Conducted reservoir simulation studies for development of the Arab-D reservoir to understand field potential and maximize the production of Arab extra-light crude. Also conducted dual-porosity and dual–permeability simulation of the Hanifa reservoir for horizontal drilling project.
Modeled the Arab-D reservoir in the ‘Ain Dar and Shedgum areas under various operating scenarios. Studied the effects of production-rate increases on facility and well requirements and on ultimate recovery. Also determined the effect of gas-cap blowdown timing on ultimate oil recovery. Revised reservoir description, assessed water movement, determined permeability distribution, delineated the tar mat and determined effect of aquifer on tilt of oil-water contact. Also performed reservoir simulation studies of the South Uthmaniyah and Hawiyah areas to evaluate reservoir potential and to assess the timing and capacities for water-handling facilities. Also, performed horizontal-well simulation studies as well as buildup test analyses, core analyses and other miscellaneous technical studies. Also, evaluated and delineated reservoir, conducted and supervised well tests, performed reservoir simulation and recommended development program for undeveloped zone in the Arab D reservoir.
Safaniya and Berri field
Conducted compositional modeling, using three-parameter Peng-Robinson equation of state, to characterize reservoir fluid samples. Performed numerical separator tests to obtain estimates of fluid properties within the separator. Simulation results were used in design of well test separator facilities.
Quantified country’s solution gas reserves and performed a study of oil reserves. Estimated daily gas deliverability over a 20-year forecast period to help assess the potential for extracting and marketing sulfur. Project involved the feasibility of financing and constructing sulfur-extraction facilities.
Audited available seismic data to verify the shape and extent of this broad, four-way structural trap. Petrophysical analysis of the three field wells yielded the pay thickness and rock properties necessary to help build the model of proved volumetric reserves within the Triassic Argilo-Greseux Inferieur (TAGI) formation.
El Franig field
The field is an elongated structural high trapped on one side by a sealing fault. Three wells produce the gas-condensate reserves of the fractured Hamra and El Atchane formations. Evaluated the initial volumetric reserves discovered by the three wells. In addition, evaluated the producing nature of this gas-condensate field to help optimize hydrocarbon recovery.
Evaluated the available seismic to delineate the structural composition of this one-well field. Structural review showed that the field is probably two, separate, four-way, structural closures with either a low structural area or possible sealing fault between the two closures. Evaluated the volumetric reserves for the TAGI formation on the south structural high. Projected the reserves within the undeveloped portion through seismic analysis.
