The document discusses enhanced oil recovery (EOR) methods, focusing on steam injection. It defines EOR as techniques for extracting more crude oil from reservoirs beyond primary and secondary recovery methods. Steam injection is a thermal EOR method that involves injecting steam into reservoirs to lower oil viscosity and produce more oil. There are two main steam injection techniques - cyclic steam stimulation (also called huff-and-puff) which alternates between steam injection and production from single or multiple wells, and steam flooding which continuously injects steam into reservoirs to displace oil towards production wells. The document outlines some advantages and disadvantages of steam injection and economic considerations.
This document discusses primary recovery drive mechanisms for oil and gas fields. It describes the main types of primary drives including solution gas drive, gas cap drive, water drive, and gravity drainage. It provides details on how each drive works and its production trends. The document also discusses combination or mixed drive reservoirs that involve more than one drive mechanism. It emphasizes the importance of identifying the dominant drive when designing production wells in fields with mixed drives. Worked examples are provided at the end to illustrate calculations related to reservoir recovery factors and production timelines.

MPD familiarization Presentation april 2016.pptxcVNguyn5
Managed pressure drilling (MPD) is a drilling process that precisely controls the annular pressure profile to manage the downhole pressure environment and avoid continuous influx of formation fluids to the surface. MPD combines a rotating control device with surface control of annular pressure to control the wellbore pressure profile, rather than relying on mud weight alone. MPD can be applied reactively as a form of enhanced well control or proactively to mitigate drilling hazards and reduce non-productive time by enabling changes to drilling programs. Key MPD equipment includes the rotating control device, manifolds, chokes, and automated control systems.

The document provides equations and examples for analyzing fluid flow and pressure distribution during different flow regimes.
Difference between horizontal & directional drillingWe-Bore-It
Directional drilling and horizontal drilling are drilling processes that control the direction of drilling. Directional drilling allows drilling multiple wells from a single entry point and accessing locations not reachable by normal drilling. It can also avoid issues like fault drilling. Horizontal drilling extracts resources that are positioned horizontally and has benefits like reduced sand production, pressure, and increased oil recovery. Both techniques have applications in placing pipes under rivers or reservoirs.
This document discusses methods for calculating hydrocarbon volumes in reservoirs, including volumetric and material balance methods. It provides details on calculating oil, gas, and total hydrocarbon volumes based on parameters like porosity, net thickness, and saturation. It also covers reservoir drive mechanisms that can provide energy for hydrocarbon production, such as solution gas drive, gas cap drive, water drive, compaction drive, and combination drives. Reservoir performance data like pressure trends and gas-oil ratios can help identify the active drive mechanism.

The Proximity Log (PL) is a downhole tool designed to measure resistivity of the formation (RXO) without interference from thick mud cakes. It operates similarly to the Microlaterolog (MLL) but can penetrate deeper, up to 1.5 feet into the formation. The PL focuses current from a central electrode using guard electrodes to direct flow farther out than the MLL. Preliminary applications found the PL provides more accurate porosity measurements than the MLL when thick mud cakes are present.
We are all familiar with the production systems through which reservoir fluids flow to reach our processing facilities. This is a journey characterized by complex multiphase flow phenomena that govern pressure and temperature changes along the way. A monumental amount of research and development work has been invested towards better understanding multiphase flow behavior over the past fifty years. Yet, many challenges remain as we strive to optimize ever more complex production systems fraught with difficult flow assurance issues. Just how good is the science? And more importantly, how does this impact our bottom line? This lecture will discuss key concepts of multiphase flow leading to the current “state-of-the-art” models used today. Looking towards the future, the science must be advanced to address areas of greatest uncertainty and align with trends in field development strategies. Recommendations will be presented covering the top 5 areas of research necessary for these purposes. The economic impact of multiphase operations will be illustrated using two examples that provide insight towards maximizing asset value.

This document discusses various reservoir drive mechanisms used for oil recovery. It begins by defining reservoir drive mechanisms and categorizing recovery stages into primary, secondary, and tertiary. For primary recovery, the drive mechanisms described are solution gas drive, gas cap drive, water drive, and gravity drainage. Secondary recovery involves waterflooding and gasflooding to maintain pressure. Tertiary or EOR recovery discussed includes thermal methods using steam/hot fluids, chemical methods using polymers/surfactants, and miscible gas injection. Infill recovery occurs late in a reservoir's life through additional drilling.

This document discusses casing and cementing in oil and gas wells. It describes the five types of casing used: surface, conductor, intermediate, and production casing. It also discusses cement composition, slurry design, when cementing is required, and well cementing techniques.
