Transcript: Directional drilling is the science of deviating a well bore along a planned path to a target located a given lateral distance and direction from vertical. Surface casing - protect aquifer 3. What are the Problems of Conventional Casing While Directional Drilling? Casing is an important assembly in drilling engineering which is fixed by cementing. There are different kinds of casing acting different role while drilling. Problems Caused by Absence of Directional Casing Directional Casing Technology While Drilling Intermediate casing - prevent blowout Schlumberger Service and Products http://www.slb.com/services/drilling/directional_drilling.aspx?entry=ad_google_dm&gclid=CKmqofmXyLMCFcsWMgod8CQA_A Directional Casing While Drilling http://www.slb.com/services/drilling/specialty_drilling_applications/casing_drilling/directional_casing.aspx Definition of Directional Drilling Directional Drilling Directional Drilling is Getting Popular Nowadays Method Reasons We Use Casing While Drilling with an Inclination, the Forces on Different Side of the Wellbore are Different Due to the Depth Diefferent The Well Bore is not Perpendicular to Ground, so the Cuttings are more likely to Settle at One Side of the Wellbore If no Directional Casing is Applied to Wellbore, Problem such as Lost Circulation and Wellbore Instability will Occur 2. Why We Use Casing? aquafer Conductor Pipe - prevent from caving in 1. What is Directional Drilling? Adventages with Rotary Steerable System 3/4 of the Wells Drilled Last Week are not Vertical Tools PowerDrive X6 push-the-bit Rotary Steerable System or PowerDrive Xceed point-the-bit Rotary Steerable System Directional Casing while Drilling uses the Rotary Steerable System (RSS) Reference 4. What Tools and Methods can be Used to Solve the Problems? Method and Tools Production casing - help produce oil efficiently Constant casing rotation breaks static friction which create even WOB Facilitates borehole cleaning by moving drill cuttings into flowstream Directional and inclination control is much easier with a rotary steerable system (RSS) which resulting in smoother borehole trajectory

It consists of Crown Block, Derrick, Traveling Block, Drilling Line and Drawworks 3. Intermediate casing Offshore Rigs Rotary drilling has been in use as early as 3,000 B.C. in China, and later in Egypt. The concept of rotary drilling has evolved and grown over time. Leonardo da Vinci created a design for a rotary drill in the early 1500s; it closely resembled the rotary drilling method employed today Types of the drilling fluids : Casing a well Source :NARBORS CO. Water base mud Submersible rigs When is it used ? Types of samples Run by : Slick line though tubing or casing string or on drill pipe string Depth penetration : exceeding 50 inch Advantages : 1. Carries more TNT 2. Large no. of shoots 3. Better phasing 4. Deeper penetration 5. Doesn't leave debris 6. Used in tight formation Disadvantages : Expensive Coring bit : 1. Usually PDC or diamond 2.

Quick Overview 1. Retrievable 2. Permanent Importance Why do they matter? - Main component in regards to completions - Can be used as a way to separate multiple producing zones - Facilitates artificial lift - Protects casing from high pressure and corrosion. -Essential for most wells to function properly How it Works Key Components Body/Mandrel wedge-shaped device with teeth used to penetrate and grip the casing wall Slip beveled to match the slip and forms ramp to drive slip outward into casing wall Cone Packing Element System creates seal between packer and inside diameter of casing Configuration Types Various types and configurations for different wellbore or reservoir conditions Each type is run down hole with production tubing string or a wire-line The purpose is never to restrict normal production or injection flow Rating Envelope Must be able to hold differential pressures at varying temperatures Rating Envelope Rating envelope shows the safe operational limits Cost Downward trend in prices due to small demand and high competition Retrievable packers cost more than permanent packers Range from 6,000-300,000 USD Cost “Packers & Plugs.” Daleel Supply Chain Management Network, www.scmdaleel.com/category/packers-amp-plugs/152. “Oil 101 - Well Completion - Upstream Oil and Gas.” EKT Interactive, www.ektinteractive.com/production/well-completion/. “Packer.” HHP - Schlumberger Oilfield Glossary, www.glossary.oilfield.slb.com/en/Terms/p/packer.aspx. “Packers.” Functions of Drilling Fluid -, petrowiki.org/Packers.
