir in the British Sector of the North Sea. Geology: Sandstone and conglomerate. Reservoir fluid: Gas condensate. GIIP: 2.1tscf. The development plan of this reservoir was similar to that of North Brae.  Responsibilities: Reverse decline in condensate production After history matching the reservoir model, a  re-completion plan was devised, that increased the condensate rate by 13000 bcpd.

-South Brae Reservoir in the British Sector of the North Sea. Geology: Sandstone and conglomerate. Reservoir fluid: Undersaturated oil. STOIIP: 760mmstb. Responsibilities: Construction and history matching a model with an extended grid that included the nearby Miller, East Miller and Central Brae reservoirs which were in communication with South Brae. 

 Additional modeling work involved evaluation of a pilot water-alternating-gas scheme (WAG). To this end the model was modified to include the Todd and Longstaff approximation, and additional information from whole core WAG floods. Swollen oil PVT input had been incorporated during history matching. Main conclusion was that WAG could be significantly more effective than straight forward water injection.  

-East Cameron Reservoir in the Gulf of Mexico. Geology: Clastics. Reservoir fluid: Undersaturated oil. STOIIP: 20mmstb. Using a history matched model, I was able to show that water injection could be discontinued without reducing recovery.

-Yates Reservoir in Texas. Geology: Carbonates. Reservoir fluid: Saturated oil. STOIIP: 4.0bstb. Reservoir  plan: Production from oil leg fractures, supported  by  crestal  carbon dioxide, and  nitrogen injection, plus aquifer influx. Responsibilities: History  matching the field performance of the period 1927 – 1995 using the  dual porosity-dual permeability option of ECLIPSE 200. Matching  parameters  were the pressure data,  the depths of the gas-oil, and oil-water contacts as functions of time, and log derived gas-cap oil saturation data. Modeling confirmed  that production was maintained through drainage of oil trapped, in the gascap matrix blocks. Prediction runs showed that increased gas injection accelerated drainage, and capacity was increased accordingly.

-Indian Basin Reservoir in New Mexico. Geology: Carbonates. Reservoir fluid: Wet gas. GIIP: 2.0 tscf. Responsibilities: Build and history match a model with data of the period 1962-1989, to assess the potential of horizontal wells, and gas compression requirements.

-Sand Dunes Reservoir in Wyoming. Geology: Clastics. Reservoir fluid: Undersaturated oil. STOIIP: 2.0mmstb. Responsibilities: Design a development scenario based on gas injection at minimum miscibility pressure.

-Kakap-KH7 Reservoir in Indonesia. Geology: Clastics. Reservoir fluid: Undersaturated oil. STOIIP: 97mmstb. Responsibilities: STOIIP determination, from material balance calculations, and modeling.

-Alba Reservoir in the British Sector of the North Sea. . Geology: Clastics. Reservoir fluid: Undersaturated oil. STOIIP: 1.2bstb. Responsibilities: Drawing a development plan.

-McArthur River Project. –G Zone and West Foreland Reservoirs in Alaska. Geology: Clastics. Reservoir fluid: Undersaturated oil. STOIIP: 300mmstb. Responsibilities: Comprehensive workover plan through modeling.

In addition to the aforesaid, I also worked on projects of shorter duration such as: transient analyses; modeling of hydraulically fractured, conventional, and horizontal wells; proposals for workovers and/or new well locations for various projects; and  recommendations for well tests and logging surveys. 

 

1984-1987. At the Aberdeen , and London offices of Marathon Oil UK Limited, I worked on the following projects:

 

-North Brae Reservoir in the British Sector of the North Sea. Geology: Sandstone and conglomerate. Reservoir fluid: Gas condensate. GIIP: 1.2tscf. Responsibilities: Creating a development plan based on gas recycling, partial  blowdown and final blowdown of the reservoir, using ECLIPSE 300.

-South Brae Reservoir in the British Sector of the North Sea. Geology: Sandstone and conglomerate. Reservoir fluid:  Undersaturated oil. STOIIP: 760mmstb. Responsibilities: Build a history matched reservoir model, as dictated by the UK Department of Energy.

-Logging and testing of Marathon wells in the North Sea. These included PLT, RFT, pressure build-up and fall-off surveys, plus collection of PVT samples. Duties involved writing procedures, supervision of field work and analyses of the acquired data.

1979-1984. At the Glasgow office of  Britoil Plc, I worked on the following projects:

-Ninian Field in the British Sector of the North Sea. Geology: Clastics. Reservoir fluid: Undersaturated oil. STOIIP: 2.6bstb. Responsibilities: Built and history match a model with data of the period 1978-1983; use model to evaluate proposals, for further development, put forward by the operator, Chevron Petroleum UK Ltd; represent Britoil at reservoir engineering meetings with partners and approve AFE’s.
