Time-lapse multi-component seismic monitoring, Delhi Field, Louisiana
First Break, 2015Co-Authors: Thomas L. DavisAbstract:Thomas L. Davis characterizes the Delhi Field in Louisiana by monitoring flow paths associated with immiscible Carbon Dioxide Flooding. Time-lapse, multi-component seismic data were acquired during the start-up of the field rejuvenation effort at Delhi Field, Louisiana. The purpose of the study was to characterize the reservoir by monitoring flow paths associated with immiscible Carbon Dioxide Flooding. Flow paths in the reservoir are associated with primary depositional facies involving fluvial deltaic deposition. These flow paths cannot be assessed by wells alone making seismic monitoring a valuable tool in the enhanced oil recovery project at Delhi.

The state of EOR with CO2 and associated seismic monitoring
Geophysics, 2010Co-Authors: Thomas L. DavisAbstract:Carbon Dioxide (CO2) can be an agent for enhancing recovery from oil reservoirs because it acts like a scrubbing agent to contact residual oil in the reservoir and makes it easier for the oil to flow to producing wells. Old reservoirs that have produced for years are not depleted of oil. They contain residual oil that can't be moved under primary or secondary flood processes. The tertiary process that could move the greatest amount of residual oil is Carbon Dioxide Flooding. To obtain the residual oil, we need to inject CO2 to enhance oil recovery (EOR). We may be able to produce up to 20% of the original oil in place (OOIP). Seismic monitoring provides a means to proactively manage the flood.

advanced reservoir characterization to evaluate Carbon Dioxide Flooding spraberry trend midland basin texas
AAPG Bulletin, 2000Co-Authors: Scott L. Montgomery, David S Schechter, John C LorenzAbstract:The Spraberry trend area of west Texas, once known as the "largest uneconomical field in the world," contains as much as 10 billion bbl of original oil in place. These hydroCarbons are stratigraphically trapped in fine-grained, low-permeability, and naturally fractured siltstones and sandstones deposited in submarine fans of Permian age. Despite five decades of production, including several large-scale waterflood projects, recovery from the Spraberry rarely exceeds 8-12%. Lack of scientific attention since the 1960s has resulted in most core samples suffering deterioration and loss, hampering any application of new methods for reservoir analysis.

Delaware Mountain Group, West Texas and Southeastern New Mexico, A Case of Refound Opportunity: Part 1—Brushy Canyon
AAPG Bulletin, 1999Co-Authors: Scott L. Montgomery, John Worrall, Dean HamiltonAbstract:Exploration in Permian (Guadalupian) deep-water sandstones of the Delaware Mountain Group, west Texas and southeast New Mexico, represents a success story of the 1990s derived from reevaluation of reservoirs previously deemed uneconomical. Recent discoveries have concentrated on the Brushy Canyon in New Mexico and, to a lesser extent, the Cherry Canyon in Texas. Brushy Canyon reservoirs in particular previously were overlooked due to indications of poor reservoir quality from log and well test data; however, oil shows observed on mud logs across the northern Delaware basin led to new completion efforts in the late 1980s and 1990s using gel-sand fracture stimulations. Productive reservoirs are very fine to fine-grained arkosic to subarkosic sandstones with porosities of 12-25% and permeabilities typically of 1-5 md. Better reservoir quality is concentrated in massive channel sandstones variably interpreted as deposited by turbidity or saline density currents. Significant clay content, lamination, and close interbedding between oil- and water-bearing units make log analysis and reserve estimates problematic. As a result, the mud log remains the cheapest, most practical indicator of pay. Reservoir sandstones can be divided into a series of major productive trends related to proximal/slope and more distal/basin-floor depositional settings. Well productivity is variable within each trend, but primary recovery rarely exceeds 10%. Options for enhanced recovery include pressure maintenance, waterFlooding, and Carbon Dioxide Flooding. Early indications suggest that Carbon Dioxide Flooding may be most appropriate in these low-permeability, clay-bearing reservoirs.

Compositional Changes and Rheological Properties of Athabasca Bitumen under CO2/O2 Mixtures Associated with Carbon Dioxide Flooding/Sequestration Process
Industrial & Engineering Chemistry Research, 2007Co-Authors: Na Jia, Gordon R. Moore, Sudarshan A. Mehta, Elizabeth Zalewski, Matthew G. UrsenbachAbstract:Research described in this paper was conducted in support of a more extensive study that has been ongoing at the University of Calgary to quantify the effect of the presence of Carbon Dioxide and oxygen mixtures in an Athabasca bitumen reservoir undergoing a Carbon Dioxide Flooding/sequestration process. This paper concentrated on the compositional and rheological changes of Athabasca bitumen. The experiments were performed in the oscillating batch reactor using clean oil plus distilled water only. Viscosity was measured, and the compositional data were expressed in terms of the components maltenes, asphaltenes, and coke. In CO 2 /O 2 tests, the amounts of maltenes decreased with increasing reaction temperatures as a result of conversion to asphaltenes and coke. The data had direct applicability to recovery processes involving the injection of Carbon Dioxide containing oxygen as an impurity in the bitumen reservoir.
