5th EAGE Passive Seismic Workshop: From Wish List to To-Do List | Year: 2014
Enhanced oil recovery is routinely performed by water flooding in the Tazlau field in Eastern Romania. By the end of 2013, a borehole microseismic feasibility study was launched to gain better understanding of the producing reservoir behavior. Two wells were equipped with 8 geophones in approximately 1000 meters depths in two consecutive periods coinciding with the initiation of the injection phase. In the first well, a significant amount of microseismic events (2566) was recorded during 14 monitoring days, in contrast to a very small number of events (54) observed in the second well in the following 14-day period. This significant difference is related to the varying fracture density in the area and, to a lesser degree, to the amount of injected water. In general, event hypocenters can be located within distances of 600 meters from the monitoring well with sufficient accuracy, and their moment magnitudes range from -1.5 to -3.5. Fracture network characterization based on the microseismic pattern is supported by the analysis of fullbore formation imaging. The study provides new insight on potential water paths. We conclude that borehole microseismic monitoring appears as a promising and useful technique for steering water injection.

The crustal stress pattern of Romania provides key insights into whether the Vrancea slab with its seismogenic volume between 70 and 175 km depth is still coupled to the crust and thus acts as a stress guide, or whether it is already in a state of detachment from the crust. Knowledge of the state of the slab under Vrancea is particularly critical because the slab attached to the crust can result in future strong earthquake occurrence in the crust and even in the currently aseismic zone between 40 km and 70 km depth, potentially causing severe damage. Our analysis of the contemporary tectonic stress observations in the context of potential stress sources and the comparison with numerical modelling shows that the crustal stress pattern in Romania is heterogeneous and does not contain a long wave-length stress pattern that would be expected if there is a strong present-day coupling between the subducted slab and the upper plate, or if lateral plate boundary forces would control the regional stress pattern. Therefore, we conclude that the crustal stress pattern of Romania is characterised by small differential horizontal stresses where local stress sources (third-order effects) are responsible for the observed heterogeneity of stress orientations and that the subducted slab under Vrancea is only weakly coupled to the crust. © 2009 Elsevier B.V.

Oil production from offshore Lebada field has been improved significantly over the last two years through the use of multiple proppant fractures placed from horizontal completions. Following early successes the engineering effort now focuses on increasing value through engineering innovation and increased productivity. This paper describes, through case histories and field data, the advances made in the application of workflow processes, design and execution of these completions. Due to the offshore environment, emphasis is placed on high-efficiency operations based on specially tailored solutions incorporating new workflow processes and technologies. This resulted in a significant impact on operational efficiency by lowering costs and ultimately increasing hydrocarbon production. In the first well candidate, decision was made to complete the horizontal openhole well with a permanent completion system consisting of multiple mechanical packers and ball activated frac ports that would enable multiple fracturing treatments. It was determined that by using a novel viscoelastic polymer-free surfactant-based fluid, the desire fracture geometry could be optimized while being able to mix the fluid on-the-fly with sea water, therefore eliminating the need of re-loading water and materials after each frac job and allowing the excecution of the entire operation in a single trip, avoiding unnecessary vessel trips to shore to reload materials. This novel multistage fracturing system was introduced in Europe for the first time in 2008. Because of this initial success, additional wells were selected and treated using same engineered approach. Two horizontal wells were logged using Wireline Technology and logging while drilling technology, interpreted openhole images and advanced sonic logs were used to determine the optimum completion configuration and to select favorable fracture initiation points and treatment designs. Multistage frac was designed according to the Geological and petrophysical information from log data integration. A vertical well that completed with a limited set of logs and is, in this presentation our blind test well. The openhole packers were placed in sections of the wellbore free of open fractures, contacting shale streaks with higher stress acting as barriers for fracture propagation and providing hydraulic isolation. The frac ports on the other side were placed in the points where the fracture would most likely initiate. Those parts of the wellbore contacting open fracture systems, identified by image logs and sonic logs were expected to show lower stress and lower shale content. Fracturing ports were selectively spaced to provide the best reservoir drainage pattern. Productivity is the driver for economic success and processes and treatment design requirements have evolved through the new techniques implemented, that has now become the standard in Lebada field. Production data on these three wells indicate expected production and demonstrated the full success of the technology utilized. Multi disciplinary approach on all 3 wells has allowed a perfect optimization of completion techniques that has allowed PETROM to save rig time in an expensive offshore environment. Normalized well productivities continue to improve and the challenge is to maintain the rate of evolution through the improved application of both new and existing technologies. © 2010, European Association of Geoscientists and Engineers.

