IESL has been awarded work by Venture production to develop and implement a sand management programme for one of their UKCS fields. Working with Venture engineers and contractors the programme will develop and implement strategies and technical/operational guidelines to manage daily field operations for solids production, well pressures and process maintenance.

IESL is publishing recently completed work at the SPE Formation Damage Conference to be held in Scheveningen, The Netherlands in June 2009. The paper based on IESL's well productivity systems is entitled “An inflow prediction model for open hole gravel pack and frac & pack completions” it allows prediction of the flow impairment of gravel pack completions as a result of damaging mechanisms and reservoir contribution changes. See our publications page and Links to have access to the paper.

IESL has completed wellbore stability work for Centrica UK for their new Irish Sea drilling programme, the well is to be drilled in a partially depleted area of the field. This work took advantage of large data sets and results of ongoing projects developed by IESL in this area. They include rock strength testing using IESL Rapid Low Impact Strength Test RLIST " method that allows mechanical characterization of the various formations. Dynamic OMW and hydraulic parameters were optimised to allow safe and effective drilling of the well.

IESL has completed another successful project for a gas storage project in the Irish Sea. The study covered the wellbore stability and sanding risk analysis for the Bains field, which will be re-developed as a gas storage by Centrica. Pressure cycling and current depletion effects were some of the biggest challenges encountered during this work.

IESL has been awarded geomechanical work for Gabon. Working along with Axis engineers the project will deliver an optimised sand face completion design for Bowleven Gabon subsidiary

Venture production has awarded IESL work for the development of the Optimum sand face completion design for one of its gas assets. The work involved shallow gas prospects in the UKCS, geomechanical and production models were developed for the reservoir and the optimum sand face completion identified successfully.

IESL will be exhibiting its products and services at INGEPET, one of the leading technical conferences in Latin America which this year is being held in Lima, Peru from the 12 to the 16 of October. Our operations in Latin America are very successful with offices in Valencia, Venezuela and servicing customers in Peru, Trinidad and Venezuela.

Gas storage reservoirs are submitted to pressure cycling throughout the year as part of its operating function. IESL completed work on the design of the optimum sand face completion for a sandstone reservoir in mainland Europe. A number of completion options were evaluated using a number of analytical models in order to select the optimum solution for such a demanding application

IESL has completed wellbore stability work for highly fractured carbonates in the Middle East. The results involved the utilization of advanced geomechanical models to predict the optimum mud weight envelop considering very long fractured interval through the well path.

IESL has been working in developing technology for gravel packed completions for a number of years. Our CleanPAQ system was the first result of it and now we have concluded work on a system to predict filter media inflow. This development will allow our customers to predict GP performance based on the quality of the reservoir, mud system and completion practices.

IESL and Axis continue to work successfully in a number of projects. IESL’s geomechanical expertise integrated into Axis’s vast well testing and completion experience has resulted in new work for clients in Thailand, The Netherlands and the Middle East.

Pluspetrol Peru has awarded work to IESL for the continuous development of their large Geomechanical system, The Custodian. The work involves extending the system to cover two additional fields which will be characterized completely and the geomechanical model for each one developed. It follows the continuous success obtained with the current system that is currently being used for a variety of geomechanical applications

IESL and PDVSA engineers have completed perforating design work for their high rate gas wells offshore Venezuela. The work involved the determination of the optimum underbalance conditions for perforating as well as gun performance prediction using IESL methodology GeoPerforation which has been so successfully implemented in other areas particularly the North Sea.

IESL was awarded the development of a Knowledge Transfer module for the M.Sc. program of the Universidad Bolivariana de Venezuela - UBV in Maturin, Estado Monagas. The program in well completion and sand control was very successful and had 24 participants. This is the first overseas academic success for IESL which has had a 10 years successful association with the Robert Gordon University in Aberdeen.

Talisman Energy has awarded IESL work to develop formation mechanical properties profiles and identify potential sources of formation damage. Based on IESL’s GeoPerforation” system and the successful results obtained on both Blane and Clyde fields, Talisman expects to optimise its perforation design strategies to ensure maximum well production and injection in their fields.

IESL has been awarded work by PDVSA to identify the challenges for development of the Ceuta field in Lake Maracaibo, Venezuela. The work involves working with PDVSA’s engineers to review completion performance in the field known as one of the more demanding in Occidente due to its difficult geomechanical settings. IESL will develop along with PDVSA enginieers technical solutions to their current designs.

Talisman Energy has awarded IESL work to carry out rock strength testing on core material from the Clyde field. Based on a rapidly growing and very succesful testing record with over 1500 feet of core test in the last 18 months IESL will test the existing core on site in order to build geomechanical models for the field.

IESL and Pluspetrol Peru have published detailed work on formation strength determination for water injection wells. The paper was presented at the Society of Petroleum Engineers conference in Rome, Italy that was held on the 10 – 14 of June. The paper presented describes the results from a large laboratory program and simulation work to determine the effect of thermal changes on rock strength. The paper can be downloaded from the SPE site, paper No. 113 825.

IESL and Axis Technologies have completed asset optimization work for Pluspetrol Peru. The work involved working with Pluspetrol engineers in developing well and pipeline network models for two(2) fields in Northern Peru. The results will allow the customer to remove the bottlenecks in the system and ensure maximum productivity for the fields.

IESL has achieved a milestone of over 1500 feet of testing record carried out using a non-destructive unconfined strength test method. The tests completed for wellbore stability, completion and perforating design applications have been carried out in Norway, Venezuela, Peru and the UK. This technique has simplified the data acquisition and quality for strength testing and contribute to deliver csot effective, faster and better quality work for our customers

IESL has been awarded work by PDVSA to develop sand face completion designs for their Guafita field in Southern Venezuela. The work involves working with PDVSA’s engineers to review completion performance in the area and develop technical solutions to their current designs.

Venture Production has awarded IESL sand face completion design for their new producer in the Chestnut field. Based on over 8 years of work in the field IESL has developed a unique expertise and understanding of the field to continue working with Venture engineers to deliver maximum cost effective productivity from the field.

Pluspetrol has awarded IESL the production optimization work for their Shiviyacu and Carmen fields in block 1AB. The work involves working with Pluspetrol engineers in developing field and network performance models and carrying out simulations to establish areas for potential optimization. This work follows the successful completion last year of the Capahuari field work.
