Session 1: Economics

Session Chairs : Mamdouh Mahfouz and Ricky J. Bohannon

In our industry today, the key elements are economic which do not start or end with cost. The elements of economics include Well Feasibility, Proper Contracts and Insurance, Risk and Mitigation and Logistics. From the design, contract negotiations, well spud in, to the tie-in to the production facilities, several areas could be investigated for cost optimization. The engineer endeavors to study possible solutions to bring the cost of the well down, which will always include the risk analysis and how he can mitigate these risks in a safe and cost effective manner.

Despite the fact that technology is normally expensive, if rationally applied, it will definitely save money by selecting the right skills, equipment and material which will enhance performance and consequently save time and cost. Innovative drilling concepts, drilling without damaging reservoirs, drilling and completing wells with zero loss time, are all contributing factors to achieve good and economically drilled wells. In deep wells the need to consider economics in well construction is much more as deep wells are usually associated with more difficult scenarios and costly solutions.

Session 2: Well Planning

Session Chairs : Essam Fattah and Said Zaki

Planning Deep Wells Drilling is the big challenge to economically drill and complete deep wells. Reducing the cost of deep drilling will require that we reduce the time it takes to safely drill a well, as the depth of the hole increases, control over well bore trajectory and the placement of casing become increasingly difficult, as does the efficient removal of drill cuttings. The difficulty of cementing wells increases with depth, not only due to the increased potential for poor mud displacement and lost circulation, but also due to the effects of higher temperature on cement setting behavior. The cost of drilling and completing deep wells rises with the increase in the number and frequency of drilling problems and the increasing length of time it takes to correct them. But costs also are greater simply because of the physical requirements of a deep well. Deeper holes require longer drill strings and longer casing strings and thus require rigs rated to support such weights. These rigs are large and expensive, and only a limited number are available, increasing their cost. The result is that in very deep wells, drilling the last 10 percent of the hole can consume as much as 50 percent of the total drilling cost.

Session 3: Applied Technologies

Session Chairs : Ashraf Rafail and Khaled Fawzi

"Capillary and Renaissance System" will provide an permanent downhole chemical injection line through and below the sub surface safety valve (if installed) directly across from the perforations downhole or at the end of the production tubing, where previously they had not be able to do so. The following are the main problems that can be solved using this new system:

• Liquid loading problems for Gas Wells
• Wells that require permanent Injection Line (Foaming, Scale/Paraffin/Corrosion Inhibitor, fresh water, Solvent, Chemicals …etc) that was not initially installed with or without the presence of a SCSSSV.
• Damaged, Blocked or Leaking Control Lines for the Surface Controlled Safety Valves. This is a new Surface Control Safety Valve to be run with a new Control Line.
• Damaged Seal Bores in existing Tubing Retrievable Safety Valves and Wireline Safety Valve Landing Nipples. This is a new Hydraulic actuated Surface Control Safety Valve with integral hydraulic pack-off.
• Wells without a Surface Controlled Subsurface Safety Valve (SCSSSV) that now require one (in the event of a change in regulations or company policy). This is a new Hydraulic actuated Safety Valve that can be set at any depth inside the tubing with no need for Nipple profile or existing Control Line. All the above application will be done for existing wells with no need for a Rig (Rigless Operation)

Session 4: Case Histories

Session Chairs : Osama El Bakhly & Omar Husaini

Case histories are often a rich learning reservoir full of opportunities that can be captured from the operators, contractors and service companies past experience. This session is an opportunity to bring to surface all of these past experiences to build on their successes and to learn and prevent similar failures. Learning from the past and from others will with no doubt enhance our Deep well drilling experience, this venue will bring the past and people experience together to maximize the learning. This session will allow presenters to address all aspects of Deep well drilling from past experiences and to share them will the attendees.