The present day collage of various Silurian basin fragments in Central and Eastern Europe (CEE) is the result of several orogenic and rifting/drifting episodes. The proper paleogeographic reconstruction of a single, very large Silurian foredeep basin in the context of regional geology has a major impact on the ongoing unconventional shale gas exploration efforts in the region, including Poland, Ukraine, Romania and Moldova. The distal segments of a large Silurian foreland basin associated with the Caledonian collisional orogene, along the perimeter of the East European Craton, can be reasonably followed along strike from NW to SE, from Poland all the way to the Ukrainian Black Sea coast. The foredeep basin sequence onlaps to the NE the various pre-Silurian and crystalline basement units. The Silurian basin of the CEE is interpreted here as a pro-foreland basin, with short-lived (less than 15 m.y.) and extremely rapid (locally more than 1,500 m per m.y.!), accelerating subsidence histories recording a portion of the orogenic history of the broader Caledonian orogeny. Besides the typical subsidence curves and the very prominent onlap of successive Silurian lithostratigraphic units onto the craton, the flexural origin is also supported by the general lack of normal-faulting within the basin, contradicting some interpretations suggesting deposition on the extensional continental margin of the Rheic Ocean. The map-view distribution of the lithofacies within the basin, such as clastic turbidites in the southwestern perimeter of the basin, deepwater shales in the center and neritic carbonates on the northeastern foreland margin, is also consistent with the flexural basin interpretation.

An unconformity has been observed along the Black Sea shelf on seismic reflection profiles and wells which is broadly similar to the one associated with that formed during the Messinian salinity crisis (MSC) in the Mediterranean. Therefore, this intra- (or Middle) Pontian unconformity has been traditionally interpreted as the manifestation of the MSC in the Black Sea Basin. However, the magnitude of the sea-level fall associated with this erosive surface does not appear to be nearly as significant as was assumed previously. Also, the inferred MSC surface itself cannot be easily followed into the palaeo-deepwater basin as a regional unconformity in the same manner as in the Mediterranean. Moreover, around the Black Sea, there is no evidence of major river incisions during the MSC, unlike the well-documented cases in the Mediterranean region. If the MSC evaporites in the Mediterranean indeed deposited in a subaerial setting at the basin floor, the lack of a major drawdown in the Black Sea explains why there are no Messinian evaporites in the Black Sea. Owing to the approximately 500 m MSC sea-level drop the Black Sea basin system, this basin did not even get close to the conditions required for the formation of evaporites in the basin centre. As the magnitude of the sea-level drop and the overall impact of the MSC in the Black Sea is interpreted to be less significant than in the Mediterranean, the risk of breaching pre-existing hydrocarbon traps during the MSC is less than has been suggested before. © 2016 The Author(s).

The Levant Basin is a deep-water basin in the eastern Mediterranean region. A large part of the basin contains a characteristic set of closely spaced normal faults, informally called the "piano key faults." These normal faults trending NW-SE have a fairly high-frequency map-view spacing of approximately 3-4 km on average and tens to hundreds of meters of interpreted throw. A large part of the pre-Messinian sedimentary strata is faulted, including the entire Miocene-to-Oligocene sequence. At depth, all the faults consistently die out at the same intra-Eocene detachment level. This stratigraphic level is interpreted to have a regionally developed shale sequence acting as the basal detachment surface for the piano key faults. The amount of throw on the individual faults appears to decrease toward the basin margin and the faults do not extend into the adjacent basins of the broader eastern Mediterranean area. © 2012 Society of Exploration Geophysicists.

Primary and secondary migrations are well defined terms in hydrocarbon reservoir genesis, as spontaneous hydrocarbon displacement from the source rock to the final trap. The fluid movement that occurs after reservoir abandonment defines the tertiary migration process. The result of the tertiary migration is a new saturation distribution within the reservoir and it is expected that in the most favorable cases, the production potential of some parts of the reservoir might be restored. The principles and factors involved in the tertiary migration process are examined and two successful production restarting projects in Romania are presented, as proof of the new concept effectiveness.
