This book was released on 1993 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the remaining oil offshore is trapped in formations that are extremely complex due to intrusions of salt domes. Conventional seismic processing techniques cannot clearly image either these traps or the full extent of oil-bearing segments near the salt domes; therefore, substantial volumes of oil may have remained uncontacted by previous drilling. Recently, however, significant innovations have been made in seismic processing and mathematical migration of seismic signal. In addition, significant advances have been made in deviated and horizontal drilling technologies and applications. These technology advances make it possible to reprocess existing seismic data to identify non-contacted portions of the reservoirs, which can then be contacted using advanced drilling technologies to kick out new wells from existing wells. Effective application of these technologies, along with improved recovery methods, offers opportunities to significantly increase Gulf of Mexico production, delay platform abandonments, and preserve access to a substantial remaining oil target for enhanced recovery and other advanced recovery processes. During this reporting period, data collection continued from the Minerals Management Service (MMS) and several operators. Modifications to BOAST II and MASTER reservoir simulators for the integration of radial grid systems and for use in simulating miscible gas injection processes in steeply dipping reservoirs continued. The testing of the experimental apparatus designed for studying the recovery of attic oil began. Analysis of data obtained from Taylor Energy in South Marsh 73 field continued.

This book was released on 1993 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: During this reporting period, data collection from the Minerals Management Service (MMS) was completed and continued from several operators. Data analysis continued on Reservoir 3 in Field 2. Evaluation included well log analysis, pressure and production data analysis, evaluation of PVT data and development of preliminary model grid schemes. Material balance and computer simulations studies of the B-65-G Sand reservoir, in South Marsh 73 Field, also continued. Work continues on refining the match for use in predictive runs. Four wells produced from the reservoir; three injected some quantity of gas and one well injected no gas. A fifth downdip well, served as a primary gas injector. The reservoir model was developed by integrating geologic and engineering data. The reservoir is a long, north-south trending, steeply dipping sandstone, which pinches out just before encountering a piercement salt dome. The reservoir produced 3,909.8 MSTB of oil, 3,760.2 MMCF (2,745 MMCF was re-injected) of gas and 545 MBbls of water over a period of 27 years. Originally, it was believed that the reservoir was subject to a fairly strong water drive. However, upon performing material balance studies it was found to have a very weak and limited water drive. This was later confirmed by the simulation work. A 2D adaptive finite element model capable of simulating oil/water flow in a porous media was constructed. These results have been submitted for publication and accepted for presentation in March, 1994. In addition, a manuscript describing the construction of a new finite element for use in 3D adaptive methods has been submitted for review.

Download or read book Assist in the Recovery of Bypassed Oil from Reservoirs in the Gulf of Mexico Final Quarterly Status Report October 1 1993 December 31 1993 written by and published by . This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maps collected at the MMS office in New Orleans were planimetered and measured. Measurements of estimated salt diameter and updip areas are also being derived. Production data was read from the tapes obtained in New Orleans and reformatted for use in TORIS. Conceptual work began on the development of the models required to assess unrecovered oil, continued primary recovery of existing mapped oil, updip attic oil recovery, and miscible and immiscible CO2 injection recovery. Efforts began to supplement existing TORIS data with drilling, workover and facility costs related to past enhanced oil recovery, efforts in the offshore Gulf of Mexico area. Data on CO2 sources was collected and byproduct CO2 costs were estimated for use in the economic model. LSU continued the analysis of data obtained from Taylor Energy on the South Marsh Island (SMI) Block 73 Field and the blindcoded Field 2, both in the Gulf of Mexico. The apparatus for experiments for the study of attic oil recovery techniques is being tested. Tests of the 2D adaptive finite element model continue, simulating oil/water flow through porous media. Although coning traces are being produced similar to those in the Lance Hebert thesis, oscillations are still a problem. The Master modification has been completed and currently undergoing testing.

