ION extends 2D seismic off Panama

Written by

ION Geophysical announced an approximate 50% extension to its previously announced program offshore Panama due to strong client interest and prefunding to evaluate offshore Panama in advance of the anticipated license round.

The client-driven survey provides a regional framework typical of BasinSPAN programs to evaluate the geology of the Panamanian offshore, while the new extension provides more detailed coverage that will allow E&P companies to evaluate blocks ahead of the expected license round.

Recent exploration success offshore Colombia, adjacent to Panama's Caribbean coast, has created interest among E&P companies in high-quality seismic data to evaluate the hydrocarbon prospectivity on this margin. The expanded program will be approximately 9000km and is the only modern data available offshore Panama.

Brian Hanson, ION's president and CEO, said that the geophysical firm utilized a new software tool called Marlin, which enabled ION to navigate the busiest maritime transit route, near the Panama Canal, which allowed for a safer and more efficient program. 

"Akin to modern air traffic control systems, Marlin integrates a variety of real-time data sources that enables multiple stakeholders to share and visualize vessel route plans, foresee and avoid conflicts between vessels and fixed assets, optimize schedules, and measure and improve asset performance. Marlin enables greater collaboration allowing underwriters to tune into what's happening in the field real-time from their offices to monitor program progress and key statistics," Hanson said.

The first deployment of MaMPU 1 will be at Anjung Kecil oil field, offshore Sarawak, which is currently being operated by Vestigo Petroleum Sdn. Bhd. on behalf of Petronas Carigali Sdn. Bhd.

MaMPU 1 was converted from an oil tanker and has a storage capacity of 318,000 bbl, designed to produce 15,000 b/d with 25 MMscf/d of gas handling capacity. One transformation technology that MISC has adapted on MaMPU 1 is Sep-iSYS, a compact low pressure system that stabilizes the crude received from the reservoir for safe storage and subsequent export to the market.

Through its condensate recovery system (CRS), MaMPU 1 is designed for increased oil production via recovery from unwanted flaring gas. CRS, combined with Sep-iSYS will enable the production of an additional 50 bbl per 1 MMscf of flared gas.

In line with MISC’s initiatives to reduce carbon footprint for gas emissions, it is expected that the CRS will contribute to lowering CO2 emission by 25% to 30% on daily flaring rates. This is consistent with MISC’s mission to operate responsibly and proactively minimizing its impact on the environment where possible, the company said.

MISC is the first in the region to introduce the technologies on a floating asset. This advancement will benefit in sustaining MISC’s position as the one of the leading marginal fields solutions providers.

Premier drops Bagpuss heavy oil field

Written by

UK independent Premier Oil is resigning as operator on the UK North Sea Bagpuss joint venture effective at the end of this year. 

Premier will also sell its 40.1% interest to newly formed firm, Aberdeen-based Reach Halibut, subject to approval by the joint venture partners, says one of the partners, North Sea Energy.

Premier announced drilling results from the Bagpuss well last month. The well, 13/25-1, was drilled using the Ocean Valiant semisubmersible drilling rig on the Halibut Horst in the Outer Moray Firth, in the North Sea.

The well encountered 41ft of hydrocarbon-bearing sands within a 68ft hydrocarbon column, which Premier Oil said was in line with its pre-drill estimates. 

Analysts FirstEnergy said the volumetrics were in line with pre-drill expectations. "As anticipated this is heavy oil, however, the bottom oil temperature was at the lower end of expectations and as a result, oil will be less mobile than initially hoped for," said FirstEnergy. "‎Further tests will be required to assess oil mobility which is the key challenge to get a handle on commerciality."

Back in 2013, when Premier farmed into the Bagpuss acreage, its analysis of the 1981 discovery well result, which was not cored or tested, suggested that the Bagpuss and the nearby Blofeld heavy oil prospects together could contain up to 2 billion bbl in place. Wood Mackenzie has said a discovery here could open up a new play. 

Robin Allan, Director of Exploration and North Sea at Premier Oil, said: “The Bagpuss well has proven a significant volume of oil in place. We will now work with our partners to carry out a full analysis of the hydrocarbons and reservoir encountered to ascertain whether commerciality can be established.”

The joint venture partners in the Bagpuss prospect at that time were Maersk Oil UK (25%), NSE (15%), Premier Oil (40.1%), EnCounter Oil (13.27%) and Groliffe (6.63%).

Reach Halibut was incorporated in July this year. Directors at the firm are North Sea explorers Miles Newman and Canadian Laurence Kinch. Kinch is also a director on Aurora Petroleum.

Skipper well turns up heavy oil

Written by

Initial results from the Skipper appraisal well in the UK North Sea have shown oil "significantly" heavier than expected, but in sands with higher permeability than thought.

Operator and 100% owner Independent Oil and Gas says it will now review its development strategy for the field, which is in Block 9/21a in license P1609.

The firm said of the well results: "Although the oil is moving in the reservoir, the first sample results indicate that the oil is approximately 11° API and has a significantly higher viscosity than expected.

"These measurements do not align with our observations and therefore the remaining samples need to be reviewed and tested. Next steps will then be Reservoir modelling to consider potential development options. Determining commerciality may therefore take several months."

While the oil is heavier than expected, permeability through the reservoir sands is better than expected, at more than 10 Darcies.

The firm also thinks there's more oil in place than previously thought, due to the crest of the Skipper reservoir in the appraisal well being found to be 44ft shallower than prognosed. This has meant the firm's estimate of the most likely oil in place has increased from 136.5 MMbbl to 142.6 MMbbl. 

Mark Routh, CEO of IOG commented: "The analysis of the oil retrieved from the appraisal well indicates that Skipper is a heavy oil discovery with similar gravity to other nearby heavy oil fields.  We have observed that the oil moves in the reservoir and is mobile at surface at ambient conditions. The initial oil analysis results are incompatible with our observations, therefore we are now reviewing our strategy to establish the commerciality of Skipper. In addition, we have an increased oil in place, higher observed reservoir permeabilities and an increased reservoir height from the crest to the oil water contact."

The well was the firm's first as operator.

Dresser-Rand delivers Appomattox power gen equipment

Written by

Dresser-Rand, part of Siemens Power and Gas Division, recently delivered power generation equipment for a combined cycle power plant (CCPP) for the Shell Appomattox deepwater oil and gas floating production platform. The platform will be located 80mi off the coast of Louisiana in the Gulf of Mexico and is slated to start production around the end of this decade. The ~150MW CCPP will feature four 27MW gas turbine-driven generator sets equipped with heat recovery systems and a 40MW steam turbine generator.

The gas turbine gen-sets are self-contained mini-modules complete with all electrical wiring, piping, tubing and controls. The gen-set, ancillary equipment and baseplate remain connected after unit testing, substantially reducing the time required to install, commission and start-up the packages.

With CCPPs, a gas turbine generator produces electricity while the waste heat from the gas turbine is used to make steam to generate additional electricity via a steam turbine. The CCPP for the Shell Appomattox platform will improve overall fuel efficiency, reduce emissions of greenhouse gases, and increase total power generation for the platform.

The packages feature a compact design and reduced weight to accommodate the platform’s footprint constraints. The design allows for easy accessibility to the package components for maintenance and service, along with adequate workspace.

The steam turbine generator package was manufactured in Wellsville, NY and packaged in Olean, NY. An 18.5MW load test was performed on the steam turbine generator set using the steam-producing capability at the Olean facility. The gas turbine generator packages were designed in Kongsberg, Norway.
