The paper mentions the amplitude variations with offset AVO technology was introduced over 20 years ago. In the intervening years, the technique has evolved from a concept to a primary component of seismic exploration. AVO methods can add reliable constraints to quantitative reservoir characterization if the operator understands the underlying...
The paper states that the Kansas Geological Survey has developed new technologies and strategies to improve oil recovery from Kansas's oil fields. The focus has been to provide increased access to public data through online digital programs, development of software to evaluate electric logs, improved reservoir characterization, modeling and computer...
The paper mentions that as production from conventional reservoirs in the continental U.S. is decreasing, gas from the Lewis and similar unconventional reservoirs will become increasingly important for future gas supply. Significant Lewis Shale gas reserves may be commercially accessible in old and new wells within the San Juan Basin....
The paper mentions that The University of Illinois has concentrated on improved methods of digital mapping, including Trend Analysis and 3-D Modeling. Trend Analysis is based on a method for differentiating regional and local components in a map area. Three-dimensional modeling provides a tool for visualization of the spatial distribution...
The paper cites that corrosion can be uniform, or of a pitting nature where penetration rates can be very high. Corrosion severity is influenced by temperature, pressure, pH, velocity, and wear/abrasion, among other factors. Corrosion inhibitors, which are typically organic amine-based compounds, function by establishing a film that protects metal...
The paper reveals that wireline logging tools have come a long way since the original spontaneous potential and resistivity tools became available decades ago. Today wireline logging tools provide basic reservoir data to operators and play a fundamental role in determining stratigraphic correlations, lithology, wellbore conditions, fluid type and saturation,...
The paper mentions that a periodic review of reservoir production practices and performance data, coupled with maintaining an awareness of newly developing technologies and techniques, is a good recipe for reservoir management success. Through production optimization methods, costs can be reduced and output increased. It adds that with the prevailing...
The paper mentions that water production, with its associated costs, can be minimized by using the proper drilling techniques, using the proper logging and perforation techniques, chemically or mechanically closing down high-permeability streaks, or separating the water from the oil downhole. Logging is important not only for identifying water zones...
The paper mentions that coiled tubing has several distinct advantages for well fishing operations. It offers additional tensile strength above that of braided line and the ability to use heavier tools is helpful in most applications. The capacity to circulate fluid through the system can also be helpful in some...
The paper mentions that by-passed hydrocarbons are best located using a variety of reservoir characterization techniques and technologies. Well-defined petrophysical properties are fundamental to understanding fluid saturation and distribution in reservoirs. New techniques such as Moving Domain and recent advances in accurate 3-D geologic modeling and nonparametric statistics can significantly...
The paper mentions that unanticipated reservoir heterogeneity may significantly hinder fluid production. A variety of techniques are available to help operators accurately describe reservoir compartments and their distributions. Integrated analysis considering results from varied techniques increases understanding of reservoir compartments, and ultimately raises production. It also adds that Reservoir heterogeneity...
The paper states that new wireline logging technologies make it possible to collect reservoir property information critical to reservoir decision-making that used to be obtainable only from riskier, more expensive oriented and native-state coring. It also adds that detailed and accurate reservoir and wellbore descriptions in mature reservoirs are needed...
The paper reveals that there are several innovative new techniques available to help operators enhance the monitoring of downhole conditions, model reservoir complexity, lower water disposal costs, and optimize the ultimate recovery of oil and natural gas. Operators increasingly use a broad spectrum of innovative technologies to improve geophysical interpretations,...
The paper mentions that seals are commonly an overlooked component in the evaluation of a potential hydrocarbon accumulation. Seals can be detected by a variety of tools such as pressure tests, seismic amplitude analysis, and high pressure capillary curves. Capillary pressure tests are a very useful method to evaluate seals.
The paper mentions that technology advances in underbalanced drilling, mud logging equipment, real-time monitoring of hydraulic fracturing treatments, well stimulation with water fracs, and borehole imaging and cased-hole logging tools each, when applied properly, can improve well/lease profitability. But this improved profitability comes only when the advantages/ limitations and proper...
The paper points out that by sharing successful reservoir management approaches, including reservoir descriptive techniques and methods for applying recovery technologies, operators of turbidite reservoirs in California can increase their production and reduce costs. All operators benefit by the decreased "learning curve" for recovering oil resources remaining in these reservoirs.
The paper mentions that integrated, multi-disciplinary reservoir characterization and simulation studies of tight gas sandstone reservoirs in the San Juan Basin are required to determine the optimum location and expected recovery from infill wells. Core and outcrop analysis, seismic data, production data analysis techniques and reservoir simulation are tools used...
The paper cites that advanced technologies including computer visualization, multi-component seismic, fracture modeling, and borehole imaging are being developed by the Bureau of Economic Geology, The University of Texas at Austin. Opportunities exist for operators to participate with the Bureau in characterization and reservoir exploitation studies to increase oil and...
The paper mentions that operators can use surface geochemical techniques for reservoir characterization, field development, and monitoring production patterns, as well as more established uses for high-grading leases, and prospects. Wider usage of surface geochemical exploration methods in mature basins also shows great promise. It also states that hydrocarbon micro-seepage,...
The paper cites that wireline logs historically have been and continue to be the most critical and widely available tools for characterizing and managing reservoirs. Reservoir producibility and economics are being improved with new technologies for gathering and interpreting formation properties in open holes and behind pipe, coupled with new...
