MAJOR ACHIEVEMENTS

2014

  • Responsible for managing & executing production strategy for the Chestnut Field (FPSO development) through 2014 in a scaling environment as seawater breakthrough occurred on both producing wells. This required maintaining production to maximise revenue through close well performance monitoring while progressing mitigation plans to perform scale inhibition treatments in as cost effective manner as possible in a subsea environment.
  • Production maintained through 2014 to meet production target Scale treatments successfully performed in 2015.

2013

  • Responsible for developing a production strategy document for the Greater Kittiwake Area (GKA) & Trees assets. Formulated guidelines for reservoir pressure management, well performance and highlighted key risks & opportunities into an agreed management plan. Regular meetings to agree priorities and actions were organised and chaired.
  • Responsible for guiding a Mallard (GKA) re-completion through the SOR process including evaluation of additional wellwork through probability analysis. Final technical & economic analysis presented to internal management & partners for approval.

2012

  • Reviewed the failure of a Magnus producing well suspected to be related to sand influx and recommended an intervention plan to reinstate production. Conducted a study of all sand prone wells on Magnus and recommended well operating envelope guidelines to prevent further failures.
  • Outlined study for de-liquification strategies for the Marnock Field. Velocity strings, gas lift and lowering arrival pressure were options investigated through Prosper modelling.

2010-2011

  • Directed the process ofopportunity recognition, objective setting and planning for well coiled tubing intervention campaigns on the Clair and Magnus Fields to maximise recovery.
  • Careful assessment of intervention risk in the mature Magnus field was the main challenge
  • Sand /scale fill problem, ageing completions and stuck plugs / fish meant risk and reward had to be agreed and explicitly presented for management approval.
  • Four well campaign of prioritised wellwork was recommended to maximise operational success

2009

  • Investigated the feasibility and made recommendations for chemical treatments to enhance production in the Erskine & Strathspey maturing assets.
  • Foamers to stimulate liquid loaded wells & incorporate in scale inhibitor squeeze
  • Relative permeability modifiers to shut-off water
  • Treatment to alleviate condensate banking

2008

  • Participated in a Subsurface team to guide several projects for the mature Strathspey Field through the Chevron business planning process.
  • A Brightwater polymer treatment
  • A subsea water shut-off intervention
  • The drilling of a new subsea retro-grade condensate well
  • Field decommissioning planning

2007

  • Participated in a team formed to plan and execute an intervention on an Erskine producing well involving scale clean-out, perforating and a scale inhibition squeeze.
  • HP/HT field with depleted sands, normally unmanned installation (NUI),limited accommodation and deck space all made this a challenging environment to operate.
  • Participated in a Subsurface team to plan & execute a Strathspey subsea rig campaign
  • Scale squeeze and add perforations to a horizontal producer
  • Clean-out and add perforations to a supporting water injector.

2006

  • Devised a scale management strategy for the HP/HT Erskine Field. Scale prediction, dissolution and inhibition were reviewed, laboratory /core work performed and recommendations made as part of the work plans to re-establish and maintain production from the Erskine field.
  • Participated as part of a subsurface technical team to evaluate the use of a pioneering Brightwater polymer treatment on the Strathspey Field. Treatment formulation and execution planning were completed and the treatment successfully performed. Co-authored SPE paper with Chevron research personnel.
  • Provided engineering technical support for the Caledonia Field which included gas lift and pipeline modelling reviews, production forecasting and co-ordination of future development opportunities.

2005

  • Participated as part of a subsurface technical team tasked to plan and execute a £15MM horizontal re-drill as part of the late re-development of the Strathspey Field. Recommending the perforating strategy and well performance prediction were my main responsibilities using Prosper software.

2004

  • Participated in a subsurface technical team to perform a £5MM workover on Strathspey horizontal development well. Scale removal, production logging, wso and perforating options were evaluated and recommended for execution.
  • Co-ordinated a study on the feasibility of a late-life strategy to de-pressurise the Brent Sands in the Strathspey field. Using Chevron research personnel in Houston as a resource it covered reservoir simulation, artificial lift and seabed facility technology. Thecompleted technical report was used to generate project economics and subsequently presented to internal management & partners.

2003

  • Reviewed development options for the low permeability, thinly bedded Perth Field. Presented technical report to management and partners recommending fractured conventional wells over high angle slant wells.
  • Subsurface representative in the drilling and completion planning process of a three well sidetrack campaign using Thru Tubing Rotary Drilling on the Scott Field.

2002

  • Participated in a risk assessment study of Annular Safety Valves in gas lifted wells on the Scott Field.
  • Evaluated the use of a Framo subsea booster pump for enhancement of Scott subsea producers and injectors.

2001

  • Conducted a review of scale management for the Scott and Telford Fields and made recommendations for improvement.
  • Promoted an innovative Production/Injection dual purpose well design incorporating a hydraulic pump for a well candidate on the Scott Field. Feasibility study on design and execution completed.

2000

  • Initiated the first successful “skin by-pass” hydraulic fracturing treatment in the North Sea on the Scott Field with economic payback measured in days. Co-authored subsequent SPE paper and Schlumberger Oilfield Review magazine article.

1999

  • Participated in Schlumberger/Hess Alliance to find improvements in low performing wells on the Scott Field. Hydraulic fracturing candidates, improvement to low productivity wells and artificial lift alternatives were considered and the best ideas executed.

1998

  • Investigated mechanical and chemical methods for successful water isolation on Scott. This included reviewing available mechanical straddle technology and the design and operational planning of two gel water shut-off treatments.

1997

  • Participated in the planning of platform and subsea well interventions in a campaign to remove scale, log and perforate on the Scott Field.
  • Promoted well performance and decision analysis techniques to allow benefits of intervention planning to be clearly quantified and prioritised.
