Well Testing

Well Testing

Well testing is commonly the last task to be planned in an exploration project. Often this leads to the design and execution being carried out in a rush by personnel for whom testing is not their main focus and awareness of all stakeholder needs may be limited. This can result in objectives not being clearly defined, money not spent wisely and potential loss of very significant data needed to evaluate development cases.

OPC well testing experience covers all possible well types; horizontal and vertical, oil and gas, HPHT, in both onshore and offshore (shallow and deep-water) locations globally. OPCs experience and service offering includes:

  • Well test planning and design (including DST and surface equipment)
  • Service Company tendering and contracting
  • On site well test supervision
  • Well test interpretation (on site and post-test)
  • Well testing operations and well test interpretation training
  • Reservoir surveillance including analysis of data from permanent down-hole gauges

Our Fully Integrated Testing (FIT) Solutions incorporates all of the above.

OPC expert consultants can also be seconded into your organisation on short, medium or long term assignments in order to provide you with dedicated well testing expertise.  OPC has a significant pool of highly experienced well test engineers and well test supervisors and managers who can be mobilised at short notice to support your business.

OPC Directors Piers Johnson and Bill Roberts are active participants in the global well testing community and frequently give presentations to groups including the Well testing network.  We are grateful to Fiona Curley, organiser of the well testing network for this piece of feedback on their knowledge:

OPC have consistently provided  practical, pragmatic and professional analysis presentations at our Welltesting Network meetings and can always be relied upon to provide challenge and support to interpretation and analysis problems discussed at our meetings.

Their experience with all analysis software packages and awareness of the regional variation in service company capabilities helps them consistently provide robust technically justified analysis advice.

Their wealth of knowledge and experience is invaluable; we have yet to find a well test interpretation topic that Piers and Bill haven’t been able to expertly present to WTN members.

If you are organising an event and would like an expert presenter on well testing, please contact Piers Johnson on +44 20 7428 1111.
