Talisman Energy Inc.

Project: Optimization Design of a 3-well pad Multi-stage Frac Horizontal Wells (MFHW) – Cardium formation

Sensitivity analysis was performed with the objective of determining the optimum Hz well spacing and also the frac design; including the frac size and the number of frac stages. Production forecasts were generating using the Rubis Software for various design options. Further, a production acceleration scenario was evaluated to determine its impact on the project's NPV.

Project: Well Performance Evaluation

During the frac operation, 4 stages out of 13 failed as a result of frac-port malfunction. The purpose of this analysis was to quantify the well upside potential should a successful frac treatment is performed on a new Hz well. To create a reliable well model, the reservoir parameters were obtained from the initial flow/build-up test (Saphir software). Consequently, the well production forecast analysis was performed using both the Topaze and further refined using a numerical model (Rubis).

Taqa North LTD.

Project: Evaluation of Multi-stage Frac Hz Well (MFHW) Evaluation

Numerical modeling; using the Rubis software (KAPPA), was used to illustrate the benefits of applying the Multi-stage fracing to an existing Hz well producing from the Red Rock Oil field – Chinook Formation. A multi-layered/multi phase model was generated to account for the two rock types; Conglomerate and sand. The model predict an oil production rate increase of 4 folds for a six-stage frac (open hole completion).

Project: Design of a new waterflood project – Red Rock

Since this field has been on primary production, the expected ultimate oil recovery was not attractive because of the low formation permeability of the Chinook Formation. Based on analytical techniques, it was concluded that the primary recovery factor of approx. 5% could be increased to 20%. The prize of implementing the waterrflood would add additional oil reserves over 15 MMBbl's. A pilot project was recommended to utilize a new MFHW as an injector and existing offset vertical wells as producers. The selection criteria of the pilot location and performance were determined using a combination of analytical and numerical techniques. Based on the results of the pilot project, further decisions will be made to implement a full scale waterflood project.

  • AORC Oil and Gas Ltd.
  • Connacher Oil and Gas Ltd (Pelisko Formation)
  • Petro Bakken (Bakken Fprmation)

Project:

As part of the ERCB requirements for steam injection in heavy oil fields, several Mini Fracs are performed to determine the formation breakdown (frac) pressure. Mini frac analysis has been performed (Saphir software) on numerous wells to satisfy the Board requirement and also to obtain formation parameters critical to fracture treatment design including: closure pressure, leak-off coefficient, formation permeability, etc.

Project: Evaluation of Completion Techniques for MFHW: Valhalla North – Saxsmith (Montney)

Performance comparison of MFHW's using either open hole (Packer Plus Type) and cased hole was performed. Numerical Production Analysis (Topaz Software) was conducted to evaluate the effectiveness of the completion/frac techniques used for the existing five horizontal wells. Further, sensitivity analysis was also conducted to optimize the completion and frac design for newly drilled MFHW.
