Reservoir, well and surface equipment conditions change as oil and gas are extracted. To manage reservoirs effectively, Occidental’s multi-disciplinary teams collect and analyze data and take the appropriate steps to optimize production and reserves.
The data, much of it from automated systems, includes pressure, temperature, production and injection rates, artificial lift efficiency and surveys of downhole conditions (also known as well logs). Changes in these variables are interrelated; continuous monitoring enables Occidental professionals to make prompt adjustments that improve oil and natural gas production.
Occidental also uses performance prediction tools such as reservoir simulation and compares the results with actual performance. Based on the findings, opportunities are identified to fine-tune field development, EOR programs, artificial lift design and well servicing plans.
