Abcreste Consulting was contracted by TalismanSinopec UK to undertake a review of the potential of the brown field development Tartan field located in the Outer Moray Firth,North Sea.
The Tartan Field is a mature multi pay zone oil field development that has been in production since 1978 using a dilapid
Abcreste Consulting undertook the following activities in completing the project:
Abcreste’s work resulted in full field evaluation that identified a series of infill well opportunities for future growth, it also brought to bare the risks associated with the opportunities.
Talisman acquired a comprehensive field review that was long overdue and provided a basis for it to decide on a desired future
course of action for the entire Claymore/Tartan area in the Outer Moray Firth basin.
Abcreste Consulting ’ consultant was involved in the field review and development planning of the York gas field.
The York gas field is located in the Southern North Sea (SNS) area of the United KingdomContinental Shelf (UKCS). Presence of many intra-faults , particularly the intra-fault located south-west of the field makes the development of the field challenging.
Abcreste Consulting ’ Consultant undertook the following activities in completing the project:
Provided the company with two optimal development options and a flow chart showing the dependence of option two on option one .
Operator drilled wells in the field based on work carried out and FDP submitted by Abcreste Consulting ’ Consultant
The operator put the field to production with production within prognosed rates
VJN Engineering Consultancy UK Limited, along with LR Senergy was contracted by an Oil & Gas Producing Company operating in Caspian Sea to investigate the potential for water hammer effect emanating from abrupt valve closure during water injection.
The study also evaluated the potential for sand production in producer wells along with determining minimum flowrates for optimal production with minimal solids production and transportation.
The study performed by VJN & LR Senergy has resulted in identifying possible sand deposition locations essential for pigging operation. Best practises for valve closure have also been advised.
The study also provided an avenue for a subsurface/subsea multi-disciplinary collaboration, where expertise from both fields provided the client with an optimum solution.
Abcreste Consulting ’ was mandated by Sonangol to carry out an independent review on the economic feasibility in doing a Cross Block Development between 2 Ultra deep offshore blocks (block 16 &3 1)
Both blocks had 16 associated oil and gas fields were located offshore Angola and the two different operators had been unable to make the economics stack up. As a result the developments were declared contingent and shelved. Sonangol in a bid to move things forward wanted an independent view on the commerciality of a cross block development to keep the CAPEX down and restart conversations.
Abcreste Consulting undertook the following activities in completing the project:
Provided the company with an optimal phased development option, delaying upfront CAPEX by $700m and CAPEX savings up to $2 billion
Study results proved that development could break even at much lower oil prices (<$30/bbl savings)
Sonangol was more informed in reviewing IOC’s request to adjust PSC terms to favour their blk 31 and blk 16 standalone development concepts
A more detailed FDP was initiated amongst the contractor group as a result of ZAIL study
