From Placement to Monitoring of Horizontal Wells

Highly deviated or horizontal wells are becoming a very important part of field development strategies in particular in reservoirs where vertical wells have low productivity; shale gas, water contact proximity, heavy oil, or naturally fractured. Evaluation, placement and monitoring of high angle and horizontal wells remain challenging due to the complexity of the measurements recorded and the inherent challenges posed by targeted reservoirs. Landing, steering and producing a high angle well requires significant planning, evaluation and monitoring. It involves more than one domain of activities such as geological and geomechanical control, log and reservoir modeling, formation evaluation, production and reservoir monitoring. Advances in mud logging, coring, and logging measurements provide key input to execute and evaluate these wells. Log evaluation is peculiar in horizontal wells as compared to vertical wells. The measurements are not perpendicular but sub-parallel to the layering, and therefore modeling even the most basic logs is often required to infer petrophysical properties. It forces petrophysicists to go beyond the 1D well-line description of the reservoir, and opens a completely new and exciting way of evaluating formations as it provides an additional dimension to 3D reservoir models

Topics associated with high angle and horizontal wells include:

  • Geomechanics: Wellbore stability, placing hydraulic fractures, 3D geomechanics
  • Well placement and geosteering: mud logging, geochemical characterization, MWD/LWD and seismic guided geological control.
  • Petrophysical evaluation and uncertainty analysis: Horizontal well core and log analyses in clastics, carbonates, naturally fractured, shale and tight gas, heavy oil reservoirs
  • Completion designs, production and reservoir monitoring: Petrophysics for designing ICD, production logging and time lapse techniques.

8.00 am to 9.00 am: Registration
9.00 am to 3.00 pm :

Real Time (RT) interpretation of LWD measurements – Focusing on Resistivity measurements in horizontal wells

Why do Induction and laterolog provide different resistivity values in a horizontal well? Is the difference due invasion, anisotropy, shoulder bed effects, polarization horns, or is the tools simply being run out of spec? Which measure can be used for Rt? How do different measurements affect the calculation of Sw? Does Sw determination matter in a horizontal wells?

How to deal with conflicting data?

Where is the well within the specified target? Is GR the only measurement needed when it comes to geosteering, or are other measurements required? Is unique solution even possible when it comes to understanding the results from horizontal well with respect to the geological earth model?

Strategies to mitigating risk from uncertainties.

What uncertainties can possible exist when planning and executing horizontal drilling projects in a developed field with excellent seismic? How can risk from uncertainties be determined in advance of drilling? What role does pre-job geosteering modeling have in evaluating risks and in selecting the best method, measurement, and tools for geosteering? Can all risks be eliminated if all known services are utilized when drilling a horizontal well?

Incorporating interpretation back into the earth model

After drilling a horizontal well, what can be done with the data, and how can this data be used to improve the earth model? In this topic, single point, multi point and ribbon surface updates will be discussed when it comes to incorporating RT data into the geological models. 7.00 pm – 9.00 pm: Registrations and Ice Breaker with Dinner: Welcome from SPWLA Kuwait Chapter

Chairman's report

From Placement to Monitoring of Horizontal Wells

The Regency Hotel & Resorts, Kuwait

Monday October 28th
I had the privilege of attending the 2nd annual Topical Conference in Kuwait at the end of October 2013. The conference started off with a one-day short course-workshop  on the Petrophysicists' role in the risk analysis and interpretation of Horizontal wells. Stan Ingham with Schlumberger covered a broad range of topics moving from the Real Time interpretation of LWD measurements through dealing with conflicting data and mitigating the uncertainties involved so that the data and interpretation can be suitably inserted back into the field wide earth model. Stan is a dynamic speaker and set the stage for the next three days of presentations.


Note: Stan did an excellent job in presentation but the full scope of material was a little overwhelming to absorb over a single day.
Registration continued and the Ice Breaker was held Monday evening. The event was highly successful with food and drink that would befit royalty.
Tuesday October 29th


The Conference was officially opened by Mr. Hashim S. Hashim, the KOC CEO and Mr. Salem Al-Sabea the SPWLA-Kuwait chapter president. The conference introduction was then presented by Elton Frost Jr., the President of the International SPWLA society.
After a short break, a series of presentations were made of Well planning, location design, risk analysis and multilateral implementation. Key factors to success included:

  1. Need for a multidisciplinary team
  2. Upfront design and conceptualization is key
  3. Emphasis on drilling process safety and design with Best Practices learned
  4. A holistic approach is mandatory (All logs / Seismic) to resolve geological ambiguities

The session provided an excellent mix of best practices learned coupled with real life examples of drilling programs in both carbonates and clastics.
In the afternoon, we moved on to aspects of Geomechanics. Three talks were provided on the role of Geomechanics in HA/HZ holes.
Wednesday October 30th


Day 2 started off with talks on Mud logging and Geosteering. This included discussions on the use of mud logging to supplement the LWD services and the use of new near-bit technology in guiding the well path. Geosteering examples were provided along with Case historys of geosteering in channel sands and long laterals in a very thin sand reservoir. This session rounded out with the use of Seismic modeling in geosteering and well placement.


Note: In almost all discussions, considerable time was spent on the need to use Seismic, but we still need a way to properly bridge the gap of well scale vs. Seismic scale resolution and the questions of depth/time conversion to fully integrate the system.


The afternoon focused on LWD in formation evaluation.  This included the many options now available for LWD and how we have narrowed the gap between the capabilities while drilling and wireline. What is still outstanding is the consistent use of HZ data in terms of petrophysical parameters that can be directly fed into reservoir models.
Note: We are still in the early days of deriving meaningful petrophysical parameters from HZ data that are comparable to those derived from more conventional vertical wells. This will only be mitigated with improvements in tool response modeling and a better definition of the differences between vertical and horizontal flow characteristics.
Thursday October 31st


The morning continued with LWD applications and covered integrated petrophysical solutions as well as discussion on source less measurements  and fracture characterization using LWD devices.
The last topic in the conference was the section on Completion and Production monitoring. This really hit on the meat of the problem of supplying the proper information for ICD design and what happens when things do not go according to plan. While ICD's have been highly successful, there are times when production does not match expectations and diagnostics are in order.
Note: One of the key parameters needed for a good ICD design is permeability and this is the least understood petrophysical parameter. In long laterals it is possible to get spotted measurements of mobility from LWD formation test tools. In general, however, it is necessary to use the other LWD measurements to form a mathematical transform to cover the whole well interval. Such estimates are typically reasonable but often are not accurate enough to fully maximize the production of the wells.

General


All in all, I think this was an excellent conference. The audience was attentive and interested although a little mobile on attendance. I think that the one thing that may help would be to decrease the depth of the room so that the slides are more visible to those in the rear of the meeting.
The venue was great. The food and refreshments were great. I think I left Kuwait with a few extra pounds.
I think the technical program turned out quite well with the mix of actual real life examples and sharing of best practices being at the forefront. This supplemented with the vendor discussions on technology applications made the conference one that I left feeling that I had new insights and a new appreciation for the challenges in Kuwait for HA/HZ wells.
I want to thank the members of the Kuwait chapter for letting me attend and look forward to the next conference. I hope to see all at the International Symposium in Abu Dhabi in May of 2014.
