Surface Casing Vent Flow and Gas Migration 

REQUEST FOR PROPOSAL (RFP) SGRC-1501

Petroleum Technology Alliance Canada (PTAC) invites you to respond to the subject RFP by submitting a proposal to PTAC no later than September 18th, 2015. PTAC encourages potential project suppliers that can meet a portion of the need outlined in this RFP to make integrated proposals with appropriate co-suppliers.

This RFP has been formulated with input from the PTAC facilitated Soil and Groundwater Research Committee (SGRC) and is a priority for the Western Canadian upstream oil and gas industry. Projects will be funded through the 2015 Alberta Upstream Petroleum Research Fund Program (AUPRF). Projects results must be applicable to Alberta oil and gas operations.

PTAC is an association that facilitates innovation, collaborative research, and technology development, demonstration and deployment for a responsible Western Canadian upstream hydrocarbon energy industry. PTAC’s objective is to improve the industry’s financial, environmental and safety performance through the application of new technology and research. PTAC utilizes a collaborative approach with input from industry and government technical experts for project direction and oversight.

BACKGROUND

The SGRC is soliciting proposals that assess soil and groundwater risks due to wellbore Surface Casing Vent Flows (SCVF) and/or Gas Migration (GM).

Please note that the funding amount to be allocated to address this knowledge gaps is $25K.

PURPOSE

Several operators have started to investigate the impacts and HSE risks of wellbore SCVF and/or GM issues. This is an opportunity to pool resources and investigate the potential impacts/risks to receptors due to SCVF/GM from the subsurface into groundwater and soils. The following outlines Phase I of a potential multiphase project:

  1. Engaging abandonment experts to determine:
  • What types of SCVF/GM exist,
  • When and when not to remediate due to safety concerns,
  • What types of passive and active intervention methods exist (e.g. monitoring, re-abandonment),
  • What identified natural sources of GM have been identified in literature or by industry, and
  • What is the rate and frequency of gas dissipation of SCVF/GM without intervention or repair.
  1. Reviewing literature on SCVF/GM work and environmental risks focusing on the information above
  2. Interviewing experts within Industry (some operators are already active in this space)
  3. Collecting SCVF/GM case studies
  4. Categorizing non-safety related case studies based on:
  • Abandonment knowledge (e.g. flow, depth of leak)
  • Environmental impact (e.g. vegetation, soil, groundwater)
  • Economic impact (e.g. potential costs of intervention)

Summary report

PROCESS

PTAC, with financial and technical support from industry and government, intends to utilize the following process to launch this project.

The competition will close on September 18th, 2015. All proposals must be received by this time.

The successful applicant will be selected and notified by PTAC no later than October 5, 2015.

Project proposals will be kept confidential to the SGRC for the duration of the competition. Project results will be shared with the funding partners with facilitation provided by PTAC. PTAC will not screen, evaluate or influence the selection of potential suppliers.