This book was released on 1993 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to assist the recovery of non contacted oil from known reservoirs on the Outer Continental Shelf in the Gulf of, Mexico. Mature off shore reservoirs, declining oil reserves, declining production, and other natural forces are accelerating the abandonment of offshore oil resources and production platforms. As these offshore wells are plugged and the platforms are abandoned, an enormous volume of remaining oil will be permanently abandoned. Significant quantities of this oil could be recovered using advanced technologies now available if the resource can be identified. During this reporting period, ICF Resources Incorporated (ICF), a subcontractor for the project, continued to collect data from Minerals Management Service (MMS) and LSU continued to collect data from several operators. LSU also continued to modify BOAST II for the integration of radial grid systems and the building of the experimental apparatus for studying the recovery of attic oil. BDM Federal, Inc. (name changed from BDM International, Inc.) (BDM), a subcontractor for the project, began modifying the MASTER reservoir simulation model for use in simulating miscible gas injection processes in steeply dipping reservoirs. LSU and BDM Federal. Inc. began analyzing data obtained from Taylor Energy in South Marsh 73 field.

This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to assist the recovery of non contacted oil from known reservoirs on the Outer Continental Shelf in the Gulf of Mexico. History matching and prediction runs have been completed on the B-35-K reservoir, history matching has been completed on the B-65-G reservoir and on Reservoir 3. Modifications to BOAST II and MASTER consisted of developing codes to handle steeply dipping oil reservoirs and a radial grid format for near wellbore studies. Modifications for steeply dipping reservoirs have been successfully implemented and tested against commercial simulators in the PC version of BOAST II, renamed BOAST III. At present, modifications to BOAST II for radial grid systems are producing acceptable results in a 2-D model. A paper was presented at the 1994 ACM Symposium on Applied Computing in Phoenix, Arizona, March 6--8, 1994 on these results. Modifications have also been successfully implemented in the MASTER simulator. It is presently undergoing industry testing for validity. Laboratory investigations continued but were slowed by several unforeseen incidences involving broken apparatus and inability to receive parts due to the California earthquake. Predictive models for undeveloped oil and immiscible/miscible processes began. The methodology for determination of undeveloped potential has been completed. The design of the miscible and updip displacement models as well as the design of the economic and timing models is underway. The coding and calibration of the models will begin soon.

This book was released on 1993 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to assist the recovery of non-contacted oil from known reservoirs on the Outer Continental Shelf in the Gulf of Mexico. Thus far, research has consisted of data collection from Minerals Management Service (MMS); literature and operators; screening of reservoirs for detailed studies; modification of two public domain simulators; development of a predictive model; and design of several laboratory experiments for studying attic oil recovery. The methodology for data collection from MMS, literature and operators is keyed on 208 sands containing 1,289 reservoirs, representing 60% of the original oil in place (OOIP) in the Gulf of Mexico. This data collection is presently in progress after several delays concerning confidentiality agreements between MMS, DOE, and LSU and its subcontractors. Modifications on two public domain computer reservoir simulators, BOAST II and MASTER, is underway. Modifications will consist of developing a code to handle steeply dipping oil reservoirs and a radial grid format for near wellbore studies. Modifications for steeply dipping reservoirs have been successfully implemented. At present, modifications to BOAST II for radial grid systems are producing acceptable results in a reasonable, though long, period of time. Research of all phases listed above are in progress; therefore, no results or conclusions can be reported at this time.

This book was released on 1995 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gulf of Mexico Basin offers the greatest near-term potential for reducing the future decline in domestic oil and gas production. The Basin is less mature than productive on-shore areas, large unexplored areas remain, and there is great potential for reducing bypassed oil in known fields. Much of the remaining oil in the offshore is trapped in formations that are extremely complex due to intrusions of salt domes. Significant innovations have been made in seismic processing and reservoir simulation. In addition, significant advances have been made in deviated and horizontal drilling technologies. Effective application of these technologies along with improved integrated resource management methods offer opportunities to significantly increase Gulf of Mexico production, delay platform abandonments, and preserve access to a substantial remaining oil target for both exploratory drilling and advanced recovery processes. On February 18, 1992, Louisiana State University (the Prime Contractor) with two technical subcontractors, BDM, Inc. and ICF, Inc., began a research program to estimate the potential oil and gas reserve additions that could result from the application of advanced secondary and enhanced oil recovery technologies and the exploitation of undeveloped and attic oil zones in the Gulf of Mexico oil fields that are related to piercement salt domes. This project is a one year continuation of this research and will continue work in reservoir description, extraction processes, and technology transfer. Detailed data will be collected for two previously studied reservoirs: a South Marsh Island reservoir operated by Taylor Energy and a South Pelto reservoir operated by Mobil.
